Abstract：
:Total cesarean section rates and rates of various indications for primary cesarean section were reviewed for four yearly periods during the past decade. The time periods studied were chosen to follow the introduction of new obstetric practices and technologic advances in monitoring fetal condition. The total cesarean section rate increased from 6.8% to 17.1% during this time. The most common indication for primary cesarean section was cephalopelvic disproportion, which represented approximately 40% of cases during each study period. Primary cesarean section for fetal distress increased to 28.2% but has decreased over the past 2 years to a present rate of 11.7%. Primary cesarean section for breech presentation increased from 12.3% to 21%. From the perspective of this review a total cesarean section rate of 15% is predicted for the future.
