A 32-year-old primigravida at 34 weeks gestation presents to the emergency department with sudden onset of severe abdominal pain and vaginal bleeding. She reports a history of hypertension (BP 160/100 mmHg currently) and denies any recent trauma. On examination, the uterus is tender and rigid with board-like consistency. Fetal heart rate is 80 bpm. Ultrasound shows a retroplacental collection. Her hemoglobin is 8.2 g/dL (baseline 11.5 g/dL), and coagulation profile shows PT 16 sec, aPTT 42 sec, fibrinogen 120 mg/dL. What is the most appropriate immediate management?

Explanation

## Clinical Diagnosis: Placental Abruption with Maternal and Fetal Compromise ### Key Clinical Features **Key Point:** This patient has severe abruption (Grade 3) with: - Maternal hypertension (risk factor) - Severe vaginal bleeding + abdominal pain - Board-like rigid uterus (concealed hemorrhage) - Fetal bradycardia (80 bpm; normal >110 bpm) - Retroplacental clot on ultrasound - Consumptive coagulopathy (low fibrinogen 120 mg/dL, prolonged PT/aPTT) ### Why Immediate Cesarean Delivery? **High-Yield:** Severe abruption with fetal distress (bradycardia) and maternal coagulopathy requires urgent delivery to: 1. Stop ongoing placental separation and hemorrhage 2. Prevent maternal DIC progression 3. Resuscitate the compromised fetus **Clinical Pearl:** Fibrinogen <100 mg/dL indicates severe consumptive coagulopathy; transfusion of FFP (10–15 mL/kg) is essential before and during surgery to restore hemostasis. ### Management Algorithm ```mermaid flowchart TD A[Suspected Abruption]:::outcome --> B{Maternal/Fetal Stability?}:::decision B -->|Stable, <34 wks, no bleeding| C[Expectant: corticosteroids, monitoring]:::action B -->|Fetal distress OR maternal instability| D[Grade 2–3 Abruption]:::urgent D --> E[Activate massive transfusion protocol]:::action E --> F[Type & cross, FFP, PRBCs ready]:::action F --> G[Immediate cesarean delivery]:::action G --> H[Maternal resuscitation + coagulopathy correction]:::action H --> I[Neonatal resuscitation]:::action ``` **Mnemonic:** **CRASH** for severe abruption management: - **C**oagulopathy assessment (fibrinogen, PT/aPTT) - **R**esuscitation (IV access, fluids, blood products) - **A**ctivate massive transfusion protocol - **S**urgical delivery (cesarean) - **H**emostasis (FFP, cryoprecipitate, platelets as needed) ### Why NOT Other Options? | Option | Why Incorrect | |--------|---------------| | Expectant management | Fetal bradycardia is a sign of acute fetal compromise; waiting for corticosteroids will worsen fetal outcome and maternal bleeding. | | Vaginal delivery with oxytocin | Severe abruption with fetal distress requires immediate delivery; vaginal delivery delays definitive hemostasis and risks maternal exsanguination. | | Tocolysis with nifedipine | Contraindicated in abruption; tocolytics delay delivery and allow continued placental separation and hemorrhage. | [cite:Williams Obstetrics 25e Ch 34]
