Women with mild gestational hypertension and preeclampsia without severe features can continue their pregnancies, if stable, until after 37 weeks and no longer need to have antihypertensive therapy, bed rest, or intrapartum magnesium sulfate. The task force still recommends magnesium sulfate therapy for pregnant women with severe preeclampsia, eclampsia, and HELLP syndrome at any gestational age. Delivery is recommended for women with severe preeclampsia including HELLP syndrome after 34 0/7 weeks or for those with unstable maternal and/or fetal conditions at any gestational age as soon as maternal stabilization is achieved. Immediate delivery is recommended for women who develop severe preeclampsia or HELLP syndrome prior to viability.
Recommendations for women between 24 and 34 weeks' gestation are more complex. Generally, recommendations include corticosteroids (ie, betamethasone), management of care at a tertiary care center, and antihypertensive therapy if blood pressure reading reaches the "severe" (160/110 mm Hg) range. For women who remain stable, daily fetal movement counting, twice weekly blood pressure checks, and weekly serum platelet counts and liver transaminases, biweekly antenatal testing, and serial growth scans are recommended.
Delivery is indicated for women in the 24- to 34-week range after completion of corticosteroids with preterm premature rupture of membranes, labor, persistent twofold increase in liver function tests, platelet count less than 100 000/microliter, fetal growth restriction less than 5 percentile, severe oligohydramnios, reversed end-diastolic flow on umbilical artery Doppler studies, and/or new-onset or worsening kidney dysfunction. Delivery may be expedited prior to completion of steroids if any of the following complications occur: uncontrollable, severe hypertension; eclampsia; pulmonary edema; abruption; disseminated intravascular coagulation; and nonreassuring fetal status or intrapartum fetal demise.
Postpartum recommendations for women with hypertensive disorders in pregnancy except chronic hypertension have changed as well. The task force now recommends 72 hours of observation during the immediate postpartum period.1 After the initial observation period, the blood pressure must be reassessed in 7 to 10 days; however, the development of any symptoms of preeclampsia is an indication for immediate reassessment. The task force does not recommend the use of antihypertensive medication until the blood pressure is 150 mm Hg systolic or 100 mm Hg diastolic or higher on at least 2 occasions 4 hours apart.
