ABSTRACT
BACKGROUND: Epidural analgesia (EA) is widely used during labor and frequently associated with maternal intrapartum fever, often prompting neonatal sepsis evaluations. Data from East Asia is scarce; we evaluated whether EA is associated with increased neonatal infection risk and related complications in a Taiwanese cohort.
METHODS: This retrospective cohort study included 2375 full-term, singleton vaginal deliveries at a tertiary medical center in Northern Taiwan from 2018 to 2021. Neonatal outcomes were compared between mothers who received EA and those who did not. Neonatal infection was operationalized as admission to the NICU for suspected infection, and prolonged antibiotic therapy (>48 h) was evaluated as a secondary outcome.
RESULTS: Neonates in the EA group had a slightly higher rate of NICU admission for suspected infection than non-EA infants (4.04% vs 2.81%; p = 0.157), but this difference was not statistically significant. Maternal intrapartum fever occurred significantly more often with EA (28.3% vs 11.4%; p < 0.001), whereas neonatal fever was rare and similar between groups (1.79% vs 1.58%), and only one infant had culture-confirmed infection. In the NICU subgroup (EA N = 63; non-EA N = 23), low Apgar scores and meconium aspiration occurred only in EA-exposed infants, but these rare events and neonatal fever were not independently associated with EA in exploratory Firth logistic regression. Stratified analyses instead suggested that maternal intrapartum fever, rather than EA exposure, was more closely linked to neonatal fever.
CONCLUSIONS: In this cohort, EA was associated with frequent precautionary neonatal sepsis evaluation without an increase in culture-confirmed infection. Potential residual confounding suggests that these findings should be interpreted as exploratory rather than causal. These findings highlight the need for cautious evaluation to prevent unnecessary antibiotic use in neonates.
