Measurement of Resting Energy Expenditure via Indirect Calorimetry Among Adult Hemodialysis Patients
Abstract Objective: To determine if the hemodialysis procedure results in increased resting energy expenditure (REE) and to compare the estimation equations for determining energy requirements with measured REE. Design: Repeated measures design and correlational analysis. Setting: Free-standing outpatient hemodialysis facility. Patients: Eight medically stable hemodialysis patients. Intervention: REE measured via indirect calorimetry at baseline and 30-minute intervals during hemodialysis. Time control REE measured on nondialysis day. Main outcome measure: REE. Results: No difference was found between dialysis REE and control. There was no change in REE over the course of hemodialysis procedure. Measured REE was significantly lower than Harris Benedict basal energy expenditure. Low correlation was found between estimation equations and measured REE. Conclusion: The hemodialysis procedure does not result in increased energy demands.
