Abstract Objective To guide the clinical management of birth process of cesarean delivery after cesarean section to improve the safety of TOLAC, it focuses on the labor course of vaginal delivery after cesarean section. Methods A retrospective analysis was conducted on the maternal births delivered at the Maternal and Child Health Hospital of Yangzhou from January 2016 and July 2017: vaginal birth after cesarean section (VBAC), and no previous cesarean section 30 cases were VBAC group. 30 cases of vaginal delivery of non-scarring uterus during the same period were selected as the maternal group and 30 cases of primipara. The three groups were all natural labor, labor without oxytocin and artificial rupture of membranes and other interventions. The total production process, the first stage of labor, the second stage of labor, the third stage of labor were compared among three groups, postpartum hemorrhage and neonatal score were also compared. Results The total length of labor in the VBAC group was significantly shorter than that in the primipara group (P < 0.01), but there was no significant difference between the VBAC group and the multipara group (P > 0.05). The duration of the second stage of labor was significantly longer than that of the multipara group (P < 0.01). There was no significant difference between the VBAC group and the primipara group (P > 0.05). There was no significant difference in the third stage of labor between the three groups. Postpartum hemorrhage, neonatal Apgar score difference was not statistically significant (P > 0.05). Conclusion The clinical manifestations of the first stage labor of VBAC are similar to those of non-scarred vaginal delivery. The normal fetal heart rate allows for full vaginal trial. The second stage of labor of VBAC is similar to that of primipara and requires more patient observation of the second Labor. It is conducive to improving vaginal delivery rate after cesarean section, but large sample studies are necessary
