Effect of adjuvant tiotropium bromide therapy on the oxygenation function and inflammatory response in patients with COPD and type Ⅱ respiratory failure

摘要

Objective:To explore the effect of adjuvant tiotropium bromide therapy on the oxygenation function and inflammatory response in patients with COPD and type Ⅱ respiratory failure. Methods:a total of 58 patients with COPD and type II respiratory failure treated in our hospital between August 2012 and January 2016 were collected and divided into observation group (n=29) and control group (n=29) according to the single blind randomized control method. Control group of patients received clinical routine treatment, and observation group of patients received adjuvant tiotropium bromide treatment on the basis of routine treatment. Before treatment and 30d after treatment, spirometer was used to determine pulmonary ventilation function;blood gas analyzer was used to test oxygenation function indexes;enzyme-linked immunosorbent assay (ELISA) was used to detect serum inflammatory factor levels.Results: Before treatment, differences in pulmonary ventilation function, oxygenation function and serum inflammatory factor levels were not statistically significant between two groups of patients. 30 d after treatment, FEV1, FEF75%, PEF, PaO2/FiO2, DO2 and O2ER levels of observation group were significantly higher than those of control group while VO2 level was significantly lower than that of control group;serum IL-1β, IL-18, IL-27 and CRP levels were significantly lower than those of control group.Conclusion:Adjuvant tiotropium bromide treatment can optimize the pulmonary ventilation and oxygenation function and reduce systemic inflammatory response in patients with COPD and type II respiratory failure.
