A 28-year-old primigravida at 34 weeks of gestation presents to the antenatal clinic with a blood pressure of 158/102 mmHg. She reports headache and right upper quadrant pain for the past 2 days. On examination, she has 3+ proteinuria on dipstick and brisk deep tendon reflexes. Platelet count is 95,000/μL, serum creatinine is 1.4 mg/dL, and AST is 120 IU/L. Fetal heart rate is 140 bpm with normal variability. What is the most appropriate immediate management?

Explanation

## Clinical Diagnosis: Severe Preeclampsia with HELLP Syndrome at 34 Weeks **Key Point:** This patient has severe preeclampsia with features of HELLP syndrome — thrombocytopenia (platelets 95,000/μL), elevated liver enzymes (AST 120 IU/L), elevated creatinine (1.4 mg/dL), RUQ pain, headache, and 3+ proteinuria. The combination of HELLP syndrome features with severe preeclampsia mandates **immediate delivery** regardless of gestational age, with magnesium sulfate for seizure prophylaxis. ### Rationale for Correct Answer (C) **High-Yield:** Per ACOG Practice Bulletin 202 and Williams Obstetrics (25th ed.), the presence of HELLP syndrome is an **absolute indication for delivery** regardless of gestational age. The 24–48 hour delay for corticosteroid administration is only permissible in cases of severe preeclampsia **without** HELLP syndrome, where maternal and fetal conditions remain stable. In this patient: - **Platelets < 100,000/μL** → HELLP criterion met - **AST > 70 IU/L (120 IU/L)** → HELLP criterion met - **Creatinine > 1.1 mg/dL** → End-organ dysfunction - **RUQ pain + headache** → Imminent eclampsia / hepatic capsule distension - **BP 158/102 with symptoms** → Functionally severe (ACOG: severe features include end-organ dysfunction even if BP < 160/110) Magnesium sulfate is administered concurrently for seizure prophylaxis. The route of delivery (cesarean vs. vaginal) depends on obstetric factors, but given the urgency and clinical picture, cesarean section under MgSO4 cover is appropriate. **Clinical Pearl:** The 24–48 hour corticosteroid window (Option B) is **NOT safe** when HELLP syndrome is present. Delaying delivery in HELLP risks maternal hepatic rupture, DIC, placental abruption, and maternal death. HELLP = deliver now. ### Why Other Options Are Wrong | Option | Reason Incorrect | |--------|-----------------| | A – Expectant management | Contraindicated; HELLP + severe features = deliver immediately | | B – Steroids + deliver in 24–48 hrs | Appropriate for severe preeclampsia WITHOUT HELLP; dangerous here | | D – Labetalol + defer to 37 weeks | Grossly inappropriate; HELLP mandates immediate delivery | ### HELLP Syndrome Criteria (Tennessee Classification) | Parameter | This Patient | Threshold | |-----------|-------------|-----------| | Platelets | 95,000/μL | < 100,000/μL ✓ | | AST | 120 IU/L | > 70 IU/L ✓ | | LDH (implied) | Elevated (creatinine 1.4) | > 600 IU/L | **Mnemonic: HELLP = Hurry, Expedite Labor/delivery with Labetalol + Prophylactic MgSO4** [cite: ACOG Practice Bulletin 202; Williams Obstetrics 25e Ch 40; Harrison's Principles of Internal Medicine 21e Ch 430]
