Vilket medel aumlr baumlstbull Ropivacaine the S-isomer of the propyl homologue of
bupivacaine (Whiteside et al 2001) has approximately 50 of the potency of bupivacaine at equal doses when administered it (Gautier et al 1999 McDonald et al 1999)
bull Levobupivacaine is the S-enantiomer of bupivacaine with a lower degree of cardiotoxicity compared to racemic bupivacaine (Whiteside and Wildsmith 2001)
ndash Cardiotoxicity is not relevant with the bupivacaine doses (up to 20 mg) used in spinal anaesthesia
bull No difference was found between the spinal block after it bupivacaine or levobupivacaine (Alley et al 2002)
Dos och tid till utskrivning
ndash In a dose-response study of hyperbaric bupivacaine (375 ndash 1125 mg) in volunteers each additional mg of bupivacaine increased the time to home readiness by 21 min (Liu et al 1996)

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture
Svensk praxis ndash Knee arthroscopy routines and practice
bull Knee Surg Sports Traumatol Arthrosc 2010 Dec18(12)1656-60 Epub 2010 Sep 21bull Brattwall M Jacobson E Forssblad M Jakobsson Jbull Sourcebull Department of Anaesthesia Institute for Clinical Sciences at Sahlgrenska Academy Sahlgrenska University Hospital Moumllndal SE 431 80
Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Vilket medel aumlr baumlstbull Ropivacaine the S-isomer of the propyl homologue of
bupivacaine (Whiteside et al 2001) has approximately 50 of the potency of bupivacaine at equal doses when administered it (Gautier et al 1999 McDonald et al 1999)
bull Levobupivacaine is the S-enantiomer of bupivacaine with a lower degree of cardiotoxicity compared to racemic bupivacaine (Whiteside and Wildsmith 2001)
ndash Cardiotoxicity is not relevant with the bupivacaine doses (up to 20 mg) used in spinal anaesthesia
bull No difference was found between the spinal block after it bupivacaine or levobupivacaine (Alley et al 2002)

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Vilket medel aumlr baumlstbull Ropivacaine the S-isomer of the propyl homologue of
bupivacaine (Whiteside et al 2001) has approximately 50 of the potency of bupivacaine at equal doses when administered it (Gautier et al 1999 McDonald et al 1999)
bull Levobupivacaine is the S-enantiomer of bupivacaine with a lower degree of cardiotoxicity compared to racemic bupivacaine (Whiteside and Wildsmith 2001)

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

bull RESULTS All patients in Group HYP achieved T(10) dermatome analgesia but only 64 (1828) of Group PL T(10) analgesia was reached in 5 min (median range 5-20 min) in the HYP group vs 10 min (5-45 min) in the PL group (P=0022) and full motor block in 10 min (5-45 min) vs 20 min (5-60 min) (P=0003) respectively Group HYP had a longer duration of analgesia at T(10) 83 min (5-145 min) vs 33 min (0-140 min) (P=0004) Duration of sensory block from injection of the anesthetic to complete recovery was shorter in Group HYP than in Group PL 210 min (120-270 min) vs 270 min (210-360 min) (Plt0001) as was duration of motor block 120 min (5-150 min) vs 210 min (120-330 min) (Plt0001) Patients of Group HYP attained discharge criteria earlier than those of Group PL (P=0009)
bull CONCLUSION In comparison with the plain solution 15 mg of intrathecal hyperbaric ropivacaine produced a faster onset greater success rate of analgesia at the level of T(10) dermatome and faster recovery of the block
Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Vad paringverkar hur spinalen sprider sig
bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Vad paringverkar hur spinalen sprider sig
bull Greene reported 25 factors that could affect the distribution of the local anaesthetic in the cerebrospinal fluid (Greene 1985) but not all of them have clinical relevance
bull These factors can be classified into 4 subgroups characteristics of the patient and of the CSF characteristics of the local anaesthetic agent and the injection technique used (Table 2)
bull Besides the drug dosage the position of the patient at the time of injection and thereafter together with the baricity of the anaesthetic are the most important factors affecting the level of spinal anaesthesia (Stienstra and Greene 1991 Connolly and Wildsmith 1998 Enk 1998)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Selektiv unilateral spinalbull The advantages of unilateral or selective versus
conventional SA are ndash better haemodynamic stability (Tanasichuk et al 1961 Pittoni
et al 1995 Vaghadia et al 1997 Fanelli et al 2000) ndash faster motor and sensory recovery (Vaghadia et al 1997
Vaghadia 1998 Fanelli et al 2000) ndash decreased risk of urinary retention (Ben-David et al 1996 Ben-
David et al 1997 Ben-David et al 2000 Kuusniemi et al 2000a Mulroy et al 2002)
ndash The patientsrsquo satisfaction with the unilateral techniques has been high too (Pittoni et al 1995 Kuusniemi et al 1997 Kuusniemi et al 2000a)

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

bull Knee Surg Sports Traumatol Arthrosc 2010 Dec18(12)1656-60 Epub 2010 Sep 21bull Brattwall M Jacobson E Forssblad M Jakobsson Jbull Sourcebull Department of Anaesthesia Institute for Clinical Sciences at Sahlgrenska Academy Sahlgrenska University Hospital Moumllndal SE 431 80
Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture
Svensk praxis ndash Knee arthroscopy routines and practice

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

bull RESULTS All patients in Group HYP achieved T(10) dermatome analgesia but only 64 (1828) of Group PL T(10) analgesia was reached in 5 min (median range 5-20 min) in the HYP group vs 10 min (5-45 min) in the PL group (P=0022) and full motor block in 10 min (5-45 min) vs 20 min (5-60 min) (P=0003) respectively Group HYP had a longer duration of analgesia at T(10) 83 min (5-145 min) vs 33 min (0-140 min) (P=0004) Duration of sensory block from injection of the anesthetic to complete recovery was shorter in Group HYP than in Group PL 210 min (120-270 min) vs 270 min (210-360 min) (Plt0001) as was duration of motor block 120 min (5-150 min) vs 210 min (120-330 min) (Plt0001) Patients of Group HYP attained discharge criteria earlier than those of Group PL (P=0009)
bull CONCLUSION In comparison with the plain solution 15 mg of intrathecal hyperbaric ropivacaine produced a faster onset greater success rate of analgesia at the level of T(10) dermatome and faster recovery of the block
Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Unilateral spinal block for outpatient knee
arthroscopy a dose-finding study Borghi B et al A J Clin Anesth 2003 Aug15(5)351-6
CONCLUSIONS Hyperbaric bupivacaine 4 mg injected slowly through pencil-point directional needles in patients who are maintained in the lateral decubitus position for 15 minutes provided a surgical block that was mostly restricted to the operative side and adequate to perform knee arthroscopy with a faster recovery profile than when a 6 mg or 8 mg dose was used

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

ambulatory surgery of lower-extremities Hypothetically hyperbaric solution could improve and shorten the block
bull METHODS bull This prospective randomized double-blind study included 56 patients undergoing surgery
of lower extremities They received intrathecally either 15 ml of ropivacaine 10 mg ml(-1) and 05 ml of glucose 300 mg ml(-1) (HYP) or 2 ml of ropivacaine 75 mg ml(-1) (PL)
bull RESULTS bull All patients in Group HYP achieved T(10) dermatome analgesia but only 64 (1828) of Group PL T(10) analgesia was reached in 5
min (median range 5-20 min) in the HYP group vs 10 min (5-45 min) in the PL group (P=0022) and full motor block in 10 min (5-45 min) vs 20 min (5-60 min) (P=0003) respectively Group HYP had a longer duration of analgesia at T(10) 83 min (5-145 min) vs 33 min (0-140 min) (P=0004) Duration of sensory block from injection of the anesthetic to complete recovery was shorter in Group HYP than in Group PL 210 min (120-270 min) vs 270 min (210-360 min) (Plt0001) as was duration of motor block 120 min (5-150 min) vs 210 min (120-330 min) (Plt0001) Patients of Group HYP attained discharge criteria earlier than those of Group PL (P=0009)
bull CONCLUSION bull In comparison with the plain solution 15 mg of intrathecal hyperbaric ropivacaine produced a faster onset greater success rate of

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Comparison of hyperbaric and plain ropivacaine 15 mg in spinal anaesthesia for lower limb surgery
bull Br J Anaesth 2004 Nov93(5)664-9 Kallio H Snaumlll EV Tuomas CA Rosenberg PHbull BACKGROUND bull Previously plain ropivacaine 15 mg given intrathecally has been shown to be feasible for ambulatory surgery of lower-extremities
Hypothetically hyperbaric solution could improve and shorten the blockbull METHODS bull This prospective randomized double-blind study included 56 patients undergoing surgery of lower extremities They received intrathecally
either 15 ml of ropivacaine 10 mg ml(-1) and 05 ml of glucose 300 mg ml(-1) (HYP) or 2 ml of ropivacaine 75 mg ml(-1) (PL)
bull RESULTS All patients in Group HYP achieved T(10) dermatome analgesia but only 64 (1828) of Group PL T(10) analgesia was reached in 5 min (median range 5-20 min) in the HYP group vs 10 min (5-45 min) in the PL group (P=0022) and full motor block in 10 min (5-45 min) vs 20 min (5-60 min) (P=0003) respectively Group HYP had a longer duration of analgesia at T(10) 83 min (5-145 min) vs 33 min (0-140 min) (P=0004) Duration of sensory block from injection of the anesthetic to complete recovery was shorter in Group HYP than in Group PL 210 min (120-270 min) vs 270 min (210-360 min) (Plt0001) as was duration of motor block 120 min (5-150 min) vs 210 min (120-330 min) (Plt0001) Patients of Group HYP attained discharge criteria earlier than those of Group PL (P=0009)
bull CONCLUSION In comparison with the plain solution 15 mg of intrathecal hyperbaric ropivacaine produced a faster onset greater success rate of analgesia at the level of T(10) dermatome and faster recovery of the block
Comparison of plain and hyperbaric solutions of ropivacaine for spinal anaesthesia
bull Br J Anaesth 2005 Jan94(1)107-11 Epub 2004 Oct 29 Fettes PD Hocking G Peterson MK Luck JF Wildsmith JA
bull BACKGROUND Preliminary work has shown that ropivacaine provides spinal anaesthesia of shorter duration than bupivacaine and may be of particular use in the day-case setting However there are few data comparing the actions of plain and hyperbaric solutions of this drug
bull METHODS Forty ASA grade I-II patients undergoing elective perineal surgery under spinal anaesthesia were randomized to receive 3 ml ropivacaine 5 mg ml(-1) either in plain solution or with glucose 50 mg ml(-1) The extent and duration of sensory and motor block pulse rate blood pressure and time to mobilization were recorded
bull RESULTS Two patients (one per group) were withdrawn because of total block failure There were significant differences in median time to onset of sensory block at T10 (plain 10 min hyperbaric 5 min Plt001) median maximum extent (plain T8 hyperbaric T4 Plt005) and median duration of sensory block at T10 (plain 25 min hyperbaric 115 min Plt0001) However median times to complete regression of both sensory (270 vs 240 min Plt005) and motor (180 vs 120 min Plt0001) block were longer in the plain group Patients therefore mobilized sooner in the hyperbaric group (218 [n=16] vs 286 min [n=17] Plt001) All the hyperbaric blocks were adequate for surgery but three patients receiving plain ropivacaine required general anaesthesia
bull CONCLUSION Addition of glucose 50 mg ml(-1) to ropivacaine 5 mg ml(-1) increases the speed of onset block reliability duration of useful block for perineal surgery and speed of recovery Plain solutions are less reliable for surgery above a dermatomal level of L1

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Gothenburg Sweden methabrattwallvgregionsebull Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures thus consuming huge medical resources The aim of the
present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with

selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

A comparison of selective spinal anesthesia with hyperbaric bupivacaine and general anesthesia with
desflurane for outpatient knee arthroscopybull Anesth Analg 2004 Dec99(6)1668-73 Korhonen AM Valanne JV Jokela RM Ravaska P Korttila KTbull Abstractbull In this randomized and controlled trial 64 adult ambulatory knee arthroscopy patients received either
selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities a shorter stay in the postanesthesia care unit and earlier discharge home compared with GA with desflurane Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group ndash No difference was seen in the fast-tracking possibilities or time in the
postanesthesia care unit between the groups ndash Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS)
in the SSA and GA groups respectively ndash In the hospital the pain scores were significantly (P lt 0001) lower in the SSA
group compared with the GA group and the need for postoperative opioids was significantly (P = 0008) larger after GA
ndash The incidence of postoperative nausea and vomiting was 0 versus 19 in the SSA and GA groups (P = 0024) respectively
bull We conclude that for outpatients undergoing knee arthroscopy SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane

undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

Spinal anesthesia mediates improved early function and pain relief following surgical repair of ankle
fracturesbull J Bone Joint Surg Am 2010 Feb92(2)368-74 Jordan C Davidovitch RI Walsh M Tejwani N Rosenberg A Egol KAbull bull BACKGROUND To our knowledge no study to date has compared the use of spinal and general anesthesia in patients
undergoing operative fixation of an unstable ankle fracture The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients
bull METHODS Between October 2000 and November 2006 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia All patients were evaluated at three six and twelve months postoperatively with use of standardized validated general and limb-specific outcome instruments Standard and multivariable analyses comparing outcomes at these intervals were performed
bull RESULTS Four hundred and sixty-six patients (93) who had been followed for a minimum of one year met the inclusion criteria
bull Compared with the general anesthesia group the spinal anesthesia group had a greater mean age (p = 0005) higher classification on the American Society of Anesthesiologists system (p = 003) and a greater number of patients with diabetes (p = 002)
bull There was no difference in sex distribution between the groups bull At three months patients who received spinal anesthesia had significantly better pain scores (p = 003) and total
scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 002) At six months patients in the spinal anesthesia group continued to have better pain scores (p = 004) but there was no longer a difference in total scores (p = 006)
bull At twelve months no difference was detected between the groups in terms of functional or pain scores There was no difference in complication rates between the groups
bull CONCLUSIONS Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period We recommend that unless there is a specific contraindication patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture

present questionnaire survey was to study knee arthroscopy routines and practicebull METHODS bull An electronic web-based survey including questions around pre- per- and postoperative routines for elective knee arthroscopy was send to all
orthopaedic units associated to the Swedish Arthroscopic Society (n = 60)bull RESULTS bull Responses covering 37 centres out of 60 (response rate 62) were returned Preoperative radiograph routines varied considerable between
centres conventional radiograph varied between 5 and 100 and preoperative MRI between 5 and 80 of patients bull General anaesthesia was the preferred intra-operative technique used in all centres (median 79 of
patients) local anaesthesia with or without light sedation was used in all 28 out of the 37 centres responding (median 10 of cases) and spinal anaesthesia was used in 15 centres (median 5 of cases)
bull Intra-articular local anaesthesia was provided in all but one of centres Perioperative administration of oral NSAIDs was common (31 out 37) 6 centres (all teaching hospitals) did not routinely give pre- or postoperative NSAID
bull Analgesic prescription was provided on a regular base in 18 (49) of centres an NSAID being the most commonly prescribed All but one centre provided written information and instruction at discharge Referral to physiotherapy prescribed sick leave and scheduled follow-up in the outpatient clinic diverged considerably
bull CONCLUSION bull Routines and practice associated to elective knee arthroscopy differed however no clear differences in practice were seen between teaching
centres general or local hospitals apart from a lower usage of NSAID for perioperative analgesia There is an obvious room for further standardisation in the routine handling of patients undergoing elective arthroscopy of the knee
