我国健康人和外科住院患者的静息能量消耗

REE of healthy individuals and surgical patients is China

用开放式间接测热法测定国人静息能量消耗(REE),结果显示:30例健康成人为1227±103kcal/d,比Harris-Benedict公式估算的基础能量消耗(BEE)低9.6％(P<0.05);519例外科门诊住院患者为1187±126kcal/d,比BEE低10.8％(P<0.001);340例择期手术后无并发症患者为1326±133kcal/d,比术前值高10.94％(P<0.001),但与BEE相近(P>0.05);24例外科危重病患者为1641±189kcal/d,明显高于BEE和非应激外科患者的REE(P<0.05和0.01)。作者分析REE和BEE之间差异的可能原因,对Harris-Benedict公式的临床应用作初步评价。

The result of Resting Energy Expenditure(REE)of people in our country, measured with open-circuit indirect calorimery, showded that REE of 30 healthy individuals was 1227±103 kcal/d ,9. 6% lower than the Basal Energy Expenditure (BEE) estimated on Harris-Benedict Equa-tion(P<0. 05). The REE of 519 surgical patients was 1 187±126kcal/d ,10. 8% lower than BEE(P <0. 001). It was 1 326±133 kcal/d of 340 post-operation patients without complication, 10. 94% higher than that of preoperative ones, but only nearer to, and barely enough to meet with BEE(P> 0. 05). Of the 24 critical patient in surgery, it was 1641±189 kcal/d , distinctively higher than BEE (P<0. 05), and REE of non-stree patients (P<0. 01). The authors analysed the possible reasons of the differences between REE and BEE; and evaluated the clinical use of Harris-Benedict Equation.
