[摘要]目的 评价肠内营养(EN)对胃癌根治术后禁食病人血浆内毒素水平的影响。方法 70例因胃癌行全胃切除术病人随机分为EN组和肠外营养(PN)组，各35例，分别给予管饲EN和外周PN支持，测定治疗前、治疗后第1、3、7天血浆中的内毒素水平变化。结果 术前和术后第1天，EN和PN组内毒素水平无显著性差异( t=0.539，P >0.05)，术后第3、7天两组血浆内毒素水平较术前增高，差异有显著性( F=18.910、26.528， P < 0.001);术后第3、7天，EN组内毒素水平低于PN组，差异有显著性( t=2.013、2.867，P <0.05、 0.01 )。结论 相对于PN而言，EN可减少胃癌根治术后禁食病人的内毒素移位。
