Hypertensive Disorder at 34 Weeks with Fetal Compromise
A 31-year-old primigravida at 34+2 weeks presents with headache and epigastric pain. BP 168/112 mmHg on two readings, urine protein 3+ on dipstick, platelets 88,000/uL, AST 142 U/L, creatinine 1.1 mg/dL. Reflexes are brisk with 2 beats of clonus; she has visual scintillations. Fetal heart rate tracing shows baseline 165/min with recurrent late decelerations and reduced variability. Cervix is closed, long, and posterior; Bishop score 2. Ultrasound shows estimated fetal weight 1.9 kg, AFI 6.
1. Classify her condition and identify which findings drive the urgency of delivery.

This is preeclampsia with severe features, likely progressing toward HELLP syndrome.
Severe features present:
- BP ≥160/110 mmHg
- Symptoms: headache, visual scintillations, epigastric pain
- Platelets <100,000/uL (88,000)
- AST >2× upper limit (142)
- Neurological signs: brisk reflexes with clonus (impending eclampsia)
- Fetal compromise: late decelerations, reduced variability, oligohydramnios
HELLP criteria partially met: hemolysis (need LDH, schistocytes, indirect bilirubin), elevated liver enzymes (yes), low platelets (yes).
Urgency drivers:
- Maternal: imminent eclampsia (clonus + symptoms), severe hypertension, evolving HELLP.
- Fetal: recurrent late decelerations with reduced variability = category III / non-reassuring tracing, indicating placental insufficiency.
Both maternal and fetal indications converge on prompt delivery, not expectant management.
2. Outline your management from arrival to delivery, including mode of delivery and drug choices with doses.

1. Stabilize mother first (do not delay for steroids):
- Magnesium sulfate for seizure prophylaxis: 4 g IV loading over 15–20 min, then 1 g/h infusion. Monitor reflexes, respiratory rate, urine output; have calcium gluconate at bedside.
- Antihypertensive: IV labetalol 10–20 mg, or hydralazine 5–10 mg IV, or oral nifedipine 10 mg - target BP <160/110 (avoid over-lowering).
- Left lateral position, oxygen, continuous fetal and maternal monitoring.
2. Delivery decision:
- Category III tracing + severe features at 34 weeks = deliver now. Do not wait for a full steroid course; give dexamethasone 6 mg IM q12h for fetal lung maturity while preparing for delivery (benefit still accrues if delivered within 24–48 h; do not delay delivery for it).
- Mode: cervix is unfavorable (Bishop 2) and fetus is compromised - cesarean delivery is the safest route. Attempting induction risks further fetal hypoxia.
3. Anesthesia and intrapartum:
- Neuraxial anesthesia preferred if platelets permit (usually >70–80,000 and not falling rapidly) - discuss with anesthetist given 88,000 and possible HELLP.
- Anticipate neonatal resuscitation: 1.9 kg, 34 weeks - prepare warm environment, respiratory support.
4. Postpartum: continue MgSO4 for 24 h, monitor for eclampsia up to 6 weeks, watch for postpartum hemorrhage and pulmonary edema.
