Incidence of phototherapy induced hypocalcemia in full term normal newborn

Saravanan. S and Raghuram. A.S

Background: Neonatal hyperbilirubinemia is one of the most prevalent clinical problem occurring in the neonatal period. Phototherapy is the most commonly used treatment modality with its inherent complications. However, this treatment modality itself may result in hypocalcaemia and create serious complications including convulsion and related conditions.
Objective: To determine the effect of phototherapy on serum calcium level in full-term hyper bilirubinemic neonates.
Materials and Methods: This study was performed on 198 full-term jaundiced neonates (113 females and 85 males) receiving phototherapy. These neonates had complete normal physical examination other than hyper bilirbinemia. Plasma bilirubin and calcium levels were determined before and after 48 hours of phototherapy.
Conclusion: Although phototherapy lowers serum calcium level in term infants, but the incidence of phototherapy-associated hypocalcaemia is not too much.
