Abstract

Abstract  in English, French

Background: Uterine rupture is an obstetric emergency associated with significant maternal and perinatal mortality and morbidity, especially in resource-constraint countries such as Nigeria.

Objective: To determine the incidence and feto-maternal outcome of uterine rupture in a Nigerian teaching hospital.

Methods: This was a retrospective review of all cases of uterine rupture managed over 21 years. The case notes of all affected women were retrieved, and information on sociodemographic and obstetric characteristics, clinical presentation, intraoperative findings, and fetal and maternal outcomes were extracted. Data were analyzed using SPSS version 23.0 and descriptive statistics were computed. Factors associated with maternal deaths secondary to rupture of the gravid uterus were determined using binary logistic regression analyses. Statistical significance was reported at P<0.05.

Results: There were 31,616 deliveries during the review period, out of which were 182 cases of uterine rupture giving an incidence of 5.76 per 1,000 deliveries. Most of the cases of uterine rupture (65.2%) were treated by uterine repair. Maternal and fetal deaths were recorded in 8.1% and 82.7% of cases respectively. Women aged at least 35 years (P=0.035), women who had laboured at home or traditional birth attendant's (TBA) place (P=0.002), women who had multiple sites rupture (P=0.049) and those who developed hypovolemic shock (P=0.002) were more likely to die from uterine rupture.

Conclusion: Ruptured uterus remains a significant cause of maternal and perinatal morbidity and mortality in Nigeria. Strategies for prevention include effective health education of the masses, the conduct of labour in a well-equipped health facility, and prompt referral of at-risk women.
