title: Preterm premature rupture of membranes in singleton vs twin pregnancies: The latency periods and the clinical outcomes revisited.
abstract: Our objective was to compare the latency periods after preterm premature rupture of membranes (PPROM) and determine its subsequent impact on maternal and fetal outcomes for singleton and twin gestations > 24 weeks' and ≤ 34 weeks' gestation. Delivery in the first 72 h after the rupture of membranes was observed to be more frequent in the twin group (RR 1.98, 95% CI 1.06-3.73, p = 0.03); whereas the overall median latency periods were comparable (p = 0.06). Singleton pregnancies had shorter latency periods after 28 gestational weeks by comparison to the latency periods before 28 weeks. Gestational age of rupture of membranes and delivery and latency periods were comparable between spontaneous twin pregnancies and twin pregnancies after assisted reproductive technologies (ART). As a conclusion, singleton and twin pregnancies had similar outcomes after PPROM. The first 72 h is especially important for the outcome of twin pregnancies at when the delivery risk is high.
