A 28-year-old multiparous woman at 28 weeks gestation presents with mild vaginal bleeding and mild abdominal discomfort for 6 hours. Vital signs are stable (BP 130/85, HR 88). Fetal heart rate is 145 bpm with reassuring variability. Ultrasound reveals a small retroplacental clot (2 cm) with 15% placental separation. Hemoglobin is 10.8 g/dL, and coagulation studies are normal. What is the most appropriate management?

Explanation

## Clinical Diagnosis: Grade 1 (Mild) Placental Abruption with Stable Maternal–Fetal Status **Key Point:** This patient has: - Small retroplacental clot (2 cm) with <25% placental separation (Grade 1) - Hemodynamically stable (normal BP, HR) - Reassuring fetal status (FHR 145, normal variability) - Normal coagulation profile (no DIC) - Mild bleeding that has stabilized **High-Yield:** **Expectant management** is the standard of care for uncomplicated, mild abruption with reassuring fetal status and maternal stability, even at preterm gestations. ## Abruption Severity Grading & Management | Grade | Separation | Bleeding | Fetal Status | Maternal Coagulopathy | Management | |-------|-----------|----------|--------------|----------------------|-------------| | **1 (Mild)** | <25% | Mild/none | Reassuring | None | Expectant | | **2 (Moderate)** | 25–50% | Moderate | Variable | Mild DIC | Individualize | | **3 (Severe)** | >50% | Severe | Distress | DIC | Emergency delivery | **Clinical Pearl:** In preterm abruption (28 weeks), the goal is to prolong gestation as long as maternal and fetal status remain stable. Each additional week improves neonatal outcomes. Corticosteroids (betamethasone 12 mg IM × 2 doses, 24 h apart) significantly reduce respiratory distress syndrome, intraventricular hemorrhage, and neonatal death. ## Management Pathway for Mild Abruption ```mermaid flowchart TD A[Mild Abruption<br/>Stable maternal/fetal]:::outcome --> B[Admit for monitoring]:::action B --> C[Corticosteroids<br/>for fetal lung maturity]:::action C --> D[Continuous CTG<br/>monitoring]:::action D --> E{Bleeding stops<br/>& FHR reassuring?}:::decision E -->|Yes| F[Expectant management<br/>until 34 weeks or labor]:::action E -->|No| G[Recurrent bleeding<br/>or fetal distress]:::urgent G --> H[Deliver immediately]:::urgent F --> I[Deliver at 34 weeks<br/>or spontaneous labor]:::outcome ``` **Mnemonic: STABLE** (criteria for expectant management in preterm abruption): - **S**mall clot (<25% separation) - **T**able: normal coagulation - **A**bdominal pain: mild or resolving - **B**leeding: minimal or stopped - **L**ive fetus: reassuring CTG - **E**xpectant: continue pregnancy if possible **Warning:** Do NOT discharge home at 28 weeks with abruption, even if mild. Risk of sudden massive hemorrhage, fetal demise, or labor onset requires inpatient monitoring. Amniocentesis is not indicated—fetal maturity assessment is secondary to maternal–fetal stability in abruption.
