RESUMEN
A retrospective study to determine the risks of normal delivery after cesarean section, was done. The inclusion criteria were found in 116 patients in six years covering the study. All the patients were permitted normal delivery and none received ocitocin. Sixty six patients accomplished delivery, which corresponds to 57%. In the rest of patients cesarean section was performed. The probability of ending in delivery was associated to women with three or more gestas. But cephalo-pelvic disproportion and fetal suffering, were associated to greater probability of ending in cesarean section. There was no dehiscence of uterine scar. It is concluded that with well established requisites it is possible to resolve by delivery with a great degree of confidence, at least 50% of cases with previous section.
