Summary
Trial of labor after cesarean delivery is a viable option, with low rates of uterine rupture. Careful fetal monitoring is crucial for preventing perinatal deaths during labor after cesarean.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Surgical Outcomes
Background:
- The 'once a section, always a section' approach is common due to fears of uterine rupture.
- Vaginal birth after cesarean (VBAC) is an alternative delivery method for selected patients.
Purpose of the Study:
- To evaluate the safety and outcomes of trial of labor (TOL) in patients with previous cesarean sections.
- To compare the incidence of uterine rupture and scar dehiscence between TOL and elective repeat cesarean sections.
Main Methods:
- Retrospective analysis of 1498 patients with prior cesarean sections.
- Delivery outcomes were categorized into trial of labor (TOL) and elective repeat cesarean section.
- Incidence of uterine rupture, scar dehiscence, and perinatal outcomes were recorded.
Main Results:
- Eight true uterine ruptures and 22 scar dehiscences occurred among 1498 deliveries.
- The rate of true rupture in the TOL group was 1:169.
- Four perinatal deaths were associated with true rupture; fetal compromise detection was a key factor.
- No maternal deaths occurred in the TOL group, compared to one in the elective section group.
Conclusions:
- Trial of labor is a safe option for many women with previous cesarean sections.
- Uterine rupture rates are low, and fetal monitoring is critical for successful TOL outcomes.
- The 'once a section, always a section' policy may be overly cautious for a significant number of patients.
