Outline of Final Research Achievements

In 1991, Kobe University proposed treatment criteria for hyperbilirubinemic newborns using total serum bilirubin and serum unbound bilirubin reference values. In the last decade, chronic bilirubin encephalopathy (kernicterus) has found to develop in preterm infants in Japan. First, we revised the criteria of phototherapy for preterm hyperbilirubinemic infants. Secondly, we performed a multicenter collaborative prospective cohort study to confirm if chronic bilirubin encephalopathy can be prevented by using the revised criteria. One hundred fifty preterm infants who were born <30 weeks of gestations were enrolled. The infants performed phototherapy were decreased and there were no infants developing chronic bilirubin encephalopathy.
