Fluid and electrolyte pathophysiology in common febrile illness in children and the implications for clinical...

Area of Science:

• Pediatrics
• Critical Care Medicine
• Pediatric Nephrology

Background:

• Fluid homeostasis and electrolyte balance are critical in managing seriously ill children.
• Global consensus on optimal fluid strategies for pediatric critical care remains challenging.
• Disparities exist in fluid management practices between high-income and low-income countries.

Purpose of the Study:

• To review fluid and electrolyte pathophysiology in common pediatric febrile illnesses.
• To describe the evolution of fluid management strategies in pediatric critical care.
• To provide implications and principles for effective fluid management in critically ill children.

Main Methods:

• This is a narrative review.
• It synthesizes current knowledge on fluid and electrolyte balance in pediatric febrile illnesses.
• It examines the historical development of fluid management guidelines.

Main Results:

• Adverse events from poor fluid management are more readily identified in high-income countries.
• Low-income settings face challenges with fluid availability, adverse event recognition, and healthcare worker training.
• Evolving strategies aim to improve fluid management in critically ill children.

Conclusions:

• Safe fluid management in critically ill children requires tailored strategies, especially in resource-limited settings.
• Understanding fluid and electrolyte pathophysiology is key to developing effective treatment protocols.
• This review supports the WHO Guideline Development Group for Fluid Guidelines in Children.
