Hypertensive syndrome that occurs in pregnant women after 20 weeks' gestation, consisting of new-onset, persistent hypertension with either proteinuria or evidence of systemic involvement.
All pregnant women presenting with hypertension and either proteinuria or evidence of systemic involvement require close assessment and monitoring for preeclampsia and its complications.
Delivery is the definitive treatment; the decision about when and how to deliver should only be made after a thorough assessment of the risk and benefits to the mother and baby.
Other mainstays of management include antihypertensive therapy, seizure control, and fluid restriction.
Maternal mortality is highest after delivery, so vigilance should be maintained in the postpartum period.
Can occur in subsequent pregnancies; therefore, women should be counseled about the risk.
A disorder of pregnancy associated with new-onset hypertension (defined as a blood pressure ≥140 mmHg systolic and/or ≥90 mmHg diastolic), which occurs most often after 20 weeks of gestation and frequently near term. Although often accompanied by new-onset proteinuria, hypertension and other signs or symptoms of preeclampsia may present in some women in the absence of proteinuria.
