Obstetric Outcomes of Vaginal Birth After Cesarean Section: A Case-Control Study

Abstract

10.30699/jambs.31.146.250 Background & Objective: Given the importance of the benefits of natural childbirth and the complications of recurrent cesarean section, we have conducted the present study to determine the maternal and neonatal complications of natural childbirth after cesarean section. Materials & Methods: In this case-control study, the obstetric complications of 84 women who had undergone a previous cesarean delivery referred to Baqiyatallah Hospital in 2018 for vaginal delivery after cesarean section (VBAC) delivery compared with 84 women with a previous vaginal delivery, who intended to give birth vaginally for the second delivery. Demographic, anthropometric, obstetric, and perinatal data of them were collected and registered in a researcher-developed form. Two groups were compared using the t-test and chi-square test. Results: The mean age in VBAC and control group was 30.49±6.83 and 32.08±7.28 years, respectively (P=0.15). There were not any occurrence of urinary rupture, bladder rupture, stool control disorder, uterine rupture, nephrotic infection, and ICU hospitalization of the mothers in the two groups. Regarding puerperal infection (3.57% in the VBAC group and 4.76% in the control group, P=0.69) and hospitalization of neonates in ICU (9.52% in the VBAC group and 5.95% in the control group, p=0.39), there was no significant difference between the two groups. Conclusion: It seems that the overall incidence of obstetric complications in women attempting vaginal birth after cesarean delivery is low and not higher than those with prior vaginal delivery. Therefore, for the achievement of benefits of natural childbirth for both the mother and the fetus, women with a prior cesarean should be offered VBAC.
