Cardiac and Aortic Surgery Clinical Trial
Official title:
Ultrasound Prediction of Radial Arterial Catheterization Failure in Patients Undergoing Cardiac or Aortic Surgery: a Prospective Study
In patients undergoing cardiac or aortic surgery, the placement of a radial KTA is sometimes difficult, the purpose of this study is to do an ultrasound in order to evaluate the diagnostic values of the internal diameter of the radial artery to predict the failure to install the radial KTA.
The Arterial Catheter (KTA) enables continuous measurement of invasive blood pressure in patients with accurate and reliable hemodynamic monitoring. Radial Artery Catheterization is the currently recommended placement site. In patients undergoing cardiac or aortic surgery, placement of a radial KTA is sometimes difficult, with a failure rate of around 15%. It is also a source of local complications and prolongation of the anesthetic duration. There is no predictive diagnostic test for failed radial KTA placement in anesthesia. Accurately predicting the failure of radial catheterization by echography will, in the future, make it possible to offer "at risk" patients an immediate catheterization in an other site as for example brachial site. ;
