Ultrasonographic Evaluation of the Radial and Ulnar Blood Flow After Radial Arterial Cannulation
Completed
- Conditions
- Radial Artery, Regional Blood Flow
- Interventions
- Device: 20 gauge catheterDevice: 22 gauge catheter
- Registration Number

- Brief Summary
The aim of this randomized study was to compare the impact of two different radial arterial catheters - 20G and 22G - on the changes of diameter, blood flow and velocity of radial artery and ulnar artery after induction of anesthesia and after cannulation.
