RESPIVARIA: Respiratory Variability and Postoperative Complications During Thoracic Lung Resection.
Study Details
Study Description
Brief Summary
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

Detailed Description
Postoperative respiratory complications (PRC) represent a major public health issue. By PRC, we mean acute respiratory distress, bronchospasm, pleural effusion, respiratory infection, atelectasis, aspiration pneumonia and pneumothorax.
Postoperative respiratory dysfunction reaches its peak in the 48 hours following surgery. Majority of PRCs therefore occur once the patient leaves the post-interventional monitoring room.
Identifying patients at risk for PRC is an important step for improving their post-operative care. For this, there are predictive scores, notably the ARISCAT score, pre-operatively. However, there are few measurement methods to detect early alteration of the respiratory state in the postoperative phase. Therefore, the physician in charge of the patient is alerted late if the patient deteriorates on the respiratory plan.
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. Therefore, this study is based on the hypothesis that measuring indices of respiratory variability can be part of these markers. Consequently, this research which aims to describe these indices of respiratory variability is of major interest.
Respiratory variability is synonymous with "good respiratory health". By the opposite, the reduction of this same variability is pathological and indicates an increase in the level of load imposed on the respiratory system.
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

Outcome Measures
Primary Outcome Measures
- Coefficient of variation [Day 1]
Each respiratory cycle is defined by an inspiratory time followed by an expiratory time. Ordinary, it is observed a variability compared to the previous cycle in terms of amplitude and temporality. Coefficient of variation is one of the parameters able to measure this respiratory variability.
