Abstract: Infants undergoing surgery have unique metabolic demands. The stress of an operation and recovery combined with expectations for growth and development imply elevations in energy expenditure beyond that of healthy, free-living infants. In contrast, surgery may trigger a diversion of energy utilization from tissue accumulation and growth toward the catabolic stress response and cytokine production. Predictive equations are commonly used in clinical settings to estimate basal or resting energy expenditure because measurement techniques such as indirect calorimetry may not be feasible or available. Investigations of measured energy expenditure in surgical infants have portrayed mixed results, however, and estimation equations may not consistently lead to accurate assessment of actual energy needs. Studies are limited in number and quality and often involve a heterogeneous, small population. Grouped outcomes may conceal the wide variability frequently observed in these studies. Measurement of energy expenditure is therefore preferable to the use of predictive equations to customize nutrition intervention for individual infants undergoing surgery.
