Effect of Phototherapy on Serum Electrolyte Levels

Abstract

Objective: This study aimed to investigate the effect of phototherapy on serum electrolyte levels in neonates admitted to neonatal intensive care unit with the diagnosis of neonatal hyperbilirubinemia.Methods: Demographic profiles, laboratory findings, and electrolyte levels before phototherapy and 48-72 hours after phototherapy of260 patients hospitalized with neonatal hyperbilirubinemia between June 2016 and June 2018 were compared in this retrospective study.Results: The mean sodium level significantly decreased from 140.5 mg/dL to 139.1 mg/dL after phototherapy. The decrease in potassiumlevel was not statistically significant. The mean calcium level significantly decreased from 9.98 mg/dL to 9.55 mg/dL. The mean chloridelevel before phototherapy significantly decreased from 106.4 mmol/L to 105.9 mmol/L after phototherapy.Conclusion: The level of serum electrolytes in newborns may change with phototherapy. Serum sodium, chloride, and calcium levelsmay decrease after phototherapy. For prevention of possible adverse effects, the changes in electrolyte levels should be considered in theclinical course of newborns receiving phototherapy and appropriate fluid-electrolyte treatments should be given.

Özet

Amaç: Sarılık tanısıyla yenidoğan yoğun bakıma yatırılmış yenidoğanlarda fototerapinin serum elektrolit düzeyleri üzerine etkisinin araştırılması amaçlanmıştır. Yöntemler: Haziran 2016 ve Haziran 2018 tarihleri arasında sarılık tanısıyla hastaneye yatırılan 260 hastanın, fototerapi öncesinde ve 48-72 saat sonrasında bakılan kan tetkiklerindeki elektrolit düzeyleri retrospektif olarak karşılaştırılmıştır. Bulgular: Fototerapi öncesinde sodyum değeri fototerapi sonrasında ortalama 140,5 mmol/L’den 139,1 mmol/L’ye düşmüştür (p
