For a pregnant woman who already has had one cesarean delivery, an undertaking vaginal delivery is more dangerous for the baby than a second cesarean section, according to a research study. The study showed that vaginal birth after a cesarean section (VBAC) also is more dangerous for the mother, dominant to the increased prospect of a ruptured uterus and such complexities as endometritis infection of the uterus and the need for transfusions.
The issue is decisive because of the debate about the overuse of cesarean sections, which reached 26 % of all births in 2002. The United States Public Health Service has been seeking a reduction in the rate of cesareans to 15%; and had set a goal that 37% of women who previously had had a cesarean section to try normal or vaginal delivery for the next child.
Recent study shows that the risk of adverse perinatal results is expanded with a test of labor after a prior cesarean delivery but also corroborate that the risk is still very cramped. The results showed that the rate of uterine rupture was 7/1000 among the mothers who were attempting vaginal delivery, compared with no uterine ruptures among the women who chose a second cesarean.
The researchers said the risk is significantly small but greater than that associated with elective repeated cesarean delivery.
