【摘要】 目的 探讨临床使用的全肠外营养液(TPN)实际能量与理论上所需的标准能量的相符性，以及其主要能量组分所占比例的合理性。方法 随机抽取了2006年1月～6月份住院病人使用的200张TPN医嘱,运用HBE(Harris Benedict Equation)标准能量公式计算住院病人所需的理论标准能量。结果 理论标准能量与实际提供的能量进行比较，经数理统计中的T分布方法进行处理，表明两者的差异有显著性(P<0.2)。结论 邵逸夫医院TPN所提供的总热卡总体低于理论标准能量,其主要能源的分布基本合理。

    【Abstract】 Objectives To discuss the correspondence between the actual energy which supplied by TPN of hospital and the standardized energy which needed in theory,and the rationality of the proportion which the main energy sources hold.Mothed Elective 200 shares TPN by doctor’s advices from Jan.2006 to June 2006 which the inpatients used.Manage the HBE(Harris Benedict Equation) standardized energy formulate,work out the standardized energy in theory.Results Compare the standardized energy in theory to the actual energy supplied ,by the T distributing mothed of mathematical statistics,find there were significantly different(P<0.2). Conclusions The actual energy supplyed by the TPN of hospital is lower than the standared energy,the distribution of the energy sources is reasonable. ......
