VBAC
Pronunciation: VEE-back
Also written as: VBAC — Vaginal Birth After Cesarean
Vaginal birth after cesarean section, requiring special anesthetic considerations.
Full Definition
VBAC (Vaginal Birth After Cesarean) refers to vaginal delivery attempted by a woman who has previously undergone cesarean section. This clinical scenario requires heightened anesthetic vigilance due to the risk of uterine rupture, which can necessitate emergency cesarean delivery. Anesthetic planning for VBAC patients includes ensuring immediate availability of surgical anesthesia, often maintaining epidural access for rapid conversion to surgical anesthesia if needed. The anesthesiologist must balance providing adequate labor analgesia while maintaining the ability to detect signs of uterine rupture, though epidural analgesia does not mask rupture symptoms.
Usage
Usage note: Always spell out on first use in documents. Distinguish from TOLAC (Trial of Labor After Cesarean).
