Preeclampsia remains an important cause of maternal and neonatal mortality and morbidity. Delivery is always the appropriate therapy for the mother but may be responsible for neonatal adverse outcomes, particularly when it occurs at less than < 34 weeks' gestation. In women with severe preeclampsia at < 34 weeks expectant management to improve neonatal mortality and morbidity may be performed under close monitoring of both the mother and the fetus. Any severe condition of the mother (HELLP syndrome, abruptio placentae, eclampsia) or the fetus (abnormal fetal heart rate) should lead to prompt delivery. In women with mild preeclampsia, expectant management should be performed until 38 weeks gestation.
