ABSTRACT

Introduction: Hyperbilirubinemia(Jaundice) is common problem in neonates, is seen in about 60% of term neonates in first week and 80 % of preterm neonates. Phototherapy is the safest and commonly used treatment modality in neonatal jaundice. This study is aimed to measure the serum magnesium levels in neonates with hyperbilirubinemia before and after phototherapy to know the prevalence of phototherapy induced hypomagnesemia in term neonates. Methodology: This cross-sectional study was conducted on 100 term neonates with jaundice and receiving phototherapy, attending and admitted in Navodaya Medical College Hospital and Research Centre, Raichur. Study included full term neonates with unconjugated hyperbilirubinemia requiring phototherapy. Patient data was recorded in structured profoma. Serum bilirubuin level and magnesium level were sent before starting phototherapy and 48 hours after starting phototherapy. Results: There was statistically a significant difference in relation to magnesium level and ionized magnesium level before phototherapy and after phototherapy. No significant association was found between birth weight, postnatal age, mode of delivery, blood group incompatability and effect of phototherapy on s.magnesium level. Conclusion: The present study concludes that the phototherapy leads to a decrease in the levels of magnesium. The mean serum magnesium level reduced significantly after phototherapy in neonates with hyperbilirubinemia irrespective of age, sex, birth weight and mode of delivery. Phototherapy decreases bilirubin proportionately to IMg, implying that bilirubin and Mg levels in the blood have a positive relationship.
