Modified Dynamic Needle Tip Positioning vs Conventional Long-axis In-plane in Radial Artery Cannulation

Qianfoshan Hospital

Status: Completed

Conditions: Coronary Artery Disease; Arterial Catheterization; Ultrasound

Treatments: Procedure: Long-axis technique; Procedure: Modified dynamic needle tip positioning under ultrasound-guidance

Study type: Interventional

Funder types: Other

Identifiers

NCT05687370

YXLL-KY-2022(104)

Details and patient eligibility

About

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.
