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

| Active Comparator: Modified dynamic needle tip positioning technique In Modified dynamic needle tip positioning technique, short-axis in-plane is used, needle tip was dynamic guided by ultrasound that added two developing lines on the ultrasonic probe. |
Procedure: Modified dynamic needle tip positioning under ultrasound-guidance
The tip of needle is positioned under ultrasound-guidance using modified dynamic short-axis view.

Outcome Measures
Primary Outcome Measures
- Success rate of the radial artery cannulation at first attempt [intraoperative]
Successful confirmation of the arterial waveform through a pressure monitor at first attempt of the radial artery cannulation
Secondary Outcome Measures
- Time of arterial catheterization [Interval between contact of the ultrasound transducer with the skin and confirmation of an arterial waveform on the monitor, an expected average observation time of 300 seconds]
- Time to first puncture of the artery [Interval between skin penetration of the needle and flashback of blood, an expected average of 200 seconds]
- Time ultrasound imaging [Interval between contact of the ultrasound transducer with the skin and penetration of the needle through the skin, , an expected average of 100 seconds]
- Number of puncture attempts [Up to 5 times, an expected average observation time of 70 seconds]
- Vascular complications in the surgery [postoperative, within 24 hours]
including thrombosis, hematoma, and vasospasm
