RESUMEN
Uterine rupture is a threat during vaginal deliveries of women with uterine scars from previous caesarean deliveries or other surgery. Special prudence among this group has resulted in a rise of cesarean rates in developed countries but also in Africa. The lack of available data in this domain in our country led us to conduct this preliminary study, with the objectives of: determining the frequency of deliveries among these patients and of the complications associated with them; identifying some of the risk factors and assessing maternal and fetal prognosis. This should facilitate further studies to determine the management attitudes most appropriate to the realities of our health system. We conducted a cross-sectional study during the last six months of 1999 at the central maternity hospital in Bangui. We included in this study only women with previous caesarean scars giving birth again during the study period. We followed them from admission to the labour room until discharge, without intervening in their delivery. Structured questionnaires enabled us to collect data on clinical, social and demographic variables. We recorded 74 births, including one set of twins, among the 73 parturient subjects. Vaginal delivery occurred in 45 cases (60.8%), and caesarean in 29. Women with a single uterine scar gave birth by vaginal delivery significantly more often than they had caesareans. We recorded 7 cases of uterine rupture, most often associated with a birth interval less than 2 years. One uterine rupture led to the mother's death. Perinatal mortality was 10.8%: no newborn survived these uterine ruptures. Vaginal delivery remains possible for women with uterine scars when adequate monitoring of a trial of labor is available and on condition that the pelvis is normal and the birth interval exceeds two years.

Although now uncommon in developed countries, uterine rupture is among the major obstetrical emergencies dealt on a daily bases in the maternity ward of the Bangui Community Hospital in Central African Republic, which is the national reference facility. Uterine rupture is life-threatening for both the fetus and mother. In view of the relatively high rate of rupture observed in our department in previous years, this cross-sectional study was undertaken in order to determine incidence, identify predisposing factors, evaluate prognosis for the mother and newborn, and propose solutions. From January 1997 to December 1997, all deliveries by the vaginal route or cesarean section including cases involving uterine rupture were recorded. The length of time elapsed between the decision to perform cesarean section and actual performance of the procedure was determined. Risk factors associated with uterine rupture in our department were noted. The outcome of uterine rupture was evaluated in both the mother and fetus. Of a total of 5763 deliveries during the study period, 299 required cesarean section (5.9%). Uterine rupture occurred in 35 cases of the 299 women (11.7%). In 10 cases of uterine rupture, the time lapse for performance of cesarean section was at least 2 hours. The main cause of delay was the lack of funding for cesarean section. Six women died due to irreversible shock (0.1% of deliveries, 2% of cesarean sections and 17.1% of uterine ruptures). The perinatal mortality rate was 80%. In our department, uterine rupture is a common emergency causing high mortality in mothers and newborns. Most of these patients could have been saved.
