Preoperative management using inhalation therapy for pulmonary complications in lung cancer patients with chronic obstructive pulmonary disease

Abstract

ObjectiveThis study aimed to investigate whether perioperative inhalations of long-acting beta-agonists (LABAs) or long-acting muscarinic antagonists (LAMAs) might decrease the incidence of postoperative complications in lung cancer patients with chronic obstructive pulmonary disease (COPD).MethodsWe retrospectively analyzed 108 patients with COPD who underwent pulmonary resections for primary lung cancer at our hospital between January 2013 and January 2016 to determine the association between the incidence of postoperative complications (e.g., prolonged air leakage and pneumonia) and the use of LABAs or LAMAs.ResultsThirty patients with COPD experienced postoperative complications (27.8%): Fourteen patients had prolonged air leakages (more than 7 days), ten patients developed pneumonia. The frequency of these postoperative pulmonary complications was significantly higher among the patients with COPD (24/108 cases, 22.2%), compared with the frequency among non-COPD patients (15/224 cases, 6.7%). Inhaled bronchodilators, such as LAMA or LABA, were prescribed for 34 of the 108 patients with COPD; the remaining 74 patients were not treated with bronchodilators. Pulmonary complications were significant lower among the LAMA or LABA users (3/34 cases, 8.8%) than among the untreated COPD patients (21/74 cases, 28.4%).ConclusionFor lung cancer patients with COPD, preoperative management using LABA or LAMA bronchodilators and smoking cessation can reduce the frequency of postoperative pulmonary complications after surgical lung resection. LAMA or LABA inhalation might be useful for not only perioperative care, but also for the long-term survival of COPD patients after surgery.
