“…Multiple logistic regression analysis showed that induction of labor was positively associated with TOLAC failure. Cohort studies conducted in India and Israel also showed that labor induction was independently associated with failed TOLAC [9,15,23]. The rate of IOL was also higher (16.7%) in the VBAC group in Caroline' study [18].…”

Objective To evaluate the outcomes and risk factors for trial of labor after cesarean delivery (TOLAC) failure in patients in China. Methods Consecutive patients who had a previous cesarean delivery (CD) and attempted TOLAC were included from 2014 to 2020. Patients who successfully delivered were classified into the TOLAC success group. Patients who attempted TOLAC but had a repeat CD due to medical issues were classified into the TOLAC failure group. Multiple logistic regression analyses were performed to examine the risk factors for TOLAC failure. Results In total, 720 women who had a previous CD and attempted TOLAC were identified and included. The success rate of TOLAC was 84.2%(606/720). Seven patients were diagnosed with uterine rupture, none of whom underwent hysterectomy. Multiple logistic regression analysis showed that the induction of labor (OR = 2.843, 95% CI: 1.571–5.145, P < 0.001) was positively associated with TOLAC failure, but the thickness of the lower uterine segment (LUS) (OR = 0.215, 95% CI: 0.103–0.448, P < 0.001) was negatively associated with TOLAC failure. Conclusions This study suggested that TOLAC was effective in decreasing CD rates in the Chinese population. The induction of labor was positively associated with TOLAC failure, but the thickness of the LUS was negatively associated with TOLAC failure. Our findings need to be confirmed in larger samples with patients of different ethnicities.

“…A large number of predictive models of trial of labor after cesarean delivery have been reported in China and abroad 11,13,15,22,25–28 . However, most studies were based on maternal obstetric characteristics, and some only combined fetal birth weight or estimated fetal weight near term.…”

“…A large number of predictive models of trial of labor after cesarean delivery have been reported in China and abroad. 11,13,15,22,[25][26][27][28] However, most studies were based on maternal obstetric character- fetal head circumference obtained from ultrasound. Some scholars have established a prediction model for the success rate of VBAC, including several more typical models, such as the Grobman nomogram, 11 Smith, 21 and Gonen 29 models.…”

ObjectiveThis study aimed to develop and validate a prediction model of vaginal birth after cesarean delivery (VBAC) in China.MethodsA nomogram for effective prediction of VBAC of singleton, cephalic and one previous low‐transverse cesarean section deliveries was created by comparing the combinations of ultrasonographic and non‐ultrasonographic factors from five hospitals between 2018 and 2019.ResultsA total of 1066 women were included. Of the women who underwent trial of labor after cesarean (TOLAC), 854 (80.1%) had a VBAC. Ultrasound factors included reached a higher area under the curve (AUC) combined with non‐ultrasonographic factors. Of the three ultrasonographic factors analyzed, the best predictive factor for successful TOLAC was fetal abdominal circumference. A nomogram was generated with eight validated factors, including maternal age, gestational week, height, previous vaginal delivery, Bishop score, dilatation of the cervix at the time of admission, body mass index at delivery, and fetal abdominal circumference by ultrasound. The trained and validated AUC were 0.719 (95% confident interval 0.674–0.764) and 0.774 (95% confident interval 0.712–0.837), respectively.ConclusionOur VBAC nomogram based on obstetric factors and fetal abdominal circumference obtained by ultrasound could be used to counsel women who are considering TOLAC.
