TOLAC
Pronunciation: TOH-lak
Also written as: TOLAC — trial of labor after cesarean
Trial of labor after cesarean; an attempt at vaginal delivery following a previous cesarean section.
Full Definition
Trial of labor after cesarean (TOLAC) refers to a planned attempt at vaginal delivery in a woman who has had a previous cesarean section delivery. This approach allows women the opportunity to experience vaginal birth after cesarean (VBAC) while acknowledging that emergency cesarean delivery may become necessary. TOLAC is considered appropriate for carefully selected candidates who meet specific criteria, including previous low transverse uterine incision, absence of contraindications to vaginal delivery, and availability of immediate surgical facilities. Success rates vary based on individual factors, and continuous monitoring is essential during labor to detect potential complications such as uterine rupture.
Usage
Usage note: Distinguish from VBAC, which refers to successful vaginal delivery outcome.
