Forgoing Exchange Transfusion in Neonatal Hyperbilirubinemia: A Single-Center Retrospective Cohort Study.

ABSTRACT

INTRODUCTION: Unconjugated hyperbilirubinemia is part of the everyday life of the neonatal period as it reflects the adaptation of the metabolism of bilirubin. The neonatal hyperbilirubinemia usually resolves spontaneously, but it can also be the cause of an acute or chronic encephalopathy known as kernicterus. Regardless of the cause, the goal of therapy is to prevent this neurotoxicity while not causing undue harm. Phototherapy and, if it is unsuccessful, exchange transfusion (ECT) remain the primary treatment modalities used to keep the maximal total serum bilirubin (TSB) below pathologic levels. MATERIALS AND METHODS: This is a descriptive retrospective cohort study of 69 live neonates hospitalized in the Department of Neonatology and Neonatal Resuscitation of Mohammed VI University Hospital with unconjugated hyperbilirubinemia requiring ECT and treated with intensive phototherapy instead, spanning five years from March 2016 to March 2021. We aim to demonstrate the effectiveness of phototherapy in achieving prolonged reduction of bilirubin levels and the prevention of neurological complications and to compare our results with those in the literature. RESULTS: The use of intensive phototherapy in the treatment of neonatal unconjugated hyperbilirubinemia is very effective in lowering total serum bilirubin when its level is in the range of exchange transfusion, and it has succeeded in preventing the neurological complications of severe hyperbilirubinemia. CONCLUSION: Through this study, it can be seen that phototherapy is an efficacious, simpler, and less hazardous alternative to exchange transfusion in achieving a sustained reduction of bilirubin levels and preventing neurological complications.
