INTRODUCTION: Hyperbilirubinemia is one of the most common causes of health problems, observed in 60% of term and 80% of preterm infants in the first week of life. Hyperbilirubinemia leads to neurotoxicity in severe condition. Some studies suggests that liberal use of oxytocin for inducing labour is one of the factor which lead to neonatal hyperbilirubinemia.

OBJECTIVE: To compare the effect of oxytocin and neonatal bilirubin levels with spontaneous vaginal delivery.

MATERIALS AND METHODS: 100 full term parturients were selected for this study. The subjects were divided into two groups. 50 healthy babies of women who had oxytocin induced labour and 50 healthy babies of women with normal vaginal delivery following spontaneous onset of labour formed the control group. Neonatal serum bilirubin was measured on day 1, 3 and 5 after delivery. Bilirubin was measured by spectrophotometry. Data was analysed in ms excel sheet using spss 19.0v. Statistical analysis was done by using unpaired‘t’ test.

RESULTS: There was significant increase in bilirubin level in oxytocin induced group compared to control group on day 1 and 3. There was insignificant increase in bilirubin level in oxytocin induced group on day 5. However the level of serum bilirubin is within normal limits as bilirubin level normally rises on till 4th day and decreases thereafter.

CONCLUSION: Neonatal hyperbilirubinemia may be due to oxytocin administration by continues IV infusion which results in erythrocyte swell and rupture. Increase in bilirubin level in oxytocin induced group is within physiological limits.
