Persistent Hypertension and Headache on Day 3 Postpartum
A 31-year-old woman, G1P1, delivered vaginally 3 days ago after an induced labour for pre-eclampsia. She was discharged on day 2 with a blood pressure of 138/88 mmHg and no antihypertensives. She returns to the health centre with a severe frontal headache that has worsened over 12 hours, visual blurring, and swelling of the face and hands. Blood pressure is 164/112 mmHg on two readings 15 minutes apart. Urine dipstick shows 3+ protein. Deep tendon reflexes are brisk with 2 beats of clonus. She is alert but says the light hurts her eyes. The health centre has magnesium sulfate, hydralazine, and a vehicle, but the referral hospital is 2 hours away on a rough road.
1. What is the diagnosis and severity, and which immediate treatments are indicated?
Read the worked answer
Diagnosis: severe postpartum pre-eclampsia with impending eclampsia. The combination of blood pressure at or above 160/110, neurological symptoms (headache, visual disturbance, photophobia), hyperreflexia with clonus, and heavy proteinuria defines severe disease. Onset after delivery is well recognised and can occur up to 6 weeks postpartum, so recent discharge is not reassuring.
Immediate treatment:
- Magnesium sulfate for seizure prophylaxis, using the standard regimen per local protocol (loading dose then maintenance). Monitor respiratory rate, urine output, and deep tendon reflexes; keep calcium gluconate at hand.
- Antihypertensive treatment for the severe range. Hydralazine is available and appropriate; give according to protocol and recheck blood pressure every 15-20 minutes. The aim is to bring blood pressure below the severe range, not to normalise it rapidly.
- Quiet, darkened room, minimal stimulation, and continuous observation by a midwife.
- Strict fluid balance with a urinary catheter if needed, because oliguria changes magnesium dosing.
Do not give diuretics or fluid boluses; both can worsen outcomes. Do not delay magnesium while arranging transfer.
2. The referral hospital is 2 hours away. How do you decide whether to treat and transfer or treat and keep her, and what is your monitoring plan?
Read the worked answer
Decision framework: the priority is to prevent a seizure and control blood pressure before moving. Transfer is appropriate once the woman is stable: blood pressure below the severe range, magnesium loading completed, no seizure, and an escort who can manage a seizure and airway. If a seizure occurs during transfer, the risk of aspiration and injury on a rough road is high, so the decision to move should be made by the most senior clinician available and documented.
Treat and transfer if: magnesium is running, blood pressure is responding, and an escort with magnesium and airway equipment is available.
Treat and keep (with emergency call for help) if: she seizes, develops pulmonary oedema, has a falling level of consciousness, or has oliguria with rising magnesium levels. In those cases stabilize first and arrange urgent retrieval.
Monitoring plan:
- Maternal pulse, blood pressure, respiratory rate, and oxygen saturation every 15 minutes initially.
- Deep tendon reflexes, clonus, and urine output hourly; record magnesium dose and time.
- Fetal assessment is not relevant here because she is postpartum, but newborn feeding and wellbeing should be checked.
- Watch for the signs of magnesium toxicity: loss of reflexes, respiratory depression, and reduced urine output. Stop the infusion and give calcium gluconate if these occur.
- Document headache and visual symptoms at each check; worsening neurology means escalate immediately.
After recovery, arrange postpartum follow-up for blood pressure and counselling about recurrence risk in future pregnancies.
