【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。更多还原

【Abstract】 Objective:To analyze the value of low dose enteral nutrition(EN)in treatment of septic shock combined with acute gastrointestinal injuryⅢ(AGIⅢ).Methods:Clinical data of septic shock patients combined with AGIⅢadmitted 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 AGIⅢ,low dose EN can improve the intestinal barrier function and systemic inflammatory responses.更多还原
