Abstract
OBJECTIVE: To assess the utility of 24 and 48 hours transcutaneous bilirubin (TcB) index for predicting subsequent significant hyperbilirubinemia in healthy term neonates.
METHODS: TcB indices were obtained for healthy, breastfed, term AGA newborns at 24 +/- 2, 48 +/- 2 and subsequently at intervals of 24 hours. Neonates with illness, on treatment and positive Direct Coomb's test were excluded. Serum bilirubin levels were obtained whenever indicated. Neonates having serum bilirubin > or = 17 mg/dL were considered as significant hyperbilirubinemia. The 24 and 48 hour TcB indices, as risk predictors for such hyperbilirubinemia were determined.
RESULTS: Study included 461 healthy term neonates. The mean birth weight was 2949 (+/- 390) gm and mean gestation of 38.6 (+/- 1.1) weeks. Eight one (17.6%) had significant hyperbilirubinemia. Of 461, 135 (29.3%) had TcB index.
CONCLUSION: The 24 and 48 hour TcB indices are predictive for subsequent significant hyperbilirubinemia and can guide clinician in early discharge of healthy term newborns.
