Active Comparator: direct palpation
Radial artery catheter insertion will be conducted by direct palpation and use of anatomic knowledge by the Anesthesiologist.
Device: Direct Palpation-guided Radial Artery Catheter insertion
Active Comparator: Ultrasound
Radial artery catheter insertion will be conducted by ultrasound guidance. A Sono-site ilook 25 Ultrasound (Sono-site, Inc., Bothell, WA, USA) with a 10-5 MHz linear array ultrasound transducer will be used.
At the discretion on the Anesthesiologist, an out-of-plane (i.e. needle plane at right angles to ultrasound plane) will be used. Colour flow doppler may also be used to identify the artery if necessary.
Device: Ultrasound-guided Radial Artery Catheter Insertion
- Time to Successful Radial Arterial Catheterization [ Time Frame: up to 5 minutes ]The time to successful radial arterial catheterization was defined as time zero to time of placement. Time zero for the DP group began when the anesthesiologist's fingers were placed on the patient with the purpose of palpating the artery. Time zero for the US group began when the US transducer was first placed on the patient's skin for the purpose of identifying the radial artery. Time to placement was defined as the interval from time zero until the time at which an arterial tracing was viewed on the monitor.
- Number of Attempts [ Time Frame: up to 5 minutes ]An attempt was defined as a new purposeful penetration of the skin with the needle (i.e., following complete withdrawal of the needle from the skin).
- Number of Re-directions [ Time Frame: up to 5 minutes ]A re-direct was defined as the needle being purposefully withdrawn at least 5 mm and re-directed (but not removed from the skin entirely).
- Complication Rate (Hematoma) [ Time Frame: up to 5 minutes ]A hematoma was defined a collection of blood or formation of a bruise surrounding the site of radial artery catheterization
