Ultrasonographic Evaluation of the Radial and Ulnar Blood Flow After Radial Arterial Cannulation

Severance Hospital80 enrolled

Overview

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.
