[Vaginal birth after caesarean section in out-of-hospital settings: a literature review]

Even though vaginal birth after Caesarean section (VBAC) is recommended, an out-of-hospital setting is discussed controversially. First of all, uterine rupture and placental complications are named. Nevertheless, an increasing number of women with a prior Caesarean section decide to give birth in an out-of-hospital setting. What is the maternal and neonatal outcome in international studies in these cases?

The databases of Medline, Cinahl, Embase and Cochrane Library on vaginal birth after Caesarean section in out-of-hospital settings were searched. Included are studies in German and English language without a limit on year of publication, which describe maternal and neonatal outcomes.

5 studies were found. All of them describe a high VBAC rate (73.5-98%). Only one study found uterine ruptures. Haemorrhage/placental complications were described in 2 studies (0.5 and 1.7%). None of the studies found maternal deaths. Neonatal death was described in 3 studies in a range from 0 -1.7%.

There is a wide difference in the population of the studies. An important difference is the parity of the women and the prior mode of birth. 4 of the 5 studies do not see a reason not to try VBAC in an out-of-hospital setting. Further studies are necessary to inform the increasing number of women who decide to try VBAC in an out-of-hospital setting.
