Background : In neonates, high levels of total serum bilirubin (TSB) can cause severe and irreversible brain damages. Thus, prompt diagnosis and treatment of indirect hyperbilirubinemia is of great importance in this age group. Phototherapy and exchange blood transfusion are two major therapeutic strategies to prevent bilirubin-induced brain damage in neonates. The choice of therapy depends on the severity of hyperbilirubinemia, but phototherapy is the most frequently used treatment . Aim of the work: The aim of this study is to compare between the Super Light-Emitting Diode and Conventional Phototherapy in treatment of neonatal Jaundice. Subject and method:  Randomized controlled study were carried out at Zagazig university children's hospital on 28 neonate who were classified onto 2 groups .Both groups included preterm and full term neonates 14 subjected to conventional phototherapy and the other 14 subjected to super LED phototherapy . Results :super LED is more effective than conventional phototherapy as  mean TSB at admission on super LED was 18.5 mg/dl , after 6 hours from super LED phototherapy mean TSB became 15.5 mg/dl  35%  from initial value  and after 24 hours from phototherapy mean TSB became 10.93 mg/dl 50% of initial value After24 h of treatment and normalization of serum bilirubin occurs after30 hours.butmean TSB at admission on conventional phototherapy was 17 mg/dl , after 6 hours from conventional phototherapy mean TSB became 15,9 mg/dl ,and after 24 hours from phototherapy mean TSB became 13.,8 mg/dl and normalization of serum bilirubin occurs after 47,5 hours. Conclusion: Super LED phototherapy is more effective than conventional phototherapy devices as they can provide rapid reduction on high levels of hyperbillirubinemia .more time saving and less side effects.
