The present study examined the relation between the timing of elective cesarean delivery at term and neonatal respiratory outcomes at our institution. From 2005 through 2013, 1,951 elective cesarean singleton deliveries were performed at term. Of the neonates, 141 (7%) had respiratory disorders requiring oxygen supplementation. In comparison to the incidence of respiratory disorders in neonates delivered at full term (39-40 weeks), the incidences in neonates delivered at ≤38+1/7 weeks' and at 41 weeks' gestation were significantly higher. Uncomplicated elective cesarean singleton delivery should be avoided at 38+1 weeks or earlier, and we also pay attention to the respiratory outcomes of neonates delivered by elective cesarean section at 41 weeks' gestation.
