多种因素相关。进入本试验的病人病情相对较重,研究组APACHE Ⅱ评分(18.5±0.865)分,对照组APACHE Ⅱ评分(17.9±1.429)分,且存在不同程度的营养不良,分解代谢亢进,给予TPN前负氮平衡明显,其中最严重的每日排氮23g,因此要想在短期内纠正负氮平衡不容易。笔者认为本试验检测的时间延长,能观察到研究组较早出现正氮平衡。 【参考文献】 1 Woodcock N,MacFie J.0ptimal nutrition support(and the demise of the enteral versus parenteral controversy).Nutrition,2002,18(6):523-524. 2 Preiser JC,Berre J,Carpentier Y,et al.Management of nutrition in European intensive care units:results of a questionnaire.Working Group on Metabolism and Nutrition of the European Society of Intensive Care Medicine.Intensive Care Med,1999,25(1):95-101. 3 Berger MM,Chiolero RL,Pannatier A,et al.A10year survey of nutritional support in a surgical ICU:1986-1995.Nutrition,1997,13(10):870-877. 4 Jimenez FJ,0rtiz Leyba C,Morales Mendez S,et al.Variations in plasma amino acids in septic patients subjected to parenteral nutrition with a high proportion of branchedchain amino acids.
