摘要
Background:Neonates with ABO hemolytic disease are at greater risk for developing significant hyperbilirubinemia.We aimed to determine whether sixth hour transcutaneous bilirubin(TcB)could predict such a risk.Methods:TcB measurements were obtained at the 6th hour of life in blood group A or B neonates born to blood group O,rhesus factor compatible mothers.Subsequent hyperbilirubinemia was monitored and considered significant if a neonate required phototherapy/exchange transfusion.The predictive role of sixth hour TcB was estimated.Results:Of 144 ABO incompatible neonates,41(OA,24;O-B,17)had significant hyperbilirubinemia.Mean sixth hour TcB was significantly higher among neonates who developed significant hyperbilirubinemia than those who did not(5.83±1.35 mg/dL vs.3.65±0.96 mg/dL,P<0.001).Sixth hour TcB value>4 mg/dL had the highest sensitivity of 93.5%and>6 mg/dL had the highest specifi city of 99%.Area under receiver operating characteristic curve was 0.898.Conclusion:Sixth hour TcB predicts subsequent significant hyperbilirubinemia in ABO incompatible neonates.
