RESUMO
Objective:To analyze the value of low dose enteral nutrition (EN) in treatment of septic shock combined with acute gastrointestinal injury Ⅲ (AGI Ⅲ).Methods:Clinical data of septic 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 Ⅲ,low dose EN can improve the intestinal barrier function and systemic inflammatory responses.
