To describe the perinatal outcomes after preterm premature rupture of membranes.
A retrospective cohort study was carried out at Instituto de Medicina Integral Prof. Fernando Figueira - IMIP from January 2008 to December 2012. A total of 124 preterm premature rupture of membranes singleton pregnancies, with gestational age <35, were included in the study. Pregnant women carrying fetuses with malformations, hypertensive syndromes, diabetes, or diagnosis of infections at admission were excluded. The pregnant women were hospitalized for conservative treatment with corticosteroids, antibiotics and tocolysis with nifedipine if necessary. The results are reported as frequency distributions and measures of central tendency and dispersion.
Seventeen patients (13.7%) had a gestational age of less than 24 weeks. Mean maternal age was 25.7 years, mean gestational age at the diagnosis of preterm premature rupture of membranes was 29 weeks, mean amniotic fluid index was 3.5 cm, and mean latency period was 10.5 days. Most patients went into spontaneous labor by the 30th week of pregnancy, and the rate of vaginal delivery was 88.2%. Chorioamnionitis was the most frequent maternal complication (34.7%). Neonatal sepsis was observed in 12% of patients, and the perinatal mortality rate was 21.5% for the group at or beyond the 24th week of gestation and 76.5% for the group with less than 24 weeks of gestational age.
A low maternal mortality rate was observed in preterm premature rupture of membranes; however, high rates of complications and perinatal death were observed, suggesting that other conduct protocols should be studied.

PURPOSE: to analyze obstetric and neonatal factors associated with bronchopulmonary dysplasia outcome in patients with preterm premature amniorrhexis. METHODS: we analyzed 213 medical records of patients of Fernandes Figueira Institute who suffered premature amniorrhexis (<34 weeks of gestation) in the period from 1998 to 2002. Multiple gestations were excluded. Clinical-obstetric and neonatal variables were considered in relation to the bronchopulmonary dysplasia outcome. Data were subjected to bivariate analysis, and the values showing statistical significance (p<0.05) were subjected to logistic regression analysis. RESULTS: the prevalence of bronchopulmonary dysplasia was 6.10%. Univariate analysis of the factors associated with the pulmonary dysplasia outcome were: neonatal mechanical ventilation for more than ten days(OR: 54.00 [11.55-278.25] p=0.000); birth gestational age of less than 30 weeks (OR: 6.33 [1.26- 43.06] p=0.017); birth weight <1,000 g (OR: 4.82 [1.34-17.53] p=0.010); birth weight <1.500 g (OR: 14.09 [1.82-300.50] p=0.003; patent ductus arteriosus (OR: 12.33 [3.07-50.10], p=0.000); hyaline membrane disease (OR: 8.46 [2.21-35.00] p=0.000); congenital pneumonia (OR: 7.48 [2.03-27.93] p=0.000); use of neonatal surfactant (OR: 19.66 [4.54-97.76] p=0.000), and neonatal infection (OR: 7.67 [0.99-163.79] p=0.049). In the final multivariate model, only the variables "neonatal mechanical ventilation">10 days (p=0.001) and "use of a surfactant" (p=0.040) remained independently associated with bronchopulmonary dysplasia. CONCLUSIONS: the factors associated with bronchopulmonary dysplasia are related to neonatal features, asprolonged mechanical ventilation and the use of a surfactant influencethe development of thedisease.
