Abstract

Vaginal birth after cesarean section (VBAC) is safe, cost effective, and the preferred obstetrical option for most parturients in health care settings which are equipped to manage intrapartum emergencies. Since 1981, cesarean sections have been the most frequently performed major surgical procedure in the United States. Approximately 1,000,000 cesarean deliveries are performed in the United States per year. The rate of cesarean birth has increased from 4.5% in 1965 to 24.7% in 1988. Approximately 36% of these cesarean sections are elective repeat cesarean sections. [In selected patients, 75% to 81 % of these repeat cesarean sections may achieve a vaginal delivery if encouraged to undergo a trial of vaginal birth after cesarean section.] The advantages, disadvantages, indications, and contraindications, of VBAC are described.
