Abstract

Background: neonatal hyperbilirubinemia is a common condition in the first few days of life (1) and it can be divided into: pathological and physiological and indirect (unconjugated) and direct (conjugated) hyperbilirubinemia. Objective: This paper aimed to evaluate the effect of different types of phototherapy on serum calcium of both preterm and full-term infants with indirect hyperbilirubinemia, in either supine or prone position. Methods: data were taken from 100 newborns candidate by divided them into two groups. Blue and white light phototherapy were equally used for different infants of both groups. Results: the results showed that 31% developed hypocalcemia, 20% preterm and 11% full term infants. 38% developed hypocalcemia, where among infants who received prophylactic phototherapy 24% developed hypocalcemia. 60% of infants who received extensive phototherapy developed hypocalcemia, where 27.7% of infants who managed with single phototherapy developed hypocalcemia. Seventeen of the infants who managed in prone position and 14 infants of those who received phototherapy in supine position developed hypocalcemia. Conclusion: all in all, 19 infants developed hypocalcemia under blue light and 12 received white light phototherapy. Phototherapy induced hypocalcemia in both full term and premature infants. In addition to the common practice of monitoring the total serum bilirubin and PCV in all newborns on phototherapy, it is important to monitor the total serum calcium on daily base.
