  Purpose

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.


Condition Intervention
Radial Artery, Regional Blood Flow
Device: 22 gauge catheter
Device: 20 gauge catheter

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective

Further study details as provided by Severance Hospital:

Primary Outcome Measures:
  • Radial artery diameter and blood flow before and after cannulation [ Time Frame: 30 min ] [ Designated as safety issue: No ]
  • Ulnar artery diameter and blood flow before and after cannulation [ Time Frame: 30 min ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The differences of radial artery diameter and blood flow after cannulation between catheter gauge(20- and 22-G) [ Time Frame: 30 min ] [ Designated as safety issue: No ]
  • The differences of ulnar artery diameter and blood flow after cannulation between catheter gauge(20- and 22-G) [ Time Frame: 30 min ] [ Designated as safety issue: No ]
