What method is recommended to calculate energy prescriptions in critically ill and postoperative neonates?

• A. Indirect calorimetry
• B. Basal energy expenditure estimate of 55-60 kcal/kg/day
• C. Standard 100 kcal/kg/day
• D. Predictive equations with activity factor only

Answer: (A)

Direct measurement of energy expenditure through indirect calorimetry is the preferred approach because critically ill and postoperative neonates have highly variable metabolic needs driven by stress, infection, and tissue healing. Indirect calorimetry estimates energy use by measuring oxygen consumption and carbon dioxide production, giving a current, patient-specific energy target. Fixed values or basal estimates don’t account for the dynamic changes in these tiny patients and can lead to underfeeding or overfeeding with negative consequences for growth and recovery. When available, this method provides the most accurate energy prescriptions to support optimal outcomes.
