About this study
Official title: Comparison of Short-Axis and Long-Axis Approaches for Ultrasound-Guided Radial Artery Cannulation: The Effect of Radial Artery Depth on Technique Selection-A Randomized Controlled Trial
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Short-Axis/Out-of-Plane Radial Artery CannulationProcedure or surgery
Ultrasound-guided radial artery cannulation will be performed using the short-axis/out-of-plane approach. The radial artery will be visualized in the short-axis view, and the needle will be advanced using an out-of-plane technique until successful arterial cannulation.
Long-Axis/In-Plane Radial Artery CannulationProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| Short-Axis/Out-of-Plane Approach | Experimental | Participants assigned to this group will undergo ultrasound-guided radial artery cannulation using the short-axis/out-of-plane approach. Receives: Procedure: Short-Axis/Out-of-Plane Radial Artery Cannulation |
| Long-Axis/In-Plane Approach | Active comparator | Participants assigned to this group will undergo ultrasound-guided radial artery cannulation using the long-axis/in-plane approach. Receives: Procedure: Long-Axis/In-Plane Radial Artery Cannulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: During the radial artery cannulation procedure
Secondary outcomes (1)
First-Attempt Cannulation Success

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
