Abstract
This comprehensive review thoroughly examines the historical evolution, physiological foundations, and contemporary advancements in the application of phototherapy for neonatal hyperbilirubinemia. Neonatal hyperbilirubinemia, a common condition resulting from the immature hepatic processes in newborns, poses potential risks, including neurotoxicity, if left untreated. The review traces the historical progression from early recognition of neonatal jaundice to the development of various phototherapy modalities, showcasing the dynamic landscape of neonatal care. Emphasizing the physiological intricacies of bilirubin metabolism in neonates, the study underscores the vulnerability of newborns to hyperbilirubinemia due to delayed hepatic maturation. Phototherapy is a cornerstone in managing hyperbilirubinemia, demonstrating consistent efficacy in reducing unconjugated bilirubin levels. The implications for clinical practice are significant, offering healthcare professionals insights into tailoring treatment strategies based on individual neonatal characteristics and the severity of jaundice. Integrating advanced monitoring and control systems enhances the precision and safety of phototherapy. Recommendations for future research emphasize the need to investigate long-term outcomes, explore adjunctive therapies, and address resource limitations to ensure global access to effective neonatal care. Overall, this review contributes to the ongoing refinement of neonatal care practices, offering a comprehensive understanding of neonatal hyperbilirubinemia and its evolving treatment landscape.
