EBB 113 - The Evidence on VBAC

In this episode, I am excited to share the evidence on vaginal birth after Cesarean, or VBAC. We have received many requests at Evidence Based Birth to cover this topic, so I want to share with you the information on VBAC that I present in a class we teach in the EBB Higher Ed program.

In this podcast, I define some common terms related to VBAC and talk about the history of the procedure. By the end, you will have the facts on the prevalence and risk factors for uterine rupture, and you’ll understand some of the maternal, fetal, and newborn risks of VBAC, elective repeat Cesarean, and Cesarean birth after Cesarean.
