摘　　要：为给外科危重病人提供合理的营养支持治疗，作者观察了计算机控制的间接能量代谢测量仪对１５例重危病人和２０例单纯营养不良病人全肠外营养支持的指导作用。结果：应激病人的实测能量消耗比ＨＢ公式预测值明显高，平均高１８０１５８０Ｊ／ｄ，按ＨＢ公式加临床各种校正因素预测的能量消耗值比实测能量消耗高２０１８９４０Ｊ／ｄ。表明通过能量代谢监测，可以决定营养物质的供给总量和供给比例，还能根据监测结果随时对营养支持方案进行调整，达到合理营养支持的目的。ndirect calorimetric measurements were niade witha MedGraphics Critical Care Monitor (CCM) desktopanalysis system in the observation of critically ill andnialnourished patient's energy expenditure. In 15 criti-cally ill patients , predicted energy requirements based on1. 75 times BEE calculated by HarrisBenedict formulaor corrected Harris-Benedict formula averaged 32. 7%and 27. 8% greater than metabolic expenditure mea-sured by indirect calorimetry respectively. In the 20 un-stressed malnourished patients, predicted energy re-quirements based on the HarrisBenedict (BEE) formulaaveraged 15% to 20% higher than metabolic expendi-ture measured by indirect calorimetry. When the criti-cally ill patients' total energy intakes were 1. 2 timesresting energy expenditure, their nutritional state couldbe maintained in normal conditions. While the malnourished patients were provided with 1. 5 × REE in energyintake. the malnourished state could be reversed. Webelieved that the critically ill and malnourished patients’energy expenditures are better measured than predictedand their nutritional regimens should be guided underthe computerized indirect calorimetry.
