A 28-year-old primigravida delivers vaginally at term. Immediately after delivery of the placenta, she has a gush of vaginal bleeding estimated at 800 mL. Uterus is soft and boggy on palpation. Vitals: HR 102/min, BP 118/76 mmHg, RR 18/min. What is the most appropriate immediate next step in management?

Explanation

## Clinical Context This is a case of **primary postpartum hemorrhage (PPH)** — defined as blood loss >500 mL within 24 hours of vaginal delivery. The patient has: - Estimated blood loss of 800 mL (abnormal but not massive) - Soft, boggy uterus (classic sign of **uterine atony**, the most common cause of PPH) - Stable hemodynamics (HR 102 is mild tachycardia; BP normal) ## Management Algorithm for Atonic PPH ```mermaid flowchart TD A[PPH suspected: soft/boggy uterus]:::outcome --> B[Uterine atony?]:::decision B -->|Yes| C[Uterine massage]:::action C --> D[Administer oxytocin 10 U IM/IV]:::action D --> E{Bleeding controlled?}:::decision E -->|Yes| F[Continue IV fluids, monitor]:::action E -->|No| G[Consider ergot or misoprostol]:::action G --> H{Still bleeding?}:::decision H -->|Yes| I[Prepare for surgical intervention]:::urgent H -->|No| F ``` ## Why Uterine Massage + Oxytocin? **Key Point:** Uterine atony is the cause in ~80% of primary PPH cases. First-line management is **mechanical (massage) + pharmacological (oxytocin)** — not investigation or advanced intervention. **High-Yield:** The sequence for atonic PPH is: 1. **Uterine massage** — immediate mechanical stimulation 2. **Oxytocin 10 units IM** (or 5–10 units IV dilute in 500 mL saline over 5–10 min) — induces sustained uterine contraction 3. If unresponsive: ergot alkaloids (methylergonovine 0.2 mg IM) or misoprostol (800 μg PR) 4. If still uncontrolled: surgical (B-lynch suture, balloon tamponade, hysterectomy) **Clinical Pearl:** A soft, boggy uterus immediately after delivery is atony until proven otherwise. Do not delay uterine massage and oxytocin while waiting for investigations or blood products. ## Why Not the Other Options? | Option | Why Wrong | |--------|----------| | Tranexamic acid alone | Adjunctive agent (reduces transfusion need by ~30%), NOT first-line for atony. Used after oxytocin/ergot if bleeding persists. | | Foley + hysterectomy prep | Premature escalation. Patient is hemodynamically stable; atony usually responds to massage + oxytocin. Hysterectomy is last resort. | | Cross-match + ICU | Unnecessary at this stage. Patient is not in shock (BP normal, HR only mildly elevated). Blood products are reserved for ongoing/massive hemorrhage. | **Tip:** In NEET PG, always ask: *Is the patient in shock?* If NO and uterus is atonic, start with uterine massage + oxytocin. Save advanced measures for non-response.
