Short-Axis Versus Long-Axis Ultrasound-Guided Radial Artery Cannulation

Saglik Bilimleri Universitesi Gazi Yasargil Training and Research Hospital144 enrolled

Overview

This randomized controlled study aims to compare short-axis/out-of-plane and long-axis/in-plane ultrasound-guided techniques for radial artery cannulation in adult patients undergoing elective surgery. The study will also investigate whether the depth of the radial artery from the skin is associated with cannulation success and may help guide the selection of the ultrasound-guided cannulation technique. Participants will be randomly assigned to either the short-axis/out-of-plane group or the long-axis/in-plane group. Radial artery depth will be measured using ultrasound before cannulation. The two techniques will be compared in terms of cannulation success, including first-attempt success, number of punctures and needle redirections, time to successful cannulation, failed cannulation, and procedure-related complications.

Conditions

Radial Artery Cannulation

Interventions

Long-Axis/In-Plane Radial Artery CannulationPROCEDURE

Ultrasound-guided radial artery cannulation will be performed using the long-axis/in-plane approach. The radial artery will be visualized in the long-axis view, and the needle will be advanced using an in-plane technique until successful arterial cannulation.

Outcomes

Primary Outcomes

Success Rate of Short-Axis/Out-of-Plane Versus Long-Axis/In-Plane Radial Artery Cannulation

The success rates of ultrasound-guided radial artery cannulation using the short-axis/out-of-plane and long-axis/in-plane approaches will be compared. Successful cannulation is defined according to the study protocol as successful radial artery catheter placement within the predefined procedural criteria.

Time frame: During the radial artery cannulation procedure
