Use of tiotropium bromide for pre-operative treatment in chronic obstructive pulmonary disease patients: comparison with oxitropium bromide.

摘要

OBJECTIVE: Chronic obstructive pulmonary disease (COPD), which ranks fifth in terms of the global burden of diseases, is one of the major risk factors of post-operative pulmonary complications. Tiotropium bromide is a new inhaled bronchodilator for COPD patients with a sustained duration of action; it has superior efficacy compared to other bronchodilators. However, little is known regarding its clinical value as a preoperative treatment for COPD patients. In this study, we compared the incidence of post-operative complications between COPD patients who received with tiotropium bromide and those who did not. METHODS: Retrospective study. PATIENTS: For 1 month before surgery we examined 84 and 82 patients treated with tiotropium bromide (tiotropium group) and oxitropium bromide (oxitropium group), respectively, in combination with other medications. We performed a statistical comparison of clinical features, pulmonary functions, and postoperative complications between the 2 groups. RESULTS: The improvements in clinical symptoms and forced expiratory volume in 1 second were better in the tiotropium group than in the oxitropium group. The incidence of post-operative pulmonary complications (refractory bronchospasm, pulmonary infection, and acute respiratory failure) was significantly lower in the tiotropium group than in the oxitropium group. Three patients in the tiotropium group complained of dry mouth; however, the symptoms could be controlled. The incidence of post-operative non-pulmonary complications was not significantly different between the 2 groups. CONCLUSION: We propose that tiotropium bromide might be a safe and useful drug for pre-operative treatment of COPD patients.
