title: Evaluating trial of scar in patients with a history of caesarean section.
abstract: OBJECTIVE
  To analyze the outcome of trial of scar in patients with previous caesarean section and to assess the fetal and maternal complications after trial of scar.
  
  
  METHODS
  The study was conducted at Military Hospital, Rawalpindi, Pakistan, with 375 pregnant patients who had a previous delivery by caesarean and who had regular antenatal checkup. Data were recorded on special pro-forms designed for the purpose.
  
  
  RESULTS
  The results from the 375 patients who had one previous lower segment caesarean section due to non-recurrent causes were analyzed and compared with national and international studies. Indications of previous caesarean section (non-recurrent causes) included malpresentations, fetal distress/cord prolapse, failure to progress, severe pregnancy-induced hypertension/eclampsia and twins with abnormal lie of the first twin. 0 218 patients reported spontaneous labor. Among these patients, 176 delivered vaginally and 42 patients had repeat caesarean sections. There were a total of 157 patients who experienced induction of labor. 97 patients were induced by cervical ripening with mechanical method, followed by artificial rupture of membranes and augmentation (if required) with syntocinon infusion. 60 patients were induced with prostaglandin E(2) vaginal tablet.
  
  
  CONCLUSIONS
  This study concludes that females with a prior caesarean are at increased risk for subsequent caesareans, regardless of mode of delivery. Eliminating vaginal-birth-after-caesarean will not eliminate the risk. Therefore, vaginal birth after caesarean should be encouraged in selected cases from obstetric units to reduce the risks of repeated caesarean sections. Failed vaginal-birth-after-caesarean can result in increased morbidity than that with elective caesarean section.
