Respiratory Weaning Following Cardiac Surgery.

University Hospital, Toulouse

Overview

Respiratory weaning failure worsens prognostic of patients following on-pump cardiac surgery. There are increasing evidences that pulmonary, diaphragmatic or cardiologic echographies are useful in order to improve this critical medical status. Based both on a previous study conducted in the critical care unit of Purpan and on literature we hypothesize that a combined thoracic echography score could be of interest. We make the hypothesis that the use of a score based on thoracic combined echography (ETC = cardiac, pulmonary and diaphragmatic) allows to predict the failure of respiratory weaning in cardiac surgery and allows to improve the characterization of the causes of this failure

Outcomes

Primary Outcomes

Evaluation of predictive value of combined Thoracic Echography (ETC) as assessed by difference in the ETC score before and after extubation

Time frame: 1 hour after the weaning test and 48h after

Secondary Outcomes

Evaluation of predictive value of combined Thoracic Echography (ETC) as assessed T tube Test score difference between patient who succeed or failed the weaning test

Time frame: H0 and 48h after the weaning test

Evaluation of diagnostic value of combined Thoracic Echography (ETC) after failure to weaning test as assessed be ECT scores collected

Time frame: H0, H1 and H48
