title: [The prospective study of trial labor following previous cesarean section].
abstract: OBJECTIVE
  To investigate the trial of labor following previous cesarean section.
  
  
  METHODS
  Three hundred and sixty one cases of pregnant women with history of previous low segment transverse cesarean section were prospectively studied on mode of delivery. 158 cases delivered by elective repeat cesarean section. 203 cases were allowed a trial of labor.
  
  
  RESULTS
  183 out of 203 patients had successful vaginal deliveries. One patient with uterine scar partly ruptured was noted on uterine exploration after delivery. There was no maternal death. The rate of spontaneous vaginal delivery was 79.2%. The rate of vacuum extractor and low forceps deliveries was 20.8%. The 1 minute Apgar score of 170 newborns was > or = 8. Neonatal asphyxia was found in 13 newborns and there was one neonatal death due to congenital abnormality.
  
  
  CONCLUSIONS
  Carefully selecting the indication of trial labor and monitoring the labor course are very important for increasing successful vaginal delivery rate and reducing repeat cesarean section.
