ABSTRACT
Objective To investigate the influence of bifidobacterium on inflammatory response of brain traumatic injury patients.Methods According to the sequence of patients'admission time,a total of 60 patients with traumatic brain injury were randomly divided into the research group and the control group,30 cases in each group.The research group was fed intestinal nutrient solution combined with bifidobacterium,and 1 × 108cfu/d bacteria every day.The control group was skimpily given enteral nutrient solution.The WBC counts,C-reactive protein (CRP) and interleukin-6 (IL-6),GCS score and infection status,ICU length of stay and 30 days mortality in the 1 st,5th,10th,15th day of enteral nutrition were recorded by health care professionals.Results The leukocyte count,CRP and inflammatory factors IL-6 of the research group were significantly lower than those in the control group in the 15th day of enteral nutrition[(8.02 ± 2.47) × 109/L vs (10.54 ± 3.98) × 109/L,(28.02 ± 9.43) mg/L vs (70.54 ± 13.92) mg/L,(61.02 ± 22.43) ng/L vs (83.52 ± 14.94) ng/L; t =5.474,6.231,9.343,P =0.029,0.049,0.001] ;The GCS score of the two groups gradually increased,and which of the first 10 days had no significant differ ence between the two groups.In the 15th day of enteral nutrition,GCS score of the research group was significantly higher than the control group [(12.02 ± 2.12) point vs (10.12 ± 4.94) point,t =9.744,P =0.000].The incidence rate of infection of research group was significantly lower than that of the control group,but ICU length of stay shortened (16/30 vs 27/30,x2 =9.610,P =0.002).No significant difference was observed in 30-day mortality between the two groups.Conclusion Adding an appropriate amount of probiotics in enteral nutrition on regular basis can significantly reduce the body's inflammatory response and the incidence of infection in patients,shorten hospitalization days.
