Objective:to evaluate clinical curative effects of low carborhydrate and high fat enteral nutrition in chronic obstructive pulmonary disease(COPD) patients complicated by respiratory failure.Methods:60 patients with COPD patients complicated by respiratory failure were randomly divided into two groups(people in the treatment group and the control group are all 30).Anti-infection

oxyen inhalation

spasmolysis and anti-asthma

eliminating phlegm

correcting acid-base inbalance and electrolyte disorder and so on were used in both groups.The treatment group were given low carborhydrate and high fat enteral nutrition support

while the control group were given traditional nutritional support for 10 days.When one day before and 10 days after the study

blood gas analysis index

respiratory function condition were determined in the two groups of patients.Results:The levels of blood gas analysis index

respiratory function condition in the treatment group were increased significantly as compared with the control group(P<0.05).Conclusion:Low carborhydrate and high fat enteral nutrition support can evidently improve the signs and symptoms of the COPD patients concurrent respiratory failure.Can also obviously improve human blood gas analysis and lung function.It has a good curative effect in correcting respiratory failure.
