Severe hypertension in pregnancy is generally defined as a systolic pressure of 160 or higher, or a diastolic pressure of 110 or higher. When those numbers persist, urgent treatment isn't optional — it's the standard I hold every case to. So when I review these records, I want to know exactly when the first qualifying value appeared, when it was rechecked, the moment persistence was actually established, when the provider was notified, when medication was ordered and given, how the patient responded, and what monitoring followed after that.
The diagnosis depends on more than the blood pressure value alone. Symptoms, platelet count, liver enzymes, kidney function, pulmonary findings, fetal status, and how far along the pregnancy is — all of that shapes whether this is preeclampsia with severe features, and what the next steps should look like. It is also important to distinguish magnesium sulfate for seizure prophylaxis from antihypertensive therapy. Delivery timing is its own separate decision, one that has to weigh both the mother's condition and the baby's.
Postpartum cases deserve just as much attention — maybe more, because they're so easy to overlook. Preeclampsia can show up for the first time, or get worse, after delivery, sometimes after the patient has already gone home. So I look at the discharge blood pressures, what symptoms were present, what the patient was actually told to watch for, what follow-up was arranged, any phone calls that came in, how the ER triaged her if she came back, and whether obstetrics was ever consulted. A headache, visual changes, shortness of breath, chest pain, or pain under the ribs — any of these can change how urgently a patient needs to be seen.
What I'd caution both plaintiff and defense counsel against is measuring care with a stopwatch stripped of context. Timing absolutely matters, but a good expert has to pin down exactly when the emergency threshold was truly met, and then account for confirmation, access to medication, any contraindications, how the patient responded, and the realities of the clinical environment at that moment. The strongest opinion is built on a precise chronology — one that actually connects any alleged delay to the injury being claimed, rather than assuming a connection exists.
Questions for Counsel
- Were confirmed severe-range BP readings documented, and was antihypertensive treatment administered within 30-60 minutes as required — or is there a gap between the documented readings and the first medication administration?
- Were preeclampsia with severe features criteria evaluated — including laboratory assessment of platelet count, liver enzymes, and creatinine — and were abnormal values recognized and acted upon?
- Was magnesium sulfate initiated when clinically indicated, and was monitoring documentation (DTRs, respiratory rate, urine output) consistent with the standard of care?
- What was the gestational age at delivery, and was the decision to continue expectant management supported by the documented clinical picture and ACOG guidelines?
- Was the adverse outcome — whether eclampsia, stroke, HELLP, or fetal injury — foreseeable given the documented BP values and clinical deterioration, and could it have been prevented with earlier treatment?
