title: Neonatal outcome in women with preterm premature rupture of membranes (PPROM) between 18 and 26 weeks.
abstract: OBJECTIVE
  The aim of this study was to identify adverse neonatal outcomes and identifies the predictors of adverse neonatal outcomes in premature rupture of membranes before 26 weeks.
  
  
  METHODS
  Data were collected between January 2005 and December 2011 from all pregnant women who presented preterm premature rupture of membranes (PPROM) between 18 and 26 complete weeks of gestation and were admitted to one of three Brazilian institutes. The adverse outcomes included mortality or the development of a severe morbidity during the length of stay in the neonatal intensive care unit (NICU). The descriptive statistics of the population were reported. A multiple logistic regression was performed for each predictor of neonatal adverse outcomes. The area under the receiver operating characteristics curves for the birth weight was calculated.
  
  
  RESULTS
  Composite adverse outcomes during the NICU stay occurred in 82.1% (n = 23) of the cases and included 33 (54%) neonatal deaths, 19 (67.8%) cases of retinopathy of prematurity (ROP), 13 (46.4%) cases of pulmonary hypoplasia (BPD), 8 (28.5%) cases of periventricular-intraventricular hemorrhage (PIH) and 3 (10.7%) cases of periventricular leukomalacia (PVL). Only 17.8% (n = 5) of the neonates survived without morbidity. The area under the curve for the birth weight was 0.90 (95% IC: 0.81-0.98) for the prediction of mortality.
  
  
  CONCLUSIONS
  PPROM before 26 weeks has a high morbidity and mortality, and the significant predictors of neonatal mortality and adverse outcomes were antibiotic prophylaxis, latency period, GA at birth and birth weight. Nevertheless, the only independent significant predictor of survival rate was birth weight.
