摘要：目的总结外科危重病人应用肠外营养与肠内营养支持的方法及经验。方法本组病例应用肠内营养(EN)支持26例，全部通过鼻肠管滴入安素或爱伦多溶液；通过中心静脉肠外营养(CV-TPN)50例，周围静脉肠外营养(PV-TPN)52例，均应用3升营养袋匀速滴人全合一营养液(TNA)。结果26例全胃切除术后病人应用肠内营养，无一例死亡及其他严重并发症。应用TPN组有3例死亡，死亡原因与TPN无直接关系。病人恢复快，平均住院天数缩短。结论由于外科危重病人存在独特的代谢特点，大部分病人存在营养不良，故营养支持对外科危重病人至关重要，直接影响病人的康复和预后。因此对外科危重病人应该进行积极的营养支持治疗。
