Effectiveness of pulmonary rehabilitation and correlations in between functional parameters, extent of thoracic surgery and severity of post-operative complications: randomized clinical trial.

Background: Pulmonary rehabilitation can be effective in perioperative condition. Our aim was to examine whether the changes of functional markers are significant and search connections between these values and the severity of postoperative complications.

Methods: A total of 238 chronic obstructive pulmonary disease (COPD) patients underwent perioperative pulmonary rehabilitation with thoracic surgery.
