A 32-year-old woman, 6 hours postpartum after vaginal delivery, develops sudden heavy vaginal bleeding (estimated 1200 mL in 30 minutes). She is pale, anxious, with HR 118/min, BP 92/58 mmHg, RR 22/min. Uterus is firm and well-contracted. Lochia is dark and clotty. What is the most appropriate immediate next step?

Explanation

## Clinical Context This is a case of **secondary postpartum hemorrhage with hemodynamic instability**: - Massive blood loss (1200 mL in 30 min) occurring 6 hours postpartum - Signs of hypovolemic shock: HR 118, BP 92/58, RR 22, pallor, anxiety - **Firm, well-contracted uterus** — rules out uterine atony - Dark, clotty lochia — suggests coagulopathy or retained clots ## Differential Diagnosis of PPH with Firm Uterus | Cause | Key Feature | Next Step | |-------|-------------|----------| | **Genital tract trauma** (cervical, vaginal, perineal lacerations) | Firm uterus, visible bleeding from lower tract | Examine under good light; repair lacerations | | **Retained products of conception** | Firm uterus, clotty lochia, uterine tenderness | Manual exploration ± curettage | | **Coagulopathy** (DIC, amniotic fluid embolism) | Firm uterus, oozing from multiple sites, prolonged PT/PTT | FFP, platelets, cryoprecipitate | | **Uterine rupture** (rare) | Firm uterus initially, then shock + abdominal pain | Emergency laparotomy | ## Why Immediate Resuscitation + Examination? **Key Point:** The patient is in **hemorrhagic shock** (BP <100 mmHg, HR >110, altered perfusion). The immediate priority is: 1. **Stabilize** — large-bore IV access, rapid fluid resuscitation (crystalloid, then blood products) 2. **Identify source** — examine genital tract under good light (most common cause of PPH with firm uterus is **trauma**) **High-Yield:** The "4 T's" of PPH: - **Tone** (atony) — soft uterus → uterine massage + oxytocin - **Tissue** (retained products) — firm uterus, clotty lochia → manual exploration - **Trauma** (lacerations) — firm uterus, visible bleeding → examine and repair - **Thrombin** (coagulopathy) — firm uterus, oozing → FFP, platelets, cryoprecipitate **Clinical Pearl:** In shock, the sequence is **ABCs first**: airway, breathing, circulation (fluids, blood). Do not delay resuscitation to perform investigations or advanced procedures. ## Why Not the Other Options? ```mermaid flowchart TD A[PPH + Shock: BP 92/58, HR 118]:::urgent --> B[Establish IV access + fluid resuscitation]:::action B --> C{Uterus firm?}:::decision C -->|Yes| D[Examine genital tract for trauma]:::action D --> E{Laceration found?}:::decision E -->|Yes| F[Repair under anesthesia]:::action E -->|No| G[Consider manual exploration or imaging]:::action C -->|No| H[Uterine massage + oxytocin]:::action ``` | Option | Why Wrong | |--------|----------| | Ergot alkaloids alone | Uterus is already firm — ergot will not help. Delaying resuscitation and examination is dangerous in shock. | | Manual exploration first | Correct procedure, but NOT before resuscitation. Shock takes priority. Also, trauma must be ruled out first (easier to visualize than explore). | | FFP + laparotomy | Premature. No evidence of uterine rupture (no abdominal pain, no peritoneal signs). Coagulopathy is secondary to massive transfusion, not primary. | **Tip:** In NEET PG, when you see **shock + PPH**, think **ABCDE** (Resuscitation first). Diagnosis and specific treatment come after stabilization.
