Abstract

BACKGROUND The ultrasonography-guided technique is superior to the traditional palpation technique for artery cannulation. However, considering the complexity of assembling the ultrasonography machine, this technique has not been extensively used. Here, we compared the ultrasonography-guided technique with the traditional palpation technique in adult patients in the pre-anesthesia room. MATERIAL AND METHODS A total of 66 patients were enrolled and divided into 2 groups: the ultrasonography group and the palpation group. Anesthesiologists then cannulated the radial artery via either method. The primary outcomes included the first-attempt success and total success rates, as well as the cannulation duration and total procedure duration. The secondary outcome was the rate of complications attributable to cannulation. RESULTS Overall, 60 patients were analyzed in the present study. The first-attempt success rate in the ultrasonography group (96.6%) was significantly higher than that in the palpation group (73.3%; P=0.03). There was no significant difference in the cannulation duration and the total procedure duration between the 2 groups. The rate of complications caused by cannulation in 2 groups was similar. CONCLUSIONS The ultrasonography-guided radial artery cannulation technique is more efficient for arterial cannulation in the pre-anesthesia room compared with the traditional palpation method.
