The Pregnant Patient with Severe Preeclampsia and a Headache
A 32-year-old woman, gravida 2 para 1, at 34 weeks gestation presents with a severe frontal headache, visual scintillations, and right upper quadrant pain for 6 hours. BP 178/112 mmHg on two readings, HR 96, RR 20, SpO2 98%. Urine protein 3+ on dipstick. Platelets 88,000/µL, AST 142 U/L, creatinine 1.1 mg/dL. Fetal heart rate tracing shows a baseline of 150 with late decelerations. She is alone; her husband is 2 hours away. The obstetrician is in the operating room for an emergency cesarean and is unavailable for 30 minutes; the on-call anesthesiologist is available.
1. What is your immediate management, and how do you prioritize the competing maternal and fetal concerns?

Diagnosis: severe preeclampsia with severe features (BP ≥160/110, headache/visual symptoms, RUQ pain, thrombocytopenia <100,000, elevated AST). The late decelerations suggest placental insufficiency/fetal compromise, which is a delivery indication, but maternal stabilization comes first because maternal hypoxia, hypotension, or seizures will worsen fetal status.
Immediate priorities (in order):
- Magnesium sulfate loading dose (4–6 g IV over 15–20 min) for seizure prophylaxis - she has severe features and headache, which are the strongest predictors of eclampsia. Continue infusion.
- Blood pressure control: IV labetalol (or hydralazine/nifedipine per protocol) to bring BP to <160/110, avoiding precipitous drops that compromise uteroplacental perfusion. Target a controlled reduction, not normalization.
- Fetal monitoring continuously; position left lateral, oxygen if needed.
- Notify obstetrics and anesthesia immediately - the 30-minute OR delay is a communication problem, not a reason to wait. The anesthesiologist is available for airway/hemodynamic planning.
- Labs: repeat platelets, LFTs, creatinine, and check for HELLP; type and screen.
Maternal vs fetal: Stabilize the mother (Mg, BP) while arranging urgent delivery - the definitive treatment for severe preeclampsia is delivery. Do not delay delivery for a 'better' fetal tracing if maternal severe features persist.
2. The husband is 2 hours away and the patient is alone. She is alert and competent. What are the consent and communication considerations, and what if she develops eclampsia before the obstetrician arrives?
Read the worked answer
Consent: The patient is alert, oriented, and competent - she can consent for herself. Do not wait for the husband. Document her capacity and her consent. If she lacks capacity (e.g., eclampsia, altered mental status), proceed under emergency doctrine (implied consent for life-saving treatment) and document the emergency and the attempts to reach next of kin. The husband's absence does not block treatment.
Communication: Call the husband, explain the situation and plan, and document the call. Keep the patient informed at each step.
If she seizes (eclampsia) before the obstetrician arrives:
- Airway/breathing - left lateral position, oxygen, suction, protect from injury.
- Magnesium sulfate - if already loaded, give an additional bolus (e.g., 2 g IV over 5 min) per protocol; ensure the maintenance infusion is running.
- BP control with IV labetalol/hydralazine.
- Call obstetrics and anesthesia emergently - declare an emergency; do not wait 30 minutes.
- Prepare for emergent delivery - the definitive treatment. The anesthesiologist is available for airway and hemodynamic support.
- Monitor for magnesium toxicity (loss of reflexes, respiratory depression) and have calcium gluconate at the bedside.
Key judgment: Competent patient consents for herself; eclampsia is a life-threatening emergency that overrides the 30-minute delay.
