    Abstract:
    OBJECTIVE: To evaluate the effects of perioperative enteral immunonutrition on the nutritional status, immunity, and inflammatory response of the elderly patients. METHODS: Eighty malnourished patients aged over 60 with malignant gastrointestinal tumors undergoing radical surgery were randomly divided into 2 groups: experimental group (immunonutrition group, n = 37), and control group (n = 43). In the experimental group Supportan and glutamine, with the calorific value of 125.4 kJ.kg(-1).d(-1), were given orally or by nasointestinal tube for 5 days before operation, through jejunostomy or nasointestinal tube during operation, and then through nasointestinal tube since the day 2 to day 9 after post-operationally. In the control group Nutrition with the same amount of calorific value was given in the same manner as mentioned above. Peripheral blood samples were collected 5 and 1 days pre-operationally, and 1 and 9 days post-operatively to examine the serum albumin (ALB), prealbumin (PA), transferrin (TFN), CD3, CD4, CD8, CD4/CD8, immunoglobulin (Ig) G, IgA, IgM, and C-reactive protein (CRP). RESULTS: Nine days after operation, the serum TFN was 2.18 g/L +/- 0.29 g/L, PA was 0.23 g/L +/- 0.09 g/L, CD4 was 33.8% +/- 5.4%, CD4/CD8 was 1.17 +/- 0.12, and IgG was 13.2 g/L +/- 1.8 g/L. all significantly higher than those of the control group (1.95 g/L +/- 0.28 g/L, 0.19 g/L +/- 0.03 g/L, 31.1% +/- 5.2%, 1.05 +/- 0.10, and 12.11 g/L +/- 1.53 g/L respectively, all P < 0.05). CONCLUSION: Perioperative enteral immunonutrition improves the nutritional status and immune function, und reduces the acute inflammatory response of elderly patients.
