According to the report, the evidence suggests that most patients who have had a low-transverse uterine incision from a previous cesarean delivery and who have no contraindications for vaginal birth are candidates for a trial of labor. Criteria for selecting candidates for VBAC include the following: (1) one previous low-transverse cesarean delivery; (2) clinically adequate pelvis; (3) no other uterine scars or previous rupture; (4) a physician immediately available throughout active labor who is capable of monitoring labor and performing an emergency cesarean delivery; and (5) the availability of anesthesia and personnel for emergency cesarean delivery..."
Summary:
The following recommendations are based on good and consistent scientific evidence (Strength of Recommendation Taxonomy [SORT] = A; see page 1201 for an explanation of SORT):
• Most women with one previous cesarean delivery with a low-transverse incision are candidates for VBAC and should be counseled about VBAC and offered a trial of labor.
• Epidural anesthesia may be used for VBAC.
The following recommendations are based on limited or inconsistent scientific evidence (SORT = B):
• Women with a vertical incision within the lower uterine segment that does not extend into the fundus are candidates for VBAC.
• The use of prostaglandins for cervical ripening or induction of labor in most women with a previous cesarean delivery should be discouraged.
The following recommendations are based primarily on consensus and expert opinion (SORT = C):
• Because uterine rupture may be catastrophic, VBAC should be attempted in institutions equipped to respond to emergencies with physicians immediately available to provide emergency care.
• After thorough counseling that weighs the individual benefits and risks of VBAC, the ultimate decision to attempt this procedure or undergo a repeat cesarean delivery should be made by the patient and her physician. This discussion should be documented in the medical record.
• Vaginal birth after a previous cesarean delivery is contraindicated in women with a previous classical uterine incision or extensive transfundal uterine surgery.
