Abstract
Objective We set out to test the hypothesis that infants born vaginally at ≤ 30 weeks gestation have less respiratory distress syndrome (RDS) than those born by cesarean delivery.
Study Design We conducted a retrospective cohort study of 652 infants born between 24 and 30 6/7 weeks gestation from March 31, 1996 to May 31, 2014. Comparisons of neonatal outcomes by intended and actual mode of delivery were made using chi-square and t-tests (α = 0.05). Multiple logistic regression was performed to control for confounding variables.
Results Neonates born by cesarean delivery were more likely to have RDS (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.10–2.90), require intubation (OR, 1.80; 95% CI, 1.12–2.88), and have longer neonatal intensive care unit stay (70.0 ± 37.1 vs. 57.3 ± 40.1 days, p = 0.02).
Conclusion Compared with cesarean delivery, vaginal delivery is associated with a significant reduction in RDS among infants born at ≤ 30 weeks gestation.
