Cesarean birth: how to reduce the rate.

The cesarean section rate, which approached 25%, has stabilized and started a modest decline. A stated United States national goal by the year 2000 is a rate of 15%. Suggested rates are 12% for primary and 3% for repeat cesarean sections. The major indications for cesarean section are prior cesarean delivery (8%), dystocia (7%), breech presentation (4%), fetal distress (2% to 3%), and others. The major areas of reduction must occur in the categories of prior cesarean delivery and dystocia. An expanded use of trial of labor and vaginal birth after a prior cesarean section will produce further reductions. Countries in Europe achieve > 50% vaginal birth after a prior cesarean section compared with 25% in the United States. A heightened awareness must occur regarding the decision to perform the first cesarean section. The residual impact, a scarred uterus, affects 12% to 14% of women seen for delivery. Even if 50% achieve a vaginal birth after a prior cesarean section, the national goals are unachievable. The obstetrician must consciously consider the impact of "once a cesarean, always a scar."
