  • Title: Predicting energy expenditures in burned patients.
    Author: Turner WW, Ireton CS, Hunt JL, Baxter CR.
    Journal: J Trauma; 1985 Jan; 25(1):11-6. PubMed ID: 3965733.
    Abstract:
    Daily caloric requirements in patients with major burns are frequently estimated using the Curreri formula (25 X body weight (kg) + 40 X % BSA burned). In nonburned patients modifications of the Harris-Benedict formulas have been used to estimate energy requirements. These equations have not been validated against measured energy expenditures in burned patients. Thirty-five patients with second- and third-degree burns covering from 10 to 75% of the body surface area underwent assessments of energy expenditures by indirect calorimetry and by the Curreri and Harris-Benedict formulas. The mean energy expenditure calculated from the Harris-Benedict formulas (BEE) underestimated the mean measured energy expenditure (MEE) by 23% (p less than 0.001), while the mean energy expenditure calculated from the Curreri formula (CEE) overestimated the mean MEE by 58% (p less than 0.001). There were significant correlations between the MEE, BEE, and CEE. In patients with burns greater than 20% of the body surface area, the correlation between MEE and BEE was higher than that found with the Curreri formula.
