Abstract

Objectives The aim of the study was to determine the effect of phototherapy on serum calcium level in neonatal jaundice. Background Phototherapy plays a significant role in the treatment and prevention of hyperbilirubinemia in neonates. However, this treatment modality may result in the development of some complications such as induction of hypocalcemia. Patients and methods This study included 50 full-term neonates with jaundice (25 males and 25 females) who received phototherapy for treatment of neonatal indirect hyperbilirubinemia and 25 neonates (13 males and 12 females) complaining of exaggerated physiological hyperbilirubinemia taken as control not exposed to phototherapy. Serum calcium was checked before and 48 h after starting phototherapy. A comparative study was conducted between these groups to determine the effect of phototherapy on serum calcium level. Results In the neonates of the study group, the serum bilirubin level before phototherapy was 15.48 ± 1.94 mg/dl. However, the serum bilirubin level after phototherapy was 12.41 ± 2.10 mg/dl. There was highly statistically significant decrease of the serum bilirubin levels after phototherapy as compared with serum bilirubin levels before phototherapy in the study group (P < 0.001). With respect to the calcium level, the total serum calcium level before phototherapy was 9.36 ± 0.29 mg/dl, whereas the serum calcium level after phototherapy was 8.58 ± 0.76 mg/dl. There was highly statistically significant decrease of the serum calcium levels after phototherapy as compared with serum calcium levels before phototherapy in the study group. Conclusion Hypocalcemia is a common complication of phototherapy.
