Maternal and perinatal outcomes of uterine rupture in a tertiary care hospital: a cross-sectional study

Objective: The current study aims to evaluate the incidence, maternal and perinatal outcomes in cases presented with uterine rupture (UR) and to explore the differences in presentation, management and outcome of UR in patients with scarred versus unscarred uterus. Materials and methods: A cross-sectional study conducted in a tertiary care hospital over a period of 2 years. The study included all women diagnosed with UR and admitted to the emergency unit between January 2016 and December 2017. A structured questionnaire was used to collect the preoperative demographic and clinical data. An observation checklist was used for intraoperative findings and management. Postoperative data were collected about maternal and fetal outcomes. Data were analyzed using SPSS software. Qualitative variables were compared between groups using chi-square test while quantitative variables were compared using the Mann-Whitney test. Results: Sixty two women were diagnosed with uterine rupture (0.32% of all deliveries). The mean age of the included patients was 29.6 +/- 5.6 years while the mean parity was 3.0 +/- 1.8. Uterine repair was successful in 52 cases (83.9%). There were four (6.5%) maternal deaths and 42 (67.8%) perinatal deaths. Ten patients (16.1%) were transferred to the postoperative intensive care unit (ICU). Re-exploration was carried out in three cases. The most common complication of UR was disseminated intravascular coagulopathy (DIC) occurred in eight women (12.9%). Maternal and perinatal mortality were significantly higher in patients with unscarred uterus (p = .0001 and .026, respectively). Conclusions: The incidence of UR is 32/10,000 deliveries in our tertiary hospital. Rupture of unscarred uterus is associated with more maternal and fetal mortality. However, rupture of scarred uterus was more common due to the rising rate of cesarean sections.
