ObjectiveTo investigate the clinical effects of active nutritional support on clinical outcome in aged patients with COPD.Methods128 aged patients with COPD were randomly divided into two groups: the control group(64 cases) and the observation group(64 cases), the two groups accepted the same anti-infection, antispasmodic asthma, cough and phlegm, and oxygen treatment．In addition, the observation group were given active nutritional support, such as amino acids, fat emulsion, albumin, and glucose, while the control group were giren normal diet. The total rate of clinical effective, The average hospitalization days, lung function, nutritional status, serum uric acid, the rate of mortality and complications were observed of the two groups during hospitalization.ResultsCompared with the control group,the total effective rate was higher and the average length of stay was less in the intervention group (P＜0.05);nutritional status, lung function, serum urine acid in the intervention group were superior to the control group (P＜0.05）. ConclusionOn the basis of routine treatment, active nutritional support for aged patients with COPD could raise the therapeutic effect, improve nutritional status and lung function，shorten the time of hospitalization.
