Indications for cesarean deliveries in Norway.

Abstract

The purpose of this study was to investigate the indications for cesarean deliveries in Norway, related to type of operation, parity, and gestational age. This was a prospective survey that used information provided by clinicians at 24 maternity units. Two thousand seven hundred seventy-eight cesarean deliveries were included, which represents 69.7% of all cesarean deliveries in Norway during the study period. The cesarean delivery rate varied by maternal and gestational age, parity, and hospital of delivery. Seven indications accounted for 77.7% of the operations: fetal stress (21.9%), failure to progress (20.7%), previous cesarean delivery (8.9%), breech presentation >or=34 weeks of gestation (8.4%), maternal request (7.6%), preeclampsia (6.2%) and failed induction (4.0%). Of the total deliveries, 64.3% were emergency operations. Accurate information about indications for cesarean deliveries in Norway has been obtained. Two thirds of all deliveries were emergency operations; the most important indications were fetal stress and failure to progress. In the elective cesarean delivery group, the two most important indications were previous cesarean delivery and maternal request.
