Clinical Protocol Framework

Stepwise algorithms for common Obs-Gynae emergencies and clinical scenarios.

🌍

International Stepwise Protocol (WHO/ACOG/RCOG/NICE)

Universal algorithm for all Obs-Gynae presentations

1

History & Clinical Examination

Menstrual history, obstetric history (G/P/L/A), LMP, symptom duration and onset, associated features, systemic history, medications, allergies. Vitals: BP, HR, RR, SpO₂, temperature. Abdominal palpation, speculum, bimanual pelvic examination.

2

Identify & Stabilise Emergency Conditions

Immediate ABC assessment. Rule out: ectopic pregnancy, PPH, eclampsia, ovarian torsion, septic shock, cord prolapse. Activate emergency response if indicated. 2 large-bore IV cannulas + fluid resuscitation + oxygen if haemodynamically unstable.

3

Formulate Differential Diagnosis

Systematic listing ranked by clinical probability and urgency. Pregnancy-related causes first in reproductive-age women. Use PALM-COEIN for AUB, 4 T's for PPH, Rotterdam for PCOS.

4

Targeted Investigations

βhCG, FBC, coagulation, USS, hormonal assays as clinically indicated. Interpret results in clinical context. Escalate to MRI/CT/laparoscopy when USS insufficient.

5

Evidence-Based Medical Therapy

Prescribe per WHO/ACOG/RCOG guidelines. Consider drug safety in pregnancy (FDA pregnancy categories). Dose adjust for renal/hepatic function. Counsel on side effects and compliance.

6

Surgical / Procedural Intervention

When medical management fails or primary surgical indication exists. Options: laparoscopy, hysteroscopy, caesarean section, uterine balloon tamponade, UAE, hysterectomy as per escalation protocol.

7

Follow-up, Monitoring & Documentation

Serial assessments, medication monitoring, patient education, informed consent documentation. Multidisciplinary team involvement for complex cases. Postnatal review, contraception counselling.
