title: Conjugated hyperbilirubinemia in infants with erythroblastosis fetalis.
abstract: In an attempt to identify the incidence of conjugated hyperbilirubinemia in infants with erythroblastosis fetalis the records of 67 infants were reviewed. Twenty-two infants were found to have direct bilirubin concentrations greater than 1.0 mg./dl. Among 11 infants who underwent intrauterine exchange transfusion, nine (82%) had conjugated hyperbilirubinemia. Of the remaining 56 infants without the procedure, only 13 (23%) showed evidence of this complication. To predict infants at risk of developing conjugated hyperbilirubinemia, the ratio of hematocrit and total bilirubin concentration in cord blood (H/B ratio) was examined.
