Prelabor Rupture of Membranes at Term

Obstet Gynecol; ePub 2018 Jan; ACOG, Ehsanipoor

The American College of Obstetricians and Gynecologists (ACOG) has issued an interim update on the optimal method of initial management for a patient with prelabor rupture of membranes (PROM) at term. The document provides management guidelines that have been validated by appropriately conducted outcome-based research. Additional guidelines on the basis of consensus and expert opinion are also presented. Among the (Level A) recommendations:

  • Patients with PROM before 34 0/7 weeks of gestation should be managed expectantly if no maternal or fetal contraindications exist.
  • To reduce maternal and neonatal infections and gestational-age dependent morbidity, a 7-day course of therapy with a combination of intravenous ampicillin and erythromycin followed by oral amoxicillin and erythromycin is recommended during expectant management of women with preterm PROM who are less than 34 0/7 weeks of gestation.
  • Women with preterm PROM and a viable fetus who are candidates for intrapartum GBS prophylaxis should receive intrapartum GBS prophylaxis to prevent vertical transmission regardless of earlier treatments.
  • A single course of corticosteroids is recommended for pregnant women between 24 0/7 weeks and 34 0/7 weeks of gestation, and may be considered for pregnant women as early as 23 0/7 weeks of gestation who are at risk of preterm delivery within 7 days.
  • Women with preterm PROM before 32 0/7 weeks of gestation who are thought to be at risk of imminent delivery should be considered candidates for fetal neuroprotective treatment with magnesium sulfate.
