Key Takeaway

Consider local constraints when applying standard neonatal hyperbilirubinemia guidelines in high-altitude regions.

This systematic review addresses the management of neonatal hyperbilirubinemia specifically within high-altitude regions, particularly in China and among high-altitude ethnic minority populations. The scope encompasses the application of rapid detection technologies and specific intervention strategies in these unique environments. The authors note that studies on the prevalence and associated factors of neonatal hyperbilirubinemia have remained controversial due to significant influences from cultural, demographic, geographic, climatic, and clinical conditions.

The review identifies that implementing World Health Organization recommendations proves particularly challenging in China, especially in high-altitude ethnic minority areas. Key constraints include a harsh environment, regional economic deprivation, insufficient investment in medical resources, and risks associated with genetic variations. These factors complicate the standardization of care and the adoption of universal protocols in these specific geographic locations.

The authors provide evidence-based guidance and practical recommendations for clinical practitioners navigating these complex settings. However, the review acknowledges that the existing literature is limited by the heterogeneity of the conditions studied. Consequently, the synthesized conclusions must be interpreted with caution, recognizing that the evidence does not support a single, uniform approach for all high-altitude scenarios.

High-altitude neonatal hyperbilirubinemia refers to a common condition in newborns residing at elevations of 2,500 meters or higher. This condition arises from the combination of high-altitude environmental factors—such as hypoxia and low atmospheric pressure—with physiological characteristics specific to newborns, including immature bilirubin metabolism and increased red blood cell destruction. These factors collectively lead to abnormally elevated serum bilirubin levels. However, studies on the prevalence and associated factors of neonatal hyperbilirubinemia have remained controversial due to influences from cultural, demographic, geographic, climatic, and clinical conditions. The World Health Organization recommends a one-day hospital stay after uncomplicated delivery, jaundice assessment prior to discharge, and screening for hyperbilirubinemia on the third and seventh days after birth. Due to constraints such as the harsh environment of plateau regions, regional economic deprivation, insufficient investment in medical resources, and risks associated with genetic variations among populations, implementing these recommendations proves particularly challenging in China, especially in high-altitude ethnic minority areas. Therefore, medical laboratory technology plays a pivotal role in the early screening, diagnosis, and treatment efficacy assessment of neonatal hyperbilirubinemia in high-altitude regions. This systematic review summarizes recent advances in the epidemiological characteristics, etiological mechanisms, diagnostic strategies, and therapeutic interventions for neonatal hyperbilirubinemia in high-altitude regions. It also examines the application value of rapid detection technologies and specific intervention strategies in plateau areas. Finally, it outlines future research directions, providing evidence-based guidance and practical recommendations for clinical practitioners.
