Slow labour progress is common in nulliparous women and is associated with childbirth complications and negative birth experiences. Oxytocin augmentation is widely used to treat slow labour despite associated risks for the fetus. An ongoing debate concerns whether oxytocin should be administered directly or postponed after arrested labour. The overall aim is to study labour progress in healthy nulliparous women and to compare childbirth outcomes and experiences in women randomised to expectant versus early oxytocin augmentation for slow labour progress.
The hypothesis is that it is to early to start oxytocin treatment when labour progress has been slow for 2 to 3 hours in healthy women having their first baby and therefore beneficial for childbirth outcomes to postpone oxytocin for another 3 hours. In this randomised controlled trial nulliparous women with a normal pregnancy, spontaneous onset of active labor at term, and a cervical dilatation of 4 - 9 centimetres on admission to the delivery ward were included (n=2,072). All women whose labour did not progress after amniotomy (n=630) were randomly allocated either to labour augmentation by oxytocin infusion (Early oxytocin, n=314) or to postponement of oxytocin augmentation for another three hours (Expectant, n=316). One month postpartum the women received a postal questionnaire concerning their experiences of labour and birth. All participating women gave their informed consent. Maternal and neonatal outcomes like mode of delivery, postpartum haemorrhage, perinatal lacerations, low Apgar score, need of neonatal intensive care and maternal experiences of childbirth were compared between the randomised groups.
