Objective: To compare infant mortality rates among women with a failed versus successful trial of labor after cesarean (TOLAC) following labor induction or stimulation.
Study design: Using US linked birth and infant death cohort data (2000-2004), we identified women who delivered non-anomalous singleton births at 34-41 weeks with TOLAC whose labors were induced or stimulated. Multivariable log-binomial regression models were fitted to estimate the association between TOLAC success and infant mortality.
Results: Of the 164,113 women who underwent TOLAC, 41% were unsuccessful. After adjustment for potential confounding factors, a failed TOLAC was associated with a 1.4 fold (95% confidence interval [CI] 1.1, 1.7) increased risk of infant mortality.
Conclusions: Among women undergoing labor induction or stimulation, a failed TOLAC is associated with higher likelihood of infant mortality.
