title: [Elective cesarean section is preferred after the completion of a minimum of 38 weeks of pregnancy].
abstract: OBJECTIVE
  To determine the frequency of neonatal respiratory morbidity following elective caesarean delivery at term and to identify prognostic factors for this morbidity.
  
  
  METHODS
  Retrospective.
  
  
  METHODS
  Academic Hospital Utrecht/Wilhelmina Children's Hospital Neonatal Intensive Care Unit, Utrecht, the Netherlands.
  
  
  METHODS
  All elective caesarean deliveries in the Academic Hospital Utrecht from the period 1990-1995 were studied. Also, neonates were included who were admitted for intensive neonatal care because of respiratory insufficiency following elective caesarean delivery in the region surrounding Utrecht. An elective caesarean delivery was defined as a delivery performed after 37 weeks of gestation without any complicating factor that might influence the timing of delivery. Prognostic factors for neonatal morbidity after caesarean delivery were identified by multivariate logistic regression analysis.
  
  
  RESULTS
  During 1990-1995, 272 elective caesarean deliveries after 37 weeks of gestation were performed that fulfilled the inclusion criteria; 5.1% of the neonates were admitted to the medium care unit because of respiratory problems. The relative risk of respiratory morbidity after delivery by caesarean section with a gestational age of 39-42 weeks compared with a gestational age of 37-38 weeks, was 0.14 (95% confidence interval: 0.03-0.64; p < 0.001). Male sex was a cofactor. Nine neonates of whom 8 (90%) had a gestational age of less than 39 weeks were admitted to the intensive care unit.
  
  
  CONCLUSIONS
  Most of neonatal respiratory morbidity could have been avoided by postponement of the at-term elective caesarean section until a certain gestational age of at least 38 complete weeks. An elective caesarean section should not be performed before that period.
