Study Description
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.

Condition or disease Intervention/treatment
Radial Artery, Regional Blood Flow Device: 22 gauge catheter Device: 20 gauge catheter

Study Design

Study Type : Observational
Actual Enrollment : 80 participants
Observational Model: Case Control
Time Perspective: Prospective
Study Start Date : May 2010
Primary Completion Date : September 2010
Study Completion Date : September 2010
Groups and Cohorts

Group/Cohort Intervention/treatment
20 gauge group Device: 20 gauge catheter
radial artery cannulation using 20 gauge catheter
22 gauge group Device: 22 gauge catheter
radial artery cannulation using 22 gauge catheter


Outcome Measures

Primary Outcome Measures :
  1. Radial artery diameter and blood flow before and after cannulation [ Time Frame: 30 min ]
  2. Ulnar artery diameter and blood flow before and after cannulation [ Time Frame: 30 min ]

Secondary Outcome Measures :
  1. The differences of radial artery diameter and blood flow after cannulation between catheter gauge(20- and 22-G) [ Time Frame: 30 min ]
  2. The differences of ulnar artery diameter and blood flow after cannulation between catheter gauge(20- and 22-G) [ Time Frame: 30 min ]
