Abstract

This retrospective cohort study aimed to assess the frequency of emergency cesarean sections with epidural analgesia and its implications on Apgar scores and Neonatal Intensive Care Unit (NICU) admissions among patients at Tehran University of Medical Sciences Hospitals from 2017 to 2018. Data from 7170 patients were extracted from the hospital information system (HIS) through a consensus method. Descriptive statistics, cross-tabulation, and logistic regression analyses were conducted using Stata v17 software. Out of 9387 patients, 62.7% underwent cesarean sections, and 37.1% had normal vaginal deliveries. Epidural analgesia was administered to 127 patients, with 98.4% achieving successful normal vaginal delivery. Nulliparous women constituted 64.29% of those receiving epidural analgesia. Apgar scores at five and ten minutes were comparable between epidural and non-epidural groups. Emergency cesarean rates with epidural analgesia were low (1.6%). Findings align with previous research indicating no significant impact of epidural analgesia on Apgar scores. Nulliparous women predominated in the epidural group, consistent with pain pattern disparities. The study supports recent research showing epidural analgesia does not increase emergency cesarean rates, even in high-risk pregnancies. This study suggests that epidural analgesia does not significantly impact Apgar scores, NICU admissions, or emergency cesarean rates. While the comprehensive dataset enhances reliability, retrospective design limitations are acknowledged. Prospective studies exploring factors contributing to neonatal mortality and overall labor duration are recommended for more robust evidence. © 2023 Tehran University of Medical Sciences.
