Wits Gynaecology Protocol and Management Guidelines
- Target Audience: These guidelines are intended as a practical guide for registrars, medical officers, interns, and medical students at University of the Witwatersrand Academic Hospitals.
- Contributors: W W Edridge, F Guidozzi, E J Buchmann, K Frank, A Wise, E Bera, H Rhemtula, and others.
- Spelling: Both American (e.g., gynecologist, hematologist) and English (e.g., gynaecologist, haematologist) spellings are accepted and included.
- Patient Communication: Explain everything (blood tests, surgery, prescriptions) without jargon or abbreviations. Use indigenous South African languages if English is not known.
- Medical Record Keeping: Findings and management must be recorded with date and time in the patient’s file. Note that smartphone entries are often too brief.
Blood Test Protocols for Specific Conditions
- Miscarriage: Hb, Compat (Typed and Held) if necessary, U&E, Rh.
- Septic Miscarriage: FBC, U&E, ABG, PI/PTT, HIV, Compat.
- Ectopic Pregnancy: Hb, U&E, hCG (in uncertain cases), Rh, Compat.
- Gestational Trophoblastic Disease (GTD): FBC, U&E, hCG, thyroid functions, Compat if necessary.
- First Trimester Termination: Rh, Ward Hb if slightly pale.
- Second Trimester Termination: FBC, U&E, Rh, Compat.
- PID Grade 1 (Out-patient): None required; HIV if unknown.

- Germ Cell Ovarian Tumor: Above plus AFP, hCG, LDH, LFT.
- Granulosa Cell Tumour: Inhibin (if available), LFT, E2 if post-menopausal.
Blood Transfusion and Surgical Guidelines
- X-Match (Cross-Match) Timing: Typed and held samples (Compat) can be cross-matched in 30−40 minutes, which is usually fast enough for theatre. Only request X-match if Hb is <10 for most operations.
- Necessary X-Match Indications: Ovarian malignancy, large fibroids, immobile masses, molar pregnancy evacuation, and abdominal pregnancies.
- Massive Transfusion/DIC: Request Fresh Frozen Plasma (FFP) and consider platelets. X-match early.
Clinical History and Physical Examination
- The "Big Five" Questions:
- Age
- Parity and gravidity
- Last menstrual period (LMP)
- Current contraception method
- Marital status and occupation (patient and partner)
- Pain Assessment: Duration, severity, localization, association with menstrual cycle, dyspareunia, urinary/bowel symptoms, and alleviating/aggravating factors.
- Bleeding Assessment: Amount, duration, clots, pain association, and discharge.
- Systematic Examination:
- General: Vitals (heart rate, temperature, BP, respiratory rate), mucous membrane color, and HIV stigmata (wasting, oral thrush, lymphadenopathy).
- Abdominal: Inspection for scars/hernias; palpation for organomegaly (liver, spleen, kidneys, uterus, ovaries) and tenderness (guarding/rebound); percussion for ascites.
- Pelvic Examination Rules:
- Empty bladder before the exam.
- Always perform a speculum exam before a bimanual exam.
- Use a small amount of lubricant on speculum blades (avoid tips when taking smears).
- Speculum Insertion: Part labia with the left hand, aim downwards with blades horizontal. If resistant, wait or turn vertically, then revert to horizontal.
- Bimanual Exam: Use one or two fingers in the vagina; press the abdominal hand downwards and towards the vagina.
- Rectal Examination: Mandatory for any pelvic/vaginal mass, gynae cancer, or suspected endometriosis to assess parametrium and recto-vaginal septum.
Lower Abdominal Pain (LAP) Differential Diagnosis
- Pelvic Inflammatory Disease (PID): Cervical motion tenderness is essential. Often overdiagnosed.
- Irritable Bowel Syndrome (IBS): Causes 50% of all LAP in women. Pain is chronic/intermittent; tenderness is in iliac fossae/suprapubically (higher than PID). Bimanual exam is normal.
- Dysmenorrhea:
- Primary: Begins with menarche, starts 24 hours before flow, lasts 24−48 hours.
- Secondary: Starts 24 hours before flow, lasts through the period; caused by fibroids, endometriosis, adenomyosis, or chronic PID.
- Endometriosis/Adenomyosis: Chronic pain worsening with menses; deep dyspareunia; potential infertility. Adenomyosis is felt as a tender, boggy uterus.
- Ovarian Cyst Accidents: Torsion (sudden severe pain), rupture, or bleeding. Ultrasound distinguishes between functional follicles (2.5cm) and pathological cysts.
- Wait and Prove: Ectopic pregnancy and miscarriage must always be considered in any patient of reproductive age with LAP.
- Lumbosacral Root Pain: Referred pain; worse on movement or rising; no abdominal signs.
- Acute Appendicitis: Abdominal signs typically exceed pelvic findings; positive Rovsing’s and Psoas signs.
Pelvic Inflammatory Disease (PID) Management
- Gainesville Grading:
- Grade I: Acute salpingitis without peritonitis.
- Grade II: Acute salpingitis with peritonitis.
- Grade III: Acute salpingitis with tubo-ovarian complex or tubal occlusion.
- Grade IV: Ruptured tubo-ovarian complex/generalized peritonitis.
- Outpatient Management (Grade I/II, Temp <38∘C, Pulse <100):
- Ceftriaxone 250mg IM stat (in 0.9ml lidocaine 1%).
- Doxycycline 100mg PO BD for 14 days.
- Metronidazole 400mg PO BD for 14 days.
- Alternative: Azithromycin 1g stat (repeated after 1 week).
- Inpatient Management (Grade II-IV):
- Penicillin G 6millionunits IV 6 hourly OR Ampicillin 500mg 6 hourly.
- Gentamicin 240mg IV daily OR Amikacin 1g IV daily.
- Metronidazole 1g rectally BD OR 500mg IV 12 hourly.
- Second-line: Tazocin 4.5g IV 12 hourly (may be used).
- Surgical Indications: Mass not responding to treatment, renal failure, dusky/necrotic cervix, or generalized peritonitis.
Early Pregnancy Problems: Ectopic Pregnancy
- Well Patients: Positive hCG, empty uterus on scan, and free fluid in Pouch of Douglas (POD).
- Observation/Conservative Criteria:
- hCG >5000U/L on transabdominal scan or >1000U/L on transvaginal scan with empty uterus suggests ectopic.
- Medical Management (Methotrexate):
- Requirements: Well patient, unruptured, no fetal heartbeat, diameter ≤3.5cm, hCG <10,000mIU/ml.
- Protocol: Methotrexate 50mg/m2 or 75mg IM/PO single dose. FBC, U&E, LFT must be checked first.
- Failure: 20% require surgery.
- Surgical Management:
- Standard: Total salpingectomy.
- Conservative: Salpingostomy/salpingotomy (preserving the tube).
- Shocked Patients: Resuscitate with two IV lines (14 or 16 gauge), X-match 4 units packed cells, urgent laparotomy.
Miscarriage Management
- Threatened: Bleeding, closed cervix, viable fetus. Reassure (at least 90% continue if fetal heart active).
- Inevitable: Open cervix, pain, bleeding, no products passed.
- Incomplete: Open cervix, products passed/visible.
- Management: MVA if <14−16 weeks and stable. If unstable: IV Ringer-Lactate + Oxytocin 20units in 1L.
- Complete: Positive test, empty uterus on scan, history of heavy bleeding with passed products.
- Septic Miscarriage: Hypotension, offensive products, tachycardia, pyrexia.
- Management: Triple IV antibiotics, emergency evacuation by senior staff. Hysterectomy required if cervix is gangrenous or generalized peritonitis exists.
- Hb Threshold: Hb 8g/dL is adequate for theatre evacuation if stable; others require transfusion to 10g/dL.
Gestational Trophoblastic Disease (GTD)
- Hydatidiform Mole:
- Diagnosis: "Grape-like" products or "snowstorm" ultrasound pattern.
- Prep: Hb <9g/dL requires 2 units transfusion. Avoid Misoprostol (causes excessive bleeding).
- Evacuation: Use suction curette + Oxytocin infusion 10−20units/1L.
- Follow-up:
- hCG every 2 weeks until <25Units/L, then monthly for 1 year.
- Avoid pregnancy during follow-up as hCG is the marker.
- Chemotherapy (WHO Scoring): Score 0−4 for low risk (single agent); ≥7 for high risk (combination).
Termination of Pregnancy (TOP)
- Legality (Choice on TOP Act, 1996):
- Up to 12 weeks: On request.
- 13−20 weeks: Risk to mother/fetus, rape/incest, or socio-economic grounds (requires 1 doctor).
- After 20 weeks: Endanger life, severe malformation, or injury to fetus (requires 2 doctors).
- Medical Protocols:
- <9 weeks: Mifepristone 200mg PO, then 24−48 hours later Misoprostol 800mcg PV.
- 9−13 weeks: Mifepristone 200mg PO, then 36−48 hours later Misoprostol 800mcg PV + 400mcg every 3 hours (max 4 doses).
- 13−20 weeks: Misoprostol 600mcg PV loading, then 400mcg every 3 hours (max 5 doses).

- Combined Oral Contraceptives (COC):
- Missed pill (>12 hours): Take missed pill, use precautions for next 7 days. If within 7 days of end of pack, skip pill-free interval.
- IUCD Insertion:
- LMP must be known. Uterine sound used to measure depth. Cut threads to 2−3cm.
- Antibiotic cover: Doxycycline and Metronidazole for 5 days.
- Sterilization: 18+ years only (unless life-threatening). Consent must emphasize permanence and small failure risk.
Abnormal Uterine Bleeding (AUB) and PALM COEIN
