Management of pregnancy after cesarean section.

Management of 226 patients with previous low transverse cesarean section in a special obstetric clinic for high-risk pregnancies significantly and safely reduced the incidence of purely elective cesarean section to less than 10%. A substantial incidence (25%) of other high-risk factors dictating antepartum indicated cesarean section were found in this population. There was 38.5% incidence of vaginal delivery in 145 patients who underwent a trial of labor. Patients delivered vaginally followed a normal labor curve up to full dilatation. Oxytocin was required in three cases of prolonged second stage of labor and resulted in instrumental vaginal delivery in all instances. There were no uterine ruptures on vaginal exploration after delivery or at the time of repeat cesarean section during labor. There was no maternal death or perinatal loss. No justification for the present clinical practice of a 99% inicidence of elective repeat cesarean section could be found. Substantial savings in hospital cost, as well as a decreased number of diagnostic tests for the otherwise normal gravid woman, can be safely achieved.
