Abstract:Objective To study the efficacy of probiotics combined with enteral nutrition with a nonelemental diet in the treatment of sepsis and its effects on intestinal function, inflammatory factors and immune function. ?Methods?A total of 134 patients with sepsis admitted to our hospital from June 2015 to June 2018 were divided into the observation group (n = 67) and the control group (n = 67) randomly. Both groups were given basic treatment including anti-infection, fluid resuscitation, debridement and drainage, and mechanical ventilation, based on which the observation group was additionally treated with Bifidobacterium quadruple viable tablets combined with enteral nutrition with a nonelemental diet. APACHE-II and SOFA scores, intestinal function, inflammatory factor level and peripheral blood T lymphocyte subsets were observed before treatment, 3 days and 10 days after treatment. The conditions of cure, death or survival outcome in the two groups were followed up for 3 months after discharge.?Results?The cure rate of the observation group [89.55% (60/67)] was higher than that of the control group [79.10% (53/67)], and the mortality rate of the observation group [5.97% (4/67)] was lower than that of the control group [11.94% (8/67)] (P < 0.05). The APACHE-II and SOFA scores of the both group were different at distinct time points (P < 0.05), and were significantly different between the observation group and the control group (P < 0.05). There was a difference in the change trend of APACHE-II and SOFA scores between the observation group and the control group (P < 0.05). There was no statistically significant difference in the intestinal function score before treatment between the observation group and the control group (P > 0.05), while the intestinal function score after treatment of the observation group was higher than that of the control group (P < 0.05). The levels of PCT, IL-6, CRP, and SAA were different at different time points (P < 0.05), and were different between the observation group and control group (P < 0.05). There were differences in the change trends of PCT, IL-6, CRP and SAA levels between the observation group and the control group (P < 0.05). Besides, the levels of CD3+, CD4+ and CD4+ / CD8+ were different at different time points (P < 0.05) and were different between the two groups (P < 0.05). There was a difference in the change trend of CD3+, CD4+ and CD4+ / CD8+ levels between the observation group and the control group (P < 0.05).?Conclusions?Probiotics combined with enteral nutrition with a nonelemental diet can improve the curative effect for sepsis, enhance the intestinal function, positively regulate the inflammatory factors and immunity, and reduce mortality effectively.
