    Abstract:
    A prospective study of 454 newborn babies with pathological hyperbilirubinemia revealed that in about one-third of cases (34.6%), no cause could be identified despite detailed investigations. Nearly three-fifth of infants (62.5%) had hyperbilirubinemia due to hemolytic causes. On the basis of four variables, i.e., peak serum bilirubin level, age of attaining the peak level, age of starting phototherapy and total duration of phototherapy, the cases of hyperbilirubinemia can be categorized into three groups: (a) Group I (mild) included non-hemolytic hyperbilirubinemia, i.e., idiopathic, bacterial infections, intrauterine infections and others, (b) Group II (moderate) comprised of hemolytic as well as non-hemolytic hyperbilirubinemia due to prematurity, administration of oxytocin, bruising/cephalhematoma, and (c) Group III (severe) comprised of hyperbilirubinemia due to hemolysis as a result of blood group incompatibility between the mother and the neonate and G-6-PD deficiency. Sixty six babies required exchange blood transfusion (EBT) and a total of 100 EBTs were performed. Most of the babies (80.3%) requiring exchange blood transfusion belonged to Group III. The most common cause of hemolytic hyperbilirubinemia needing exchange blood transfusion was Rh isoimmunization followed by G-6-PD deficiency and ABO isoimmunization. There was no death attributable to the procedure of exchange blood transfusion.
