Objectives: To evaluate the cost-effectiveness of the new oxytocin regimes in the augmentation of labour and the effect on the maternal and fetal outcome. Design: Randomized controlled trial. Setting: Labour ward of Hospital Tengku Ampuan Afzan, Kuantan. Participants: 230 pregnant women in labour at term with obstetric indications for labour augmentation. Methods: The women were randomly assigned to receive new oxytocin regime of 5 units in 500 cc of D/Saline at titration of 5 dpm with increments of 5 dpm to a maximum of 60 dpm. Or, old oxytocin regime of 1/2/4 units with titration of 20/40/60 dpm for primips and half the dosage for multips.
Main outcome measures: Cost analysis, duration of labour, duration of augmentation, complication of labour, post partum hemorrhage (PPH), mode of delivery and perinatal outcome.
Results: There was no significant difference in the mean duration of labour (6.8 h vs 6.7 h ; p = 0.45) and mean augmentation time (3.86 h vs 4.0 h; p = 0.9) between the regimes studied There seemed to be higher incidence of caesarean section in the old oxytocin group (6.5% vs 24.7%; p = 0.001). There was no significant influence on the neonatal morbidity and mortality (p = 0.07). A moderate reduction of annual cost for augmentation of labour was noted (RM 962.34).
Conclusion: The results showed that the new oxytocin regime was more cost-effective without apparent increased in the maternal and fetal mortality and morbidity.
