Parenteral trace elements in children: clinical aspects and dosage recommendations

Area of Science:

• Pediatric Nutrition
• Trace Element Metabolism
• Parenteral Nutrition Therapy

Background:

• Trace element supplementation is crucial in parenteral nutrition (PN) to prevent deficiencies.
• Pediatric trace element requirements for PN have been debated, with recent advancements prompting guideline revisions.
• Short-term PN provision presents specific considerations for trace element dosing.

Purpose of the Study:

• To review current understanding of trace element requirements in pediatric parenteral nutrition.
• To evaluate recent developments influencing trace element supplementation recommendations.
• To address the debate surrounding optimal trace element levels in short-term PN.

Main Methods:

• Literature review of studies on trace element supplementation in parenteral nutrition.
• Analysis of recent clinical findings and expert recommendations.
• Focus on pediatric and neonatal populations, particularly preterm neonates.

Main Results:

• Zinc supplementation is routinely required for parenterally fed preterm neonates.
• Chromium and manganese provision in PN should be limited, especially for short-term patients.
• Newer parenteral iron formulations allow for safer, higher-dose administration.

Conclusions:

• Clinicians must individualize trace element prescriptions for parenteral nutrition.
• Routine use of "all-in-one" parenteral trace element preparations is discouraged in pediatrics.
• Tailored PN trace element provision minimizes toxicity risk and optimizes patient outcomes.
