Optimal nutrition in the paediatric ICU

Area of Science:

• Pediatric intensive care
• Clinical nutrition
• Critical illness

Background:

• Undernutrition increases morbidity and mortality in critically ill children.
• Obesity is linked to complications and poorer outcomes in specific pediatric populations, like burn injuries.
• The relationship between nutritional status and organ function (beyond skin healing) is understudied.

Purpose of the Study:

• To review the best available evidence on optimal nutrition in pediatric intensive care.
• To examine nutritional strategies based on surrogate and hard clinical outcome parameters.
• To identify gaps in current knowledge regarding pediatric critical care nutrition.

Main Methods:

• Literature review of current evidence on pediatric intensive care nutrition.
• Analysis of studies linking nutritional status to clinical outcomes.
• Assessment of data on enteral nutrition delivery and protein intake.

Main Results:

• Evidence suggests a link between adequate enteral nutrition and protein delivery with improved hospital stay, neurological status, and mortality.
• Data on long-term follow-up and health economics related to pediatric critical care nutrition are scarce.
• Current nutritional strategies rely on limited trials with surrogate outcomes, lacking causal evidence.

Conclusions:

• No randomized controlled trials have established causal links between feeding regimens and outcomes in critically ill children.
• Optimal nutritional strategies are currently based on limited evidence and surrogate markers.
• Prospective randomized studies are essential to determine optimal feeding strategies for critically ill children.
