Epidural “users” were compared to “non-users”. Primary outcome was the mode of delivery: repeat in-labor cesarean or vaginal birth after cesarean (VBAC). Secondary outcomes were maternal/neonatal morbidities. Univariate/multivariate analyses for associations between epidural and mode of delivery were adjusted for significant covariates/mediators.</jats:p></jats:sec> <jats:sec id="j_jpm-2016-0382_s_997"> <jats:title id="d361208e8080">Results:</jats:title> <jats:p>Of a total of 105,471 births registered, 9464 (9.0%) were eligible for TOLAC; 7149 (75.5%) women consented to TOLAC, among which 4081 (57.1%) had epidural analgesia. The in labor cesarean rate was significantly lower for the epidural “users” 8.7% vs. “non-users” 11.8%, P&lt;0.0001, with a parallel increased rate of instrumental delivery. Uterine rupture rates were comparable: 0.4% and 0.29%, respectively (P=0.31). The adjusted multivariate model showed that epidural “users” were more likely to experience a VBAC, odds ratio (OR) 4.58 [3.67; 5.70]; P&lt;0.0001 with a similar rate of adverse maternal-neonatal outcomes.</jats:p></jats:sec> <jats:sec id="j_jpm-2016-0382_s_996"> <jats:title id="d361208e8088">Conclusion:</jats:title> <jats:p>Epidural analgesia at TOLAC may emerge as a safe and significant adjunct for VBAC.</jats:p></jats:sec>
