Nutrition in Pediatric Intensive Care: A Narrative Review

Area of Science:

• Pediatric critical care medicine
• Clinical nutrition
• Metabolic support

Background:

• Critically ill children have higher metabolic demands and lower energy reserves than adults, increasing starvation vulnerability.
• Prompt initiation of nutrition support post-admission and stabilization is vital.
• Enteral nutrition is preferred over parenteral when feasible.

Purpose of the Study:

• To outline optimal nutrition support strategies for critically ill children.
• To emphasize the importance of early and appropriate nutritional interventions.

Main Methods:

• Review of current evidence and clinical guidelines for pediatric intensive care nutrition.
• Discussion of enteral nutrition routes and timing.
• Emphasis on macronutrient requirements during different illness phases.

Main Results:

• Early enteral nutrition (oral or gastric tube) is recommended if no contraindications exist.
• High protein delivery is crucial during the acute catabolic phase.
• Adequate energy provision is essential for the subsequent anabolic and rehabilitation phases.

Conclusions:

• Nutrition support is a cornerstone of pediatric intensive care.
• Tailoring nutrition strategies to the child's metabolic state and illness phase optimizes outcomes.
• Timely and appropriate nutrition management facilitates recovery and improves prognosis.
