Furosemide for Prevention of Severe Postpartum Hypertension: a Randomized Controlled Trial

The purpose of this study is to determine whether postpartum administration of furosemide to women with antepartum hypertensive disorders (gestational hypertension, preeclampsia) or elevated blood pressure in the first 24 hours following delivery reduces severe postpartum hypertension.
