Final answer:
VBAC (vaginal birth after cesarean) success rates can be influenced by factors such as previous vaginal birth, malpresentation, fetal distress, and induction with prostaglandin.
Step-by-step explanation:
Vaginal birth after cesarean (VBAC) is a procedure in which a woman gives birth vaginally after having previously had a cesarean section. The overall success rate of VBAC can be influenced by several factors:
- Previous vaginal birth: Women who have previously given birth vaginally have a higher success rate for VBAC compared to those who have not.
- Malpresentation: If the baby is in a breech or other abnormal position, it may reduce the chances of a successful VBAC.
- Fetal distress: If the baby is in distress or experiencing complications during labor, a VBAC may not be possible.
- Induction with prostaglandin (PG): Inducing labor with prostaglandin can increase the risk of uterine rupture in women attempting a VBAC, but it can be used if the benefits outweigh the risks.
