Optimizing fever management in pediatric emergency medicine: pathophysiology, diagnostics, and evidence-based strategies

Abstract

Fever is a prevalent clinical manifestation in pediatrics, representing a significant proportion of emergency department (ED) visits worldwide. While fever is often benign and self-limiting, it can also indicate life-threatening infections requiring immediate intervention, particularly in neonates and immunocompromised children. This comprehensive review delves into the intricate pathophysiology of fever, exploring its dual role as a protective immune mechanism and a potential physiological risk. It critically examines diagnostic challenges, evidence-based management strategies, and global disparities in fever treatment. Special emphasis is placed on parental perceptions, the overuse of antipyretics, and the emerging role of artificial intelligence in fever diagnosis. Future directions include refining diagnostic biomarkers, implementing digital health tools, and advancing antimicrobial stewardship to curb antibiotic resistance. By improving clinical decision-making and public awareness, this review aims to optimize the management of febrile children worldwide and enhance patient outcomes.
