INTRODUCTION
• Preoperative care is the preparation and management of a patient prior to surgery.
• It includes both physical and psychological preparation.
• Surgical treatment of the patients with gynecologic diseases is warranted only when all the conservative treatment approaches have been exhausted.
![Page 4: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/4.jpg)
• Many postoperative problems can be anticipated preoperatively, and eliminated or minimized.
• There are two groups of indications for gynecological surgery: Absolute - when surgery must be undertaken,
when its cancellation is life threatening.Relative - when surgery can be postponed till the
most appropriate occasion for its performing.
![Page 5: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/5.jpg)
• The surgeon is obliged to introduce to the patient all the reasons of the surgical treatment.
INFORMED CONCENT:• The patient must submit an informed written
consent to confirm that she takes the risk of the planned surgical treatment.
• discussion regarding consent should be held with a qualified interpreter present.
![Page 6: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/6.jpg)
• The presence of an interpreter should be included in the documentation.
• The informed consent discussion should include the following:– Rationale– Complications– Unexpected findings at surgery– Personnel who will be involved in the surgery.– Documentation
![Page 7: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/7.jpg)
PREOPERATIVE EVALUATION
• Used to addresses issues that will potentially affect the woman during her surgical procedure and recovery.
• The surgeon should use this time to review:– the patient's history – physical examination– identify physical limitations
![Page 8: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/8.jpg)
– gather information required to plan surgery– optimize medical status, and – educate about what to expect from the
procedure and during the recovery period.Patient history• A comprehensive history is the first step
helping surgeons to determine the scope of general physical examination, laboratory, and radiologic tests.
![Page 9: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/9.jpg)
• The patients undergoing minor surgery can be examined by their surgeon and anesthesiologist on the operation day during preoperative preparation but
• those with more serious conditions should be examined at least a week before surgery, allowing the time for risk assessment, specialist consultations, and preparation.
![Page 10: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/10.jpg)
General medical history: includes • Personal and family diseases• History of drug use• Allergies to drugs, foods, and other environmental allergens• Hospitalizations• Earlier diseases (including previous operations and
tolerance of anesthetics).• Important family data refer to malignancies, cardiovascular
diseases, diabetes mellitus, cerebrovascular diseases, and osteoporosis.
![Page 11: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/11.jpg)
Gynecologic and obstetric history • should contain the data about major
complaints of the current disease (beginning, duration, symptoms).
• past pregnancies (description of each, duration, complications, type of delivery)
![Page 12: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/12.jpg)
• menstrual cycle data (intervals, duration, copiousness, dysmenorrhea, premenstrual syndrome, intermenstrual bleeding)
• menarche; data on the last menstruation• if the patient is age at menopause, recent
vaginal bleeding, vasomotor symptoms, hormone replacement therapy.
![Page 13: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/13.jpg)
• birth control (if sexually active - active contraception, methods in the past; if sterilized - time and mode of sterilization).
• sexual history• birth control (conception difficulties, infertility
treatment)• infections (vaginal discharge, previous vaginal
infections, sexually transmitted diseases).
![Page 14: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/14.jpg)
Clinical (physical) examination• The aim of the physical examination is to
establish the physical, health status, in view of history and medical condition.
• Full physical examination is needed.• detailed exam of the abdomen and pelvis, as
the main component of the procedure.
![Page 15: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/15.jpg)
Anesthesiologic preoperative examination • An anesthesiologist has to examine the patient before
her operation.why?– b/c it helps him to get an insight into the
general health condition, and– to assess whether the patient is able to tolerate
the risks and duration of anesthesia for the planned surgery.
• A special stress is put on the state of consciousness and vital functions of the heart, blood vessels, liver, and kidneys.
![Page 16: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/16.jpg)
Anesthesiologic surgical risk is assessed based on the assessment of physical status created by the American Society of Anesthesiology – ASA:
• Group I- original disease, if it is without a systemic im-pact
• Group II - moderate systemic disease without functional impediments
• Group III - severe systemic disease with serious functional impediments
• Group IV- severe systemic life-threatening disease
![Page 17: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/17.jpg)
• Group V- moribund patient, with 24 hours; and
• Group VI- confirmed brain death INVESTIGATION• Preoperative indications for laboratory tests
– Patient age– diagnosis of the disease and – risk of the procedure with careful and detailed
history and physical examination.
![Page 18: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/18.jpg)
• blood group determination• complete blood count with the leukocyte
formula, sedimentation, bleeding and coagulation time, thrombocytes, fibrinogen.
• Renal function test• liver function test• Blood glucose level• General analysis of the urine and urine culture
![Page 19: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/19.jpg)
• Pregnancy test Pregnancy testing should be performed shortly
before surgery on all fertile women who could be pregnant.
• Imaging studies are often performed to select patients who will not
benefit from surgery (eg, metastatic disease) or to help biopsy tissue for diagnosis of suspicious
masses
![Page 20: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/20.jpg)
• Imaging study includes An intravenous pyelogram (IVP) Computed tomography (CT) magnetic resonance imaging (MRI), and Ultrasound
NB:Preoperative chest x-rays should not be routinely performed.
• Investigation specific to patients problem.
![Page 21: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/21.jpg)
PREOPERATIVE PREPARATION
• It is important to allow adequate time for preparation prior to surgery. This includes:
1-Correction of anemia: Strategies to correct anemia preoperatively are:-
Iron supplementation Medical treatment of abnormal uterine
bleeding Erythropoiesis-stimulating agents Blood transfusion
![Page 22: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/22.jpg)
2-Smoking cessation: Patients undergoing elective surgery should be
advised to stop smoking at least eight weeks before surgery.
Preoperative smoking cessation may decrease wound complications, particularly wound infection.
![Page 23: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/23.jpg)
3-Medical consultation and stabilization The consultant should be asked specific
questions, such as is thyroid replacement adequate hypertension well controlledCHD optimally managed, and diabetes under control
![Page 24: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/24.jpg)
4-Bowel preparation: The gynecologic surgery literature does not
address the safety and efficacy of mechanical bowel preparation.
In general, you can expect to: Modify the dietTake a laxative or bowel preparation medication Increase fluid intake
![Page 25: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/25.jpg)
5-preoperative antibiotics: Provision of optimal local immunity to infection
is primarily a surgical task. A single dose of antibiotic immediately before
the operation is sufficient for most surgical procedures.
If the operation is going to take more than 3 hours, administration of antibiotics should be repeated.
![Page 26: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/26.jpg)
• In time consuming interventions intramuscular administration of antibiotics is preferred.
• Prophylactic use of antibiotics have been demonstrated to be more successful for vaginal compared to abdominal operations.
• Adequate use of antibiotics is able to reduce the rate of infections, as well as morbidity and associated costs .
![Page 27: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/27.jpg)
Recommendation for choosing antibiotcs in postoperative infection prophylaxis:
• Cephalosporins first generation: up to 2,0 grammes
• Metronidazole 0,5 - 1,0 grammes + gentamicin 1,5 mg/kg iv.
• Clindamycin 600 - 900 mg iv + Gentamicin 1,5 mg/kg
• Ciprofloxacin 400 mg iv
![Page 28: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/28.jpg)
Thromboprophylaxis: reduces the incidence of symptomatic DVT or
pulmonary embolism. Types of thromboprophylaxis —
pharmacologic or mechanical
![Page 29: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/29.jpg)
Pharmacologic prophylaxis includes Low-dose unfractionated heparin (LDUH) —
5000 units subcutaneously (SC) every 8 to 12 hours.
Low molecular weight heparin (LMWH) — Dalteparin 2500 units or enoxaparin 40 mg SC daily.
NB: The use of aspirin for prophylaxis is NOT recommended, as other measures are more efficacious.
![Page 30: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/30.jpg)
• Mechanical methods of thromboprophylaxis are placed on the patient just prior to the start of surgery and used continuously until hospital discharge.
• Most commonly used methods in gynecologic surgery are:Intermittent pneumatic compression boots (IPC)Graduated compression stockings (GCS)
![Page 31: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/31.jpg)
Which patients need thromboprophylaxis? The ACCP recommendations for women undergoing
gynecologic surgery are:Low risk (ie, minor surgery in mobile patients) AND/OR
entirely laparoscopic procedures with NO additional VTE risk factors — Do not require specific prophylaxis, but early and frequent ambulation is advised.
Entirely laparoscopic procedures WITH additional VTE risk factors — Mechanical, pharmacologic thromboprophylaxis, or both.
![Page 32: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/32.jpg)
Major gynecologic surgery for benign disease with NO additional risk factors — IPC or pharmacologic thromboprophylaxis.
Major gynecologic surgery for malignancy AND/OR in patients WITH additional risk factors — Pharmacologic therapy (LDUH should be given every eight hours).
Patients who have undergone major surgery for malignancy AND/OR have a previous history of VTE should continue LMWH for up to 28 days.
![Page 33: preoperative care for gyecologic patient](https://reader038.vdocuments.us/reader038/viewer/2022110307/5560fbe8d8b42a91388b4f6c/html5/thumbnails/33.jpg)
CONCLUSION
• Preoperative patient preparation for gynecologic surgery is
to avoid or minimize both intra and postoperative complications, and
enabling a successful outcome of surgery.
