In a randomized control trial conducted in six study centers/labour wards in Sweden,
consenting nulliparous women in active phase of labour and with a defined delayed labour
progress will be randomized to receive a regimen of either high or low dose of oxytocin.
Primary outcome is caesarean delivery rate. Secondary outcomes are: Apgar score, need of
neonatal intensive care, hyper-stimulation of contractions, spontaneous vaginal birth rate,
length of labour, postpartum haemorrhage, sphincter lacerations, experienced labour pain,
epidural analgesia and the women´s childbirth experience one month postpartum (assessed with
Childbirth Experience Questionnaire). Study results will contribute to establish good
evidence-based routines regarding oxytocin treatment of delayed labour progress.
