Radial Artery, Regional Blood Flow
Conditions
Keywords
radial artery, ulnar artery, catheterization, regional blood flow
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.
Interventions
radial artery cannulation using 22 gauge catheter
radial artery cannulation using 20 gauge catheter
