Respiratory Variability and Postoperative Complications During Thoracic Lung Resection.

Postoperative respiratory complications (PRC) represent a major public health issue. Majority of PRCs occur once the patient leaves the post-interventional monitoring room. Identifying patients at risk for PRC is therefore an important step for improving their post-operative care. In this context, any clinical marker making it possible to detect early alteration of the respiratory state in the postoperative phase deserves to be evaluated. This study is based on the hypothesis that measuring indices of respiratory variability which is synonymous with "good respiratory health" can be part of these markers. The measurement of respiratory variability will be done in patients with thoracic lung resection surgery before anesthetic induction and in the postoperative phase after extubation. It will be measured using a belt equipped with an external sensor allowing automatic and continuous analysis of thoracic movement by frequency analysis
