Cesarean vs. vaginal birth for term breech presentation in 2 different study periods.

OBJECTIVE: To compare outcomes for fetuses at term in breech presentation during 2 periods when different delivery policies were in effect. METHODS: Outcomes of the 392 planned vaginal deliveries and 1160 elective cesarean sections (CSs) performed from January 1, 1988, through December 31, 2000, were compared with those of the 24 emergency vaginal deliveries, the 403 planned CSs, and 75 emergency CSs performed from January 1, 2001 through December 31, 2004 at Alexandra Hospital, Athens, Greece. RESULTS: A significant difference was found in rates of low 5-minute Apgar score, birth trauma, serious neonatal morbidity, and admission to the neonatal intensive care unit (0% vs. 1.02% [P=0.004], 1.02% vs. 0% [P=0.004], 3.06% vs. 0.43% [P<0.001], and 2.8% vs. 0.43% [P<0.001], respectively) between neonates born by planned vaginal delivery and those born by elective CS during the first period. Only a reduction in rates of admission to the neonatal intermediate care unit was found between the first and second periods. CONCLUSIONS: Planned CS was found to be safer than planned vaginal delivery for fetuses at term in breech presentation. However, the study did not demonstrate that the change in policy improved neonatal outcome.
