Phototherapy in full-term infants with hemolytic disease secondary to ABO incompatibility

Current guidelines for treatment of hemolytic disease of the newborn make no differentiation between ABO and Rh incompatibility. A protocol that prolonged the observation period in full-term, ABO-incompatible infants with positive Coombs' tests who were otherwise healthy was tested. Postponement of treatment made it possible to determine more accurately which infants needed phototherapy. This dramatically decreased the number of infants treated without increasing their risk of requiring exchange transfusion.
