SSdopler: Value of Cardiac Output Monitoring by Supra-sternal Doppler/Echocardiography in Intensive Care Unit
Study Details
Study Description
Brief Summary
The aim of this study is to evaluate the concordance between the measurement of cardiac blood flow by non-invasive supra sternal ultrasound and the measurements performed by invasive monitoring in intensive care patients already equipped with an invasive monitoring. This invasive monitoring consists of catheters used to measure the cardiac output allowing the supply of organs and is installed when there is need to monitor the blood flow in different hemodynamic reasons. The patient's care will not be modified, the study just requires a supplementary measure in an exam already perform in the standard care. The principal hypothesis is that we can show a concordance between this non-invasive measure and the standard invasive monitoring.

Detailed Description
The aim of this study is to evaluate the concordance between the measurement of cardiac output by non-invasive supra sternal ultrasound and the measurements performed by invasive monitoring (trans pulmonary thermodilution or right heart catheterization) in intensive care patients already equipped with an invasive monitoring. Cross sectional study was performed in Reims university hospital. Patients who will be included in this study are patients who already have an invasive cardiac output monitoring such as trans pulmonary thermodilution or right heart catheterization for many reason as septic shock, cardiogenic shock or any shock state. Cardiac output will be measured by supra-sternal and transthoracic echography and by invasive monitoring (trans pulmonary thermodilution or right heart catheterization). Intra-class correlation coefficient will be calculated to assess the concordance between the measurement of cardiac blood flow by non-invasive supra sternal ultrasound and the measurements performed by invasive monitoring.
