AbstractAim: The aim of the present study was to determine the effect of phototherapy on serum magnesium level in termneonates with hyperbilirubinemia.Material & methods: A prospective hospital‑based comparative study was conducted on 200 eligible neonatesadmitted in the Department of Neonatology, receiving phototherapy for the period of one year. informed consentwas obtained from the parents of the selected neonates. This study included 200 full‑term neonates who weresubjected to phototherapy for treating neonatal hyperbilirubinemia according to the guidelines of the AmericanAcademy of Pediatrics.Results: Our study included 200 full‑term neonates with jaundice who received phototherapy for treating neonatalindirect hyperbilirubinemia, comprising 130 (65%) males, and 70 (35%) females, with the mean gestational ageof 37 ± 0.8 weeks and mean postnatal age of 5.4 ± 1.3 days. There were 68 (34%) neonates delivered by normalvaginal delivery and 132 (66%) neonates delivered by cesarean section. Mean birth weight was 3.2 kg. Subjectshave a mean intrauterine age of 38.45 weeks and a jaundice onset age of 3.67 days. The mean difference ofjaundice onset age, intrauterine age, admission weight and mother’s age were not significant. Serum totalmagnesium level in single and double phototherapy decreases after treatment, but this decrease is significant onlyin the double phototherapy group (P = 0.032). In the intensive group, this parameter has slightly increased, whichis not statistically significant (P = 0.575). The serum total magnesium level and its changes were reported in threegroups before and after phototherapy. The serum magnesium level in new borns before treatment was normal inall three treatment groups. The status of each patient showed that single, double, and intensive phototherapygroups have magnesium content of more than 2.2 mg/dl, respectively.Conclusion: In the present study, the serum magnesium level showed a significant reduction only in the doublephototherapy method and remained in the normal range in the other two groups. On the other hand, in all threetreatment groups, the level of serum magnesium before the treatment was normal and did not increasesignificantly
