Vaginal delivery in Nigerian women after a previous cesarean section.
A total of 154 consecutive Nigerian women at term pregnancy who had undergone one previous cesarean delivery were prospectively studied during the year March 1987 to February 1988. A repeat elective cesarean section was performed in 52 (33.8%) patients. Vaginal delivery was achieved in 73 (71.6%) of the 102 subjects who were allowed into labor, and in over 90% of the comparison group. High vaginal delivery rates occurred among the women within the selection criteria irrespective of the indication for the previous cesarean section. A repeat emergency cesarean section was performed in 29 (24.5%) women. Rupture of the uterine scar occurred in 5 (4.9%) instances with the loss of 2 babies; there was no maternal loss. Excluding the high incidence of fetal asphyxia and uterine rupture which occurred among women in the study group, maternal morbidity and perinatal mortality and morbidity were similar to those of the comparison group. There was a statistically significant difference between the study and comparison group. There was a statistically significant difference between the study and comparison groups with regard to the mode of delivery. Among the study group, a significant correlation existed between the vaginal delivery rate of the patients and the indication for the primary cesarean section. There was however, no significant difference between the mean parities of the women who were delivered by cesarean section and those who delivered vaginally. Similarly, no significant difference existed in the mean birthweights of the babies delivered vaginally and those who were delivered abdominally during labor.(ABSTRACT TRUNCATED AT 250 WORDS)
