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

Background: 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?

Method: 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.

Results: 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%.

Discussion: 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.
