Echography to Predict Radial Artery Catheterization Failure (EPRAC) (EPRAC)
Ultrasound Prediction of Radial Arterial Catheterization Failure in Patients Undergoing Cardiac or Aortic Surgery: a Prospective Study
調査の概要
状態
条件
詳細な説明
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.

Failure to insert a radial artery catheter (KTA) by the nurse anesthesiologists
時間枠:Day 1
|
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.
