Ultrasound‐guidance of radial artery catheter insertion improves the first attempt success and reduces the occurrence of hematomas. Needle‐tracking devices optimize needle‐ultrasound beam alignment by displaying in real‐time the needle tip position. We compared the median time need by experienced physicians to achieve radial artery puncture using either a conventional ultrasonography device (CUD) or a magnetic needle‐tracking ultrasound device (MUD) in a simulation training arm model. Methods Fifty experienced residents and physicians performed two punctures in randomized order with the CUD and the MUD. The primary outcome was puncture duration; the secondary outcomes were puncture success, rate of accidental vein puncture, and practitioner's comfort (subjective scale 0‐10). Results The median [lower‐upper quartile] puncture time was 10 [6‐14] seconds when using CUD and 4 [3‐7] seconds when using MUD ( P < .01). In the multivariate analysis, MUD use was associated with decreased puncture duration whatever the puncture order (OR 1.13 [1.07‐1.20], P < .01). The participants performed 99 (99%) successful punctures: 50 with the MUD (100%) and 49 with the CUD (98%). There was no accidental venous puncture. The practitioner's comfort level was 6.5 [6, 7] with the CUD and 8 [7‐9] with the MUD ( P < .01). Conclusion MUD reduced radial artery puncture time and improved physician comfort in a simulation training arm model.
