Purpose
To clarify whether an increased cesarean section rate improves the short-term neonatal outcome in singleton term pregnancies with cephalic presentation.
Methods
A retrospective study of institutional data on the mode of delivery and neonatal outcome. The study included two cohorts: 1998–1999 (n = 7437) and 2004–2005 (n = 8505), since the institutional cesarean section rate increased sharply between these cohorts and has remained stable after the latter study period.
Results
The caesarean section rate almost doubled from 6.8 to 11.3 % (p < 0.001), during the study period. The rate of neonates suffering severe birth asphyxia remained low in both cohorts (0.4 vs. 0.6 %) and there were no significant differences in neonatal outcome (Apgar score <4 at 1 min and Apgar score <7 at 5 min, severe birth asphyxia, resuscitation or artificial ventilation) between the study periods. In the subgroup of neonates delivered vaginally, no significant differences were found in the above-mentioned neonatal outcomes between the cohorts. Apart from other outcomes admissions to neonatal intensive care unit increased significantly (p < 0.001) during the latter period (0.8 vs 1.6 %).
Conclusions
Increasing cesarean section rate from a low to a moderate does not improve the short-term neonatal outcome in term singleton pregnancies. On the contrary neonatal intensive care unit admissions increased with increasing caesarean section rate. Furthermore it is possible to achieve good neonatal outcome with a low cesarean section rate.
