The goal of this study was to evaluate in patients with peripheral arterial disease (PAD) whether ultrasound-guided radial artery catheterization decreased procedural time and number of attempts compared with the traditional palpation technique.
Ultrasonography was evaluated for arte- rial catheterization after the traditional palpation tech- nique was unsuccessful in 480 seconds in 10 patients with PAD. The vascular access was performed by a single anesthesiologist. The successful catheterization time and the number of attempts were recorded. We also measured the diameter of the radial artery, the skin-to-artery distance, and the distance between the linear probe and puncture site.
The mean overall time per patient for catheter insertion was 220.0?112.6 sec in the ultra- sound group vs. 480 sec in the palpation group (P= 0.0029). The mean number of attempts was 1.30?0.48 in the ultrasound group vs. 4.50?0.53 in the palpation group (P = 0.0024). All catheterizations were success- ful, and no failure was encountered in the ultrasound group.
Ultrasound-guided radial artery cath- eterization took less time to establish the arterial line, and it reduced the number of attempts when com- pared with the palpation technique.
本研究的目的是评估在周围动脉疾病（PAD）患者中，与传统触诊技术相比，超声引导下桡动脉置管是否能减少操作时间和尝试次数。
在10例PAD患者中，当传统触诊技术在480秒内未成功时，对超声引导下的动脉置管进行评估。血管通路由一名麻醉医生完成。记录成功置管时间和尝试次数。我们还测量了桡动脉直径、皮肤至动脉距离以及线性探头与穿刺部位之间的距离。
超声组患者每次置管的平均总时间为220.0±112.6秒，而触诊组为480秒（P = 0.0029）。超声组的平均尝试次数为1.30±0.48次，触诊组为4.50±0.53次（P = 0.0024）。所有置管均成功，超声组未出现失败情况。
与触诊技术相比，超声引导下桡动脉置管建立动脉通路所需时间更短，且尝试次数更少。
