Hypophosphatemia in critically ill children

Area of Science:

• Pediatric Intensive Care Medicine
• Clinical Nutrition
• Critical Care Nephrology

Background:

• Hypophosphatemia is a significant electrolyte disturbance in critically ill patients.
• Understanding its prevalence and risk factors in pediatric intensive care units (PICU) is essential for patient management.
• Previous reviews have not specifically focused on the pediatric population in PICU settings.

Purpose of the Study:

• To review clinical studies on hypophosphatemia in pediatric intensive care unit patients.
• To determine the prevalence of hypophosphatemia in this population.
• To identify associated risk factors for hypophosphatemia in critically ill children.

Main Methods:

• Systematic literature search of Medline, Embase, Cochrane Library, and LILACS databases.
• Inclusion criteria focused on clinical trials and studies published between January 1990 and January 2004.
• Exclusion criteria included specific conditions like prematurity, genetic syndromes, and renal diseases.

Main Results:

• The prevalence of hypophosphatemia in critically ill pediatric patients exceeded 50%.
• Commonly associated factors included refeeding syndrome, malnutrition, sepsis, trauma, and diuretic/steroid therapy.
• Limited high-quality studies (one clinical trial, one retrospective study) were identified, with most being case reports.

Conclusions:

• Hypophosphatemia is highly prevalent in critically ill children.
• Refeeding syndrome, malnutrition, sepsis, trauma, and certain therapies are key associated risk factors.
• Early detection and management of hypophosphatemia are crucial to prevent complications in pediatric intensive care settings.
