Background: The aim of the work was to study post-operative maternal morbidity and mortality after caesarean delivery and laparotomy for uterine failure, to describe the main causes and to analyze the risk factors.Methods: It was a descriptive, comparative and analytical study lasting 2 years with data collection in 2 phases, one of which was a retrospective study lasting one year from July 2018 to June 2019 and the other a prospective study also lasting one year, from July 2019 to June 2020. It concerned all pregnant women who had been caesarized or had had a laparotomy for uterine rupture with complications and those who had not developed any complications. The parameters studied were types of complications, risk factors and maternal mortality. The Chi-square test was used to compare the two populations with a significance level p=0.05.Results: During the study period, 6141 hospitalizations were recorded among which 5682 surgical procedures were performed, i.e. 92.52% of hospitalizations. Caesarean delivery accounted for 90.55% of surgical procedures and laparotomy for uterine rupture for 1.10%. The overall maternal post-operative morbidity rate was 7.60%. Post-operative anemia was by far the most common complication (75.76%) followed by infection (23.46%). The maternal death rate was 0.92% with a ratio of 409.97 maternal deaths per 100,000 live births and more than 2/3 of these deaths were due to caesarean delivery. Anemia and septic shock were the main causes of death. Factors related to this post-operative maternal morbidity were: age greater than or equal to 40 years, multi-parity, illiteracy, emergency obstetric evacuation, low socio-economic level, poor quality of prenatal follow-up and rupture of membranes before admission.Conclusion: In the emergency context concerning majority of our cesarean deliveries and the totality of uterine ruptures predispose the mother to high significant morbidity and mortality.
