摘要：

PURPOSE: The aim of this investigation was to compare the resting energy expenditure (REE) calculated by the Harris-Benedict equation (REEHB) with the REE measured by indirect calorimetry (REEIC) in critically ill surgical patients under mechanical ventilation. METHODS: Thirty patients were included in this work. REE was calculated by the Harris-Benedict equation (REEHB) using real body weight, and it was also measured by indirect calorimetry (REEIC), which was performed for 30 minutes. RESULTS: REEHB had significant (p < 0.0005) but low correlation (Spearman r = 0.57) with REEIC, with a mean bias of 12 kcal.d(-1) and limits of agreement ranging from - 599.7 to 623.7 kcal.d(-1) as detected by the Bland-Altman analysis. CONCLUSION: These findings suggest that REEIC seems to be more appropriate than REEHB for accurate measurement of REE in critically ill surgical patients under mechanical ventilation.
