Trial of Labour

The declining rate of vaginal birth after a cesarean (VBAC) means that repeat cesareans are increasingly important contributors to rising cesarean rates. A trial of labour refers to planned labour versus scheduled cesarean.  In B.C., over half of the women eligible* for a VBAC are not being offered a trial of labour.

*Perinatal Services BC describes women as ‘eligible’ for a VBAC if they have the following characteristics: term pregnancy (at least 37 weeks gestation); single baby; and cephalic presentation at delivery. [Source: Perinatal Health Report 2008, p78]
