One delivery in eight in the UK is by caesarean section. Women who have had a previous caesarean section may approach a midwife in subsequent pregnancies because they want more control over their labour. Vaginal birth after caesarean section (VBAC) is a safe option for women with a lower segment scar. Factors associated with a favourable outcome include spontaneous labour and freedom of movement during labour. Factors hindering successful outcome include reduced mobility, use of oxytocin, and time limits set on progress of labour.
