Studies show that over 95% of those who TOLAC will labor without scar problems, and will VBAC safely and successfully despite having factors that diminish their odds, including those with:
more than one prior cesarean
prior cesarean for labor dystocia
macrosomic baby (weighing 4000g or more)
advance maternal age
high body mass index (BMI)
longer pregnancy duration
single-layer uterine closure at the prior cesarean
thin scar
prior preterm cesarean
short interpregnancy/interdelivery interval
Rates of scar rupture depend heavily on labor management. Studies point towards scar ruptures often being caused by:
induction with an unripe cervix
induction using prostaglandin E2 (PGE2)
induction with misoprostol (now contraindicated)
high oxytocin dose
duration at high oxytocin dose
any other artificial augmentation of labor
Studies show that in the absence of labor-altering drugs, a uterine scar that has remained intact during pregnancy is very likely to remain intact through the birth
Did you know?
Studies and statistics show that scar rupture and VBAC success rates depend far more on the care provider than on the person or the scar
Uterine rupture rate is shown to be between 0.0%-3.8%, depending on the study cited, with the majority of studies showing rupture rates of 0.06%-0.7%, even with:
multiple cesareans
all forms of previous incisions
artificial induction
artificial augmentation of labor
VBAC decreases maternal mortality by 9 per 100,000 births over ERCD
With full informed consent, a healthy, responsible person can be given the choice to VBAC at home
