title: [Neonatal morbidity after conservative management followed by systematic delivery at thirty-four weeks of gestation in preterm rupture of membranes].
abstract: OBJECTIVE
  To evaluate the neonatal morbidity and its risks factors in case of uncomplicated preterm rupture of membranes managed conservatively with subsequent planned delivery at 34 weeks of gestation.
  
  
  METHODS
  We studied retrospectively 42 consecutive neonates systematically delivered at 34 weeks of gestation after more than 48 hours of conservative management for uncomplicated preterm rupture of membranes. Conservative management was conducted in a single tertiary care center and consisted in corticotherapy and in antibiotherapy (amoxycilline during 7 days). We evaluated the neonatal mortality rate, the incidence of infection, respiratory distress, neurological disorders, and we looked for their prenatal risks factors.
  
  
  RESULTS
  Forty-two neonates were included. The median gestational age at rupture was 31.1 weeks of gestation (from 25 to 33.9 weeks). The median duration of expectant management was 20 days (from 2.4 to 65 days). We observed 7 cases of neonatal infection but no septic failure, 18 cases of respiratory distresses among which 9 required a tracheal intubation for a mean duration of 3.7 days, no perinatal encephalopathy (5 cases of subependymal haemorrhage) and no neonatal death. We isolated one single risk factor that was the lowest gestational age at rupture in case of subsequent respiratory distress (29.6 vs 31.9 weeks; P=0.02).
  
  
  CONCLUSIONS
  Neonatal morbidity in this population consisted mainly in respiratory distresses with an increased incidence when gestational age at rupture decreased.
