I was most interested in the paper by Dr. Waters in Pediatrics, 33:749, 1964.
Dr. Waters has presented cogent reasons for not doing an exchange transfusion for a bilirubin of 20 mg/100 ml. I should like to refer to an earlier paper by Dr. Byers (Pediatrics 1955, 15:248), in which 23 patients are presented with cerebral palsy and hearing loss following erythroblastosis. Dr. Byers states in this paper that only 2 of the 23 patients had clinically recognized kernicterus in the newborn. It is not always easy to be certain that our jaundiced newborns are not going to develop later complications. The PSP binding technique offers some promise in this regard.
