Expectant management, with close monitoring of the mother and fetus, delays delivery when possible and reduces neonatal complications and length of stay in the newborn intensive care nursery.4749 Contraindications to expectant management include persistent severe symptoms, multiorgan dysfunction, severe IUGR (i.e., estimated fetal weight below the 5th percentile), suspected placental abruption, or nonreassuring fetal testing.49, In women with HELLP syndrome, the fetus is delivered at an earlier gestation; specifically, fetuses older than 28 weeks are routinely delivered 24 to 48 hours after the first maternal dose of corticosteroids is administered.34 Conservative management of HELLP syndrome remains experimental and, for most women, the clinical course is too rapid to complete the steroid regimen before initiating delivery.33, Vaginal delivery is recommended for women with severe preeclampsia if there is no evidence of maternal or fetal compromise or other obstetric contraindication.1 Some experts recommend cesarean delivery for fetuses younger than 30 weeks when the cervix is not ripe, but a trial of induction may be considered.1,7 In patients with HELLP syndrome, cesarean delivery carries special risks, such as bleeding from thrombocytopenia and difficulty controlling blood pressure because of depleted intravascular volume.33,34, Postpartum Management. HELLP Syndrome: hemolysis (rupture of RBCs), elevated liver enzymes, low platelets. A postictal phase may follow with confusion, agitation, and combativeness.
