[Peridural obstetrical analgesia and the cicatricial uterus. A 4-year evaluation]. / Analgésie péridurale obstétricale et utérus cicatriciel. Bilan de quatre années.

191 women with previous cesarean section in 291 indexed between October 1985 and September 1989 underwent a trial of labor. 146 patients received epidural analgesia in the course of labor. Vaginal delivery occurred in 126 patients (86.3%). Duration for epidural analgesia in labour was 163 +/- 110 min. The intrauterine pressure for monitoring continuous was 51.00 +/- 15.40 mmHg. We report four uterine dehiscences and one rupture. In no case, epidural analgesia did not delay the diagnosis. The use of epidural analgesia for trial of labor in previous cesarean section did not increase maternal or fetal risk.
