Postpartum eclampsia: a recurring perinatal dilemma.
Because identification of patients at risk and preventive therapies are imperfect, eclamptic seizures continue to occur occasionally during the puerperium. During an 18-year span in a single tertiary medical center, 36 of 254 patients with eclampsia (14.2%) experienced postpartum seizures at a mean gestational age of 35.6 weeks. Early (before 48 hours) postpartum eclampsia was experienced by 72% of patients, and 28% had late (after 48 hours) postpartum eclampsia. Prospectively only 67% of patients were correctly diagnosed, and retrospectively only 83% could be considered to have had preeclampsia before seizure. Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome was present in 30% of the affected patients. Seven patients were receiving magnesium sulfate by controlled infusion when an eclamptic seizure occurred. The presence or absence of diuresis was unrelated to seizure occurrence. Preeclampsia recurred in 38.5% of subsequent gestations. It appears that HELLP syndrome may be a predisposing factor for eclampsia.
