OBJECTIVE: To investigate the relationship of neonatal bilirubin levels to oxytocin infusion and the diluent used for oxytocin infusion.

MATERIALS AND METHODS: The study was carried out as a prospective, randomized study in Istanbul University Cerrahpasa School of Medicine, Department of Obstetrics and Gynecology between January to December in 1995. A total of 80 patients managed with oxytocin during labor, enrolled to the study. These patients randomly divided into isotonic % 0.9 saline (Group 1) and 5% glucose solutions (Group 2) by a consecutive order using a balanced block randomization scheme. Forty multiparous patients delivering without oxytocin infusion formed the control group (Group 3). The details of maternal age, gestational age, labor duration, mode of delivery, birth weight of the babies, total volume of fluid administered until delivery and total oxytocin dose were noted in each case. Sodium and initial bilirubin levels were measured in the cord blood. Later on, capillary blood bilirubin and hematocrit concentrations were measured on day 1 and 2 in the newborn nursery. The groups were compared according to these parameters.

RESULTS: The data of 29 patients in Group 1, 36 patients in Group 2 and 40 patients in Group 3 were suitable for analysis. The difference between study and control groups regarding the rate of hyponatremia, neonatal hyperbilirubinemia and neonatal jaundice was not statistically significant. Cord plasma sodium levels, cord plasma bilirubin levels and day 1 and 2 hematocrit and plasma bilirubin levels were not statistically different between the groups. irrespective of the diluent used, the cord plasma bilirubin levels and day 2 plasma bilirubin levels were significantly higher in the accelerated group.

CONCLUSION: No significant effect of oxytocin infusion was revealed on neonatal hyperbilirubinemia unless oxytocin was for the augmentation of labor.
