RECOMMENDATIONS DEFINING THE FUNCTIONS, ROLE AND RESPONSIBILITIES OF THE CONSULTANT INTENSIVIST

Admissions to and discharges from the ICU 0 The consultant intensivist is ideally placed to triage patients, prioritise admissions and maintain a waiting list. 0 The presence of written protocols outlining how patient admissions will be prioritised is helpful. 0 When discharging a patient from the ICU, the consultant intensivist should be satisfied that the patient is suitable for transfer out of the ICU.

All patients admitted to the ICU must be seen by a consultant intensivist. 0 daily rounds on all ICU patients. 0 Make a clear plan for the next 12-24 hours. 0 Common ICU procedures should be performed by the consultant intensivist or by personnel designated by the consultant intensivist under his / her supervision.

0 Communication with patients and their families 0 End of life decisions 0 Time Commitment to the ICU 0 Privileges outside the ICU 0 Follow-up of patients outside the ICU 0 Maintaining standards of intensive care practice 0 Administration 0 Payments 0 Teaching 0 Research

Services outside the ICU 0 Management of patients in the high-dependency unit 0 Medical Emergency Team: 0 Emergency department, including the Trauma team 0 CPR team 0 Artificial airway management 0 Invasive procedures outside the ICU (e.g., Central Line, PICC lines, Lumbar puncture, Insertion of feeding tubes etc)

TRIAGE Due to the limited number of ICU beds, triaging may be necessary. The following factors will be taken into consideration in triaging: 0 Diagnosis 0 Severity of illness 0 Age and functional status 0 Co-morbid disease 0 Physiological reserve 0 Prognosis 0 Availability of suitable treatment 0 Response to treatment to date 0 Recent cardiopulmonary arrest 0 Anticipated quality of life

Discharge from the ICU 0 Conscious 0 Good airway, extubated and stable for several hours after extubation 0 Breathing comfortably 0 Stable blood pressure and urine output. 0 Haemoglobin >6 g/dl or blood transfusion in progress 0 Minimal nasogastric drainage and has bowel sounds, abdomen not distended 0 Afebrile 0 Looks better, sitting up, not confused.

Basic Bundle for all ICU patients A checklist: REMEMBER: FAST HUG 0 Feed 0 Analgesia 0 Sedation 0 Throboprophylaxis 0 Head of bed elevation 0 Ulcer prophylaxis 0 Glucose Control FAST HUG

CONTINUOUS INTRAVENOUS SEDATION 0 Patients are to be assessed for sedation and agitation based on the revised Riker Sedation and Agitation scale every 4 hours. The worst score within the last 4 hours is to be recorded. 0 Titrate the sedative infusion rate with the aim of keeping the sedation score between -1 to +1 0 Exceptions to keeping the sedation score between -1 and +1: a. head injured on cerebral protection: sedation score -3 b. severe sepsis on high inotropic support: sedation score of at least -1 c. RDS on high ventilatory support: sedation score of at least -2 d. tetanus: sedation score of at least -2

0 The standard sedative infusion to be used in patients admitted to ICU is midazolam and morphine. 30mg midazolam and 30mg morphine is diluted in up to 30mls normal saline. The infusion may be started between 2 3mls per hour 0 Fentanyl may be used instead of midazolam and morphine in the following conditions: a. renal failure b. hepatic failure 0 200mcg Fentanyl is diluted in up to 20mls normal saline. The infusion rate is between 2 - 5mls per hour (20 - 50mcg/hour) 0 Postoperative cases that are for overnight ventilation may be put on a. morphine + propofol b. dexmedetomidine (only for 24 hours) 0

0 Consider daily interruption of continuous sedative infusion at a fixed time every morning 0 If sedation score is +2, exclude other causes of agitation such as pain, hypoxia etc. Calm patient down by communicating with him. Increase the sedative infusion rate. 0 There may be a need to add further sedation For example: Tab. Lorazepam 1-2 mg ON / bd Tab. Alprazolam 0.5mg bd / tds 0 If sedation score +3, exclude other causes of agitation. Bolus midazolam/morphine and increase infusion rate except in non ventilated patients. IV haloperidol will probably be indicated: 1. Age < 60 years: 5 -10mg PRN / 4 -6hourly 2. Age > 60 years: 2.5 -5 mg PRN / 6 hourly

0 If sedation score: -2, half the intravenous sedative infusion. Decrease the sedative infusion every 4 hours until a score of -1 is achieved 0 If sedation score: -3, off sedative infusion. Assess 4 hours later. Restart at half the infusion rate once a score of -1 has been reached. 0 Patients that are paralysed need not be scored and should be denoted with a capital P

STRESS RELATED MUCOSAL DISEASE PROPHYLAXIS IN THE INTENSIVE CARE UNIT Specific risk factors include : 0 mechanical ventilation ( more than 48 hours) 0 coagulopathy 0 shock states ( septic, haemorrhagic, cardiogenic, anaphylactic) 0 severe head injury and neurosurgical patients 0 severe burns ( more than 30%) 0 multiple organ failure

Prophylactic therapy for SRMD Considering available evidence and cost-effectiveness of current pharmacological agents for prophylaxis, the following are recommended: 0 IV Ranitidine 50 mg 8 hourly. Reduce dose to 50 mg 12 hourly in patients with renal failure. 0 The superior efficacy of intravenous H2 antagonists compared with sucralfate in preventing SRMD has been demonstrated, and therefore, H2 antagonists are preferred. 0 The use of proton pump inhibitors (PPI) as prophylaxis has not been shown to be superior to H2 antagonists and should probably be limited to those with history of recent UGIB or recent endoscopically proven ulcer. 0 IV Omeprazole or IV Pantoprazole 40 mg daily

Discontinuing SRMD prophylaxis 0 Prophylactic therapy is discontinued once patient is on full feeds and none of the above risk factors are present. 0 Consider changing to oral therapy as soon as tolerating orally. 0 For those who develop clinically significant bleed in ICU, PPIs are continued for at least 2 weeks (IV / oral omeprazole or Pantoprazole 40 mg BD )

VENOUS THROMBOEMBOLISM PROPHYLAXIS RECOMMENDATIONS 0 On admission to the intensive care unit (ICU), all patients should be assessed for their risk of venous thromboembolism. 0 Consider withholding the heparin product when there is a significant decrease of platelet count (30 to 50% of initial count) or decrease to less than 100,000 per micro liter of blood or when INR > 1.5. 0 The prevention of VTE in neurosurgical has favoured mechanical prophylaxis methods. However the use of heparin products is considered to be safe after 48 to 72 hours.

0 The insertion and removal of epidural catheters should coincide with the nadir of the anticoagulant effect. The last dose of LMWH should be 12 hours prior to removal of catheter and can be restarted 2 hours later. 0 Routine screening of patients for asymptomatic deep vein thrombosis is not recommended since this strategy is neither effective nor cost-effective. 0 LMWH have a number of potential advantages over Low Dose unfractionated Heparin (LDUH) which include 1. once daily administration, greater bioavailability, lower incidence of heparin-induced thrombocytopenia and cost effective due to less laboratory monitoring 0 Early ambulation remains the most important non pharmacologic approach to prevention of VTE.

Pharmacological modalities 0 Low Dose unfractionated heparin (LDUH) eg. Subcutaneous (s/c) Heparin 5,000 units 8 hourly (high risk) or 12 hourly (moderate risk) 0 Low molecular weight Heparin (LMWH) eg. S/C Enoxaparin (Clexane) 40mg daily when creatinine clearance less than 30ml/min or 30mg daily when creatinine clearance greater than 30ml/min

ABSOLUTE RISK FOR VTE Patient categoryRecommendations Low risk eg. medical patients, immobilization, use of pharmacologic paralysis or sedation, heart failure Mechanical prophylaxis Moderate risk eg. general surgery, major gynecologic surgery, major urologic surgery, sepsis, vasopressor use, active medical condition LMWH or s/c Heparin 5000 units 12 hourly in combination with mechanical prophylaxis High risk eg. stroke, neurosurgery, previous VTE LMWH or s/c Heparin 5000 units 8 hourly in combination with mechanical prophylaxis Highest risk eg. spinal cord injury, major trauma hip/knee arthroplasty, hip fracture Surgery LMWH in combination with mechanical prophylaxis
