Iron supplementation for infants in the NICU: What preparation, how much, and how long is optimal?

Area of Science:

• Neonatal Medicine
• Pediatric Nutrition
• Hematology

Background:

• Preterm infants and those with perinatal risks face elevated iron deficiency and overload risks.
• Inadequate iron in the perinatal period can lead to lasting neurodevelopmental issues.
• Individualized iron supplementation is essential to prevent both deficiency and overload.

Purpose of the Study:

• To review current enteral and parenteral iron formulations for neonates.
• To discuss iron measurement parameters in infants.
• To identify knowledge gaps and areas for future research in neonatal iron supplementation.

Main Methods:

• Literature review of enteral and parenteral iron supplementation in neonates.
• Analysis of iron measurement techniques and their clinical relevance.
• Synthesis of current research findings and identification of ongoing studies.

Main Results:

• Enteral iron supplements are the established standard for neonates.
• Parenteral iron formulations offer an alternative for specific infant populations, including those with intolerance or unresponsiveness to enteral iron.
• Optimal dosing and timing remain subjects of active investigation.

Conclusions:

• Individualized iron supplementation strategies are necessary for at-risk infants.
• Both enteral and parenteral routes have roles, with parenteral options expanding.
• Further research is needed to optimize iron supplementation protocols for improved infant outcomes.
