Convulsions in hypertensive, proteinuric primiparas more than 24 hours after delivery. Eclampsia or some other cause?

A diagnosis of eclampsia has been considered inappropriate when the onset of a convulsion is greater than 24 hours after delivery. The observations presented here provide strong support for waiving the 24-hour rule, at least when convulsions from no other apparent cause and accompanied by hypertension and proteinuria occur in a primipara as late as 10 days postpartum. Late postpartum eclampsia seems an appropriate term for this very uncommon condition.
