title: [Mode of delivery and perinatal outcomes in women with premature rupture of membranes at term].
abstract: OBJECTIVE
  Comparative study of delivery mode and perinatal outcomes in women with premature rupture of membranes at term compared to those with intact membranes.
  
  
  METHODS
  A cross sectional survey of all deliveries in 39 hospitals in 3 geographic regions of mainland China from January 1 to December 31, 2011 was carried out to investigate the demographic data and delivery outcomes.
  
  
  RESULTS
  In our analysis of 103 124 pregnancies, 14 073(13.6%) were complicated by premature rupture of membranes. Compared to those with intact membrane, the risks of postpartum hemorrhage, maternal complications and neonatal complications were increased significantly for women with premature rupture of membranes at term, especially the prevalence of neonatal respiratory distress syndrome(NRDS) and meconium aspiration syndrome. The risk of low Apgar (<7) at 1 minute was decreased for women with premature rupture of membranes at term.
  
  
  CONCLUSIONS
  The adverse perinatal outcomes are slightly higher in women with term premature rupture of membranes than those with intact membrane.
