Arterial Catheterization, Coronary Artery Disease, Ultrasound
Conditions
Brief summary
Conventionally, long-axis in-plane (LA-IP), short-axis out-of-plane (SA-OOP) and dynamic needle tip positioning based on SA-OOP views are commonly used method to image the target vessel during cannulation under US guidance. A modified SA-OOP that add developing line on the ultrasonic probe improve the success rate of cannula insertion into the radial artery on the first attempt.
Interventions
PROCEDUREModified dynamic needle tip positioning under ultrasound-guidance
The tip of needle is positioned under ultrasound-guidance using modified dynamic short-axis view.
PROCEDURELong-axis technique
The tip of needle is positioned under ultrasound-guidance using conventional long-axis in-plane view.
