Perioperative short-term pulmonary rehabilitation for patients undergoing lung volume reduction surgery

Although pulmonary rehabilitation is recommended for patients undergoing lung volume reduction surgery, the optimal method of pulmonary rehabilitation is unclear. The aim of this study was to determine the feasibility and safety of perioperative short-term pulmonary rehabilitation. We enrolled candidates for lung volume reduction surgery from 1999 to 2006 and retrospectively evaluated the feasibility and safety of perioperative short-term pulmonary rehabilitation for these patients. The program included the progressive exercise training on a treadmill for approximately 3 weeks. Two primary endpoints, feasibility and safety, were determined by the adherence rates of the program session and the adverse events. Pulmonary function and exercise capacity were evaluated at baseline and the termination of pre- and postoperative short-term pulmonary rehabilitation. Twenty-two patients were enrolled in this study. All patients completed our program without any serious adverse events. The mean values of adherence rates of the preoperative, postoperative, and overall period were, 89.1%, 95.1%, and 92.1%, respectively. All values of pulmonary function tests, except for forced vital capacity, significantly improved at the termination of postoperative short-term pulmonary rehabilitation in comparison to those at the termination of preoperative short-term pulmonary rehabilitation. The values of the 6-minute walk distance, total exercise time, and maximal workload on incremental exercise test were significantly improved by preoperative short-term pulmonary rehabilitation, and their values were maintained until the termination of postoperative short-term pulmonary rehabilitation. The results indicated that it is both feasible and safe to perform perioperative short-term pulmonary rehabilitation.
