Transition phase of nutrition-optimizing nutrient administration

Area of Science:

• Neonatology
• Pediatric Nutrition
• Clinical Practice

Background:

• Preterm infants, especially very low birth weight (VLBW) infants, require specialized nutritional support.
• Transitioning from parenteral nutrition (PN) to enteral feeding (EN) is critical for growth and neurodevelopment.
• This transition phase presents significant clinical challenges and variability.

Purpose of the Study:

• To explore complex nutritional management during the PN to EN transition in preterm infants.
• To provide practical recommendations for optimizing nutrient delivery and growth.
• To reduce the risk of postnatal growth failure in VLBW infants.

Main Methods:

• Discussion of clinical challenges in PN to EN transition.
• Review of key decision points: initiating EN, increasing volumes, fortification, and discontinuing PN components (ILE, amino acids).
• Synthesis of evidence-informed recommendations for management.

Main Results:

• Identified key challenges: timing of EN initiation, rate of advancement, fortification timing, and PN cessation criteria.
• Proposed practical recommendations: early human milk fortification, concentrated PN, and minimizing transition duration.
• Emphasized the importance of strategic management for optimal outcomes.

Conclusions:

• Effective management of the PN to EN transition is crucial for preterm infant growth and development.
• Early fortification and strategic PN use can optimize nutrient delivery.
• Minimizing transition duration is key to preventing growth failure in VLBW infants.
