Clinical Trial Summary

After conventional cardiac surgery, many respiratory complications are possible. Therefore, the resuscitator prescribe physiotherapy and non invasive ventilation. The physiotherapist has few reliable tools to evaluate and follow the patient on his ventilatory function. Currently, lung ultrasound is little used in physiotherapy and no study explains the link between the lung ultrasound results and oxygenation patient state. Before considering the interest of lung ultrasound score as a criterion of effectiveness of a physiotherapy treatment through future studies, it is first important to objectivize the existence of a relationship between lung ultrasound score and the PaO2/FiO2 ratio after cardiac surgery. Lung ultrasound could provide direct clinical information without having to resort to other more invasive examinations to objectify the improvement of the patient's oxygenation. Main objective To show that the relative change in the PaO2/FiO2 ratio correlates with the change in lung ultrasound score measured in the short term between the beginning and the end of the first physiotherapy session associated with non invasive ventilation the day after surgery in cardiac patients Secondary objectives - To study the inter-operator (2 readers) reproducibility of the lung ultrasound score measurement. - To study the relationship between the relative variation of the PaO2/FiO2 ratio and the variation of each of the 12 zones of the lung ultrasound score - To Study the relationship between the initial lung ultrasound score and the relative variation of the PaO2/FiO2 ratio - To study the relative variation of the PaCO2 and the variation of the lung ultrasound score between the beginning and the end of the first session of physiotherapy management associated with NIV - To obtain from the patient in the short term feedback on his or her understanding of the explanations about lung ultrasound score provided by the physiotherapist during the session

Outcome

Type Measure Description Time frame Safety issue
Primary Relative difference in PaO2/FiO2 ratio: (measurement after - measurement before the physiotherapy session + non invasive ventilation) / measurement before.) The higher the ratio, better is the result. Between approximately 0 and 400 the morning after the heart surgery
Primary Difference in lung ultrasound score: measurement after - measurement before the physiotherapy session + non invasive ventilation Lung ultrasound score = global measurement on 12 thoracic regions (6 per hemithorax: 2 anteriors, 2 laterals, 2 posteriors) to obtain a result out of 36 (sum of all values found in each zone). Each zone is evaluated as follows:
0 = normal ventilation
= multiple B-lines defined
= coalescing B-lines
= pulmonary consolidation
the morning after the heart surgery
Secondary Lung ultrasound score values obtained by both evaluators from the same recorded ultrasound images. If there is a difference of one point between the two scores measured, a third reading by a doctor will be taken. This 3rd score will then be retained. If there is a difference of one point between the two scores measured, a third reading by a doctor will be taken. This 3rd score will then be retained. in the week following the measurements
Secondary relative difference in PaO2/FiO2 ratio The higher the ratio, better is the result. Between approximately 0 and 400 the morning after the heart surgery
Secondary difference in lung ultrasound score for each study area Each zone is rated from 0 to 3 points. The lower the score, the better the result. We look to see if the score for each zone decreases between before and after the physiotherapy session. the morning after the heart surgery
Secondary initial lung ultrasound score Lung ultrasound score = global measurement on 12 thoracic regions (6 per hemithorax: 2 anteriors, 2 laterals, 2 posteriors) to obtain a result out of 36 (sum of all values found in each zone). Each zone is evaluated as follows:
0 = normal ventilation
= multiple B-lines defined
= coalescing B-lines
= pulmonary consolidation
the morning after the heart surgery
Secondary relative difference in PaCO2 The lower the score, the better the result. Ap proximately between 0 and 100 the morning after the heart surgery and after physiotherapy session
Secondary For each subject, answers to two questions at the end of the session about his or her understanding of PAS after the information provided by the MK during the session Questions asked by the physiotherapist for the patient (at the end of the session) :
Did you understand the explanations provided by the physiotherapist regarding the lung ultrasound results? Yes, completely Yes, partially No No answer
Did the explanations provided by the physiotherapist regarding the results of the lung ultrasound score help you understand the movements or displacements that the physiotherapist asked you to make during this session? Yes, completely Yes, partially No No answer
