Optimizing nutrition of the preterm infant

Area of Science:

• Neonatal nutrition
• Pediatric growth and development

Background:

• Preterm infant nutrition aims to mimic fetal growth and body composition.
• Inadequate nutrition leads to growth failure, increased morbidity, and suboptimal neurodevelopment.
• Growth velocity in the NICU significantly impacts neurodevelopmental and anthropometric outcomes.

Purpose of the Study:

• To present the scientific rationale for nutrient requirements in preterm infants.
• To provide practical guidelines for intravenous and enteral feeding strategies.
• To emphasize the importance of optimizing nutrient intake for growth and neurodevelopment.

Main Methods:

• Review of scientific literature on preterm infant nutrition.
• Analysis of nutrient requirements, including energy, protein, amino acids, carbohydrates, and lipids.
• Discussion of intravenous and enteral feeding approaches.

Main Results:

• Intravenous feeding with amino acids should commence immediately post-birth.
• Early enteral feeding, prioritizing mother's milk, is recommended.
• Trophic enteral feeds should be advanced as tolerated, adjusting IV nutrition concurrently.

Conclusions:

• Optimal nutrition is essential for preterm infant growth, neurodevelopment, and long-term health.
• Established feeding protocols can improve nutritional outcomes.
• Further research is needed to define optimal nutrition for maximal neurocognitive benefits and minimized chronic disease risk.
