摘　　要：目的:观察小剂量肠内营养(EN)在脓毒性休克伴急性胃肠道损伤(AGI)病人治疗中的价值。方法:将在我院ICU接受治疗的84例脓毒性休克伴AGIⅢ级病人,依据是否采用EN治疗分为观察组(EN治疗,n=41)和对照组(无EN治疗,n=46)。对比两组病人的病死率、入住ICU时间,检测两组病人治疗前和治疗后1周肠屏障功能、系统性炎症和应激指标。结果:观察组病人EN剂量为836.8~1 715.4 k J(200~410 kcal)/d,中位剂量为1 464.4 k J(350 kcal)/d,未出现严重的EN并发症。两组病人病死率比较无显著性差异(24.4%vs 32.6%,P=0.398),但观察组病人入住ICU时间显著短于对照组,(11.8±3.7 vs 16.2±5.3,P<0.01);治疗后1周后,外周血C反应蛋白(CRP)、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、外周血二胺氧化酶(DAO)、内毒素(ET)和D-乳酸水平均显著低于对照组(P<0.05)。结论:对合并AGI的脓毒性休克病人,即便给予小剂量EN仍具有改善病人肠屏障功能和系统性炎性反应的作用。Objective： To analyze the value of low dose enteral nutrition （EN） in treatment of septic shock combined with acute gastrointestinal injury m （ AGI m ）. Methods： Clinical data of sep- tic shock patients combined with AGI Ⅲ admitted at our hospital were analyzed. Patients were divided into two groups according to the nutrition therapy they received： treatment group （EN, n =41 ） and control group （no EN, n = 46）. The mortality and ICU hospital stays were collected. The intestinal barrier, inflammatory cytokines, and oxidative stress were evaluated before and after EN treatment. Results： For patients in the treatment group, the dosages of EN ranged from 200 to 410 kcal/d, with the median dose of 350 kcal/d. No significant differences were found on death rates between the two groups （24.4% vs 32.6%, P = 0. 398 ）. Patients in the treatment group had shorter ICU hospital stays than those of the control group （11.8±3.7 vs 16.2 ±5.3, P 〈0.01 ）. After one week EN treatment, patients in the treatment group had lower levels of CRP, IL-6, TNF-α, diamine oxidase, endotoxin and D-lactate than those of the control group （P 〈 0. 05 ）. Conclusion ： For septic shock patients combined with AGI m, low dose EN can improve the intestinal barrier function and systemic inflammatory responses.
