- Introduction: Delay in labour due to ineffective uterine contractions is a major problem in obstetric care and a main reason for the increased rate of caesarean deliveries, particularly among nulliparous women. Infusion with synthetic oxytocin is a commonly used treatment of hypotonic uterine contractions however there is a gap of knowledge concerning which dosage of oxytocin should be used, both starting dose and increment dose of oxytocin. Aim of the study: The aim is to compare starting dose and increment of amount of oxytocin for augmentation of delayed labour to determine whether augmentation by high dose of oxytocin improves labour outcomes compared with a low dose of oxytocin, without affecting neonatal or maternal outcomes including birth experiences negatively. Research methodology: In a randomized double-blind controlled trial conducted in three labour wards in Sweden, consenting nulliparous women in active labour and with a defined delayed progress are randomized to receive a regimen of either high dose or low dose of oxytocin (33.2 respectively 16,6 microgram oxytocin in 1000 ml isotone saline solution). randomization will be computer-generated, with allocation concealment by a coding system. Primary outcome is caesarean delivery rate. Based on a sample size calculation (α=0.05, β=0.80), a minimum of 688 women will be included in each group in order to reduce caesarean section rate from 17.5 % to 12 %. Ethical approval: The study is approved by the regional Ethics Board in Gothenburg (dnr: 090-12), and by the medical Products Agency –Sweden (Eudra-CTnr:2012-000356-33). Study finding: This poster will describe the study protocol and the first period of data collection. Results will concern: 1) maternal and fetal outcomes in randomized groups, and 2) maternal overall childbirth experience including labour pain. Conclusion: The study will contribute to establishment of evidencebased routines regarding oxytocin treatment of delayed labour progress.
