Abstract:
Emergency cesarean section risk factors of Robson 1, 2A, 3, 4A:Introduction: Cesarean section rates in Mongolia exceed WHO recommendations of 5–15%, reaching 27.6% nationally and 34.1% at the First Maternity Hospital between 2019–2023. C-sections, while life-saving, increase risks of hemorrhage, infection, uterine complications, and reduced maternal quality of life. This study aimed to analyze emergency C-sections by Robson classification and identify associated risk factors in groups 1, 2a, 3, and 4a.
Material and methods: A retrospective case-control study was conducted using 886 medical records (443 emergency C-sections and 443 vaginal deliveries) from 2021–2023. Data were analyzed with IBM SPSS 24.0, and binary logistic regression was used to calculate odds ratios (OR) with 95% confidence intervals (CI).
Results: Robson 2a was the most frequent category (43.8%), followed by 4a (25.7%), 1 (20.1%), and 3 (10.4%). Significant risk factors for emergency C-section included maternal age (p<0.001), early cervical dilation (<5 cm) at labor diagnosis (OR 3.54), abnormal CTG, pre-eclampsia, PROM, amniotomy, infertility, and malposition. Multivariate analysis showed PROM (aOR 14.66), amniotomy (aOR 6.85), fetal weight ≥4000 g (aOR 4.07), and maternal age (aOR 1.48) as key predictors.
Conclusions: Emergency C-sections were most common in Robson group 2a. Major contributing factors included PROM, amniotomy, maternal age, macrosomia, and abnormal labor patterns. Targeted interventions to manage these risk factors could reduce unnecessary emergency C-sections.
