Given the polymicrobial nature of intra-amniotic infection, the recommended regimen includes a 7-day course of ampicillin and erythromycin, although many substitute of azithromycin. This regimen is used from viability to 34 weeks, independent of the number of fetuses present. Meta-analyses have shown that antibiotics for this indication are associated with lower rates of maternal and fetal infection, as well as longer pregnancy latency. Thus, latency antibiotics are recommended for all women with PPROM through 34 weeks of gestation.""Antenatal corticosteroids are important interventions to prevent neonatal morbidity and mortality associated with preterm birth. Administering intramuscular betamethasone or dexamethasone before preterm birth reduces risks of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and death. These same benefits are seen among women with preterm prelabor rupture of membranes (PPROM) without any proven increased risk of neonatal or maternal infection. Although future studies are needed to elucidate effects of antenatal corticosteroids at less than 23 weeks' gestation and a rescue course at later gestational ages after PPROM, a single course of antenatal corticosteroids is vital to optimizing neonatal outcomes after PPROM.""Trials evaluating tocolytic use in preterm premature rupture of membranes (PPROM) have been small and lacked adequate power to evaluate uncommon outcomes. There still is much controversy on the benefit, length of use, route, and drug of choice among clinicians treating patients with PPROM. Most professional medical societies would propose to consider the use of tocolytics for 48 hours to allow for corticosteroid administration or to allow for maternal transfer to a higher level of care.
