NCT04730479 - Echography to Predict Radial Artery Catheterization Failure (EPRAC) | Crick

Overview

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.

Outcomes

Primary Outcomes

Failure to insert a radial artery catheter (KTA) by the nurse anesthesiologists

Failure to insert the radial KTA by the nurse anesthesiologist defined as follows: ≥ 3 punctures (by the nurse anesthetist) or need to change of doctor operator (nurse anesthesiologist to Anesthesiologist - Resuscitator) or change of puncture site (radial to radial contralateral or other site). All professionals involved are blinded to the echographic measures of the radial artery.

Time frame: Day 1

Secondary Outcomes

Internal radial artery diameter

Measured on echographic exam. Image acquisition done by an independent nurse anesthesist (not involved in the management of the same patient). Radial artery diameter measured on these images, later, by an anaesthesiologist-Resuscitator physician.

Time frame: Day 1

External radial artery diameter

Measured on echographic exam. Image acquisition done by an independent nurse anesthesist (not involved in the management of the same patient). Radial artery diameter measured on these images, later, by an anaesthesiologist-Resuscitator physician.

Time frame: Day 1

Internal area of the radial artery

Measured on echographic exam. Image acquisition done by an independent nurse anesthesist (not involved in the management of the same patient). Radial artery diameter measured on these images, later, by an anaesthesiologist-Resuscitator physician.

Time frame: Day 1

External area of the radial artery

Measured on echographic exam. Image acquisition done by an independent nurse anesthesist (not involved in the management of the same patient). Radial artery diameter measured on these images, later, by an anaesthesiologist-Resuscitator physician.

Time frame: Day 1
