Background
This study assessed the effect of bevel direction on the success rate of ultrasound guided radial artery catheterization.
Methods
A total of 204 patients requiring radial artery catheterization were randomly divided into bevel-up (n = 102) and bevel-down (n = 102) groups. Success rate, cannulation time, and number of attempts were compared groups.
Results
In the bevel-down group, an arterial line was placed on the first attempt in 86 of 102 (84.3%; 95% confidence interval [CI] = 76% to 90%) patients versus 73 of 102 (71.6%; 95% CI = 62.1% to 79.4%) in the bevel-up group (p = 0.028). In the bevel-down group, the mean time to a successful radial arterial cannulation was 33.3 ± 6.3seconds (95% CI = 32.1-34.6) versus 35.9 ± 7.6seconds (95% CI = 34.4-37.2) in the bevel-up group (p = 0.011). The median score was 33.2 and interquartile range [IQR] was 10.9 (30.3-41.2) for the mean cannulation time in the bevel-up group. In the bevel-down group, the mean score was 32.3 (IQR 3.90, 30–33.9) for mean cannulation time. In the bevel-down group, 11 of 102 (7%; 95% CI = 0 to 16%) patients developed a posterior wall puncture versus 22 of 102 ((21.6%; 95% CI = 14.7 to 17.2%) in the bevel-up group.
Conclusion
The bevel-down approach during ultrasound-guided radial artery catheterization exhibited a higher success with fewer complications compared to the bevel-up approach.
