Jardine JE, et al. - Considering the significance of acquiring accurate information about the risk associated with considering vaginal birth after cesarean (VBAC), researchers studied the cohort comprising 192,057 women who had a vaginal delivery of a singleton, term, cephalic infant in England (182,064 women who were having their first baby, and 9993 women who were having a second baby after a previous cesarean delivery) for their risk of an obstetric anal sphincter injury (OASI). Outcomes revealed a higher rate of OASI among women having a VBAC for their second baby following an emergency caesarean section in their first delivery than primiparous women. Women with a previous elective delivery had similar rates to those of primiparous women.
