What is NOT a negative predictor for TOLAC?

A low body mass index (BMI) is considered a neutral or even potentially positive predictor for a trial of labor after cesarean (TOLAC). In the context of TOLAC, BMI is less likely to impact the success of a vaginal delivery. High BMI, on the other hand, is often linked to increased risk of complications during delivery and can be a negative predictor.

In contrast, labor augmentation, the presence of preeclampsia (PreE), and having no previous spontaneous vaginal delivery (SVD) are all factors that can negatively influence the likelihood of a successful TOLAC. Labor augmentation can indicate concerns about labor progress, and preeclampsia can pose additional risks to both mother and baby during labor. Additionally, not having a history of successful vaginal deliveries may indicate a greater likelihood of complications in attempting labor, thereby acting as a negative predictor.

Understanding these distinctions in predicting TOLAC success can help in managing care and counseling patients effectively regarding their delivery options.
