[摘要] 近年来，随着高频高清晰超声设备的出现以及超声探头的不断改良，超声引导下行桡动脉穿刺置管在急危重症抢救和介入治疗中的应用呈上升趋势，相关研究越来越多。因动脉穿刺的相关并发症比静脉穿刺的更为严重，所以如何将动脉穿刺并发症降到最少是目前研究的重点；而超声技术在桡动脉穿刺置管中的应用已被证明较传统盲穿方法有更多优势。

    [Abstract] In recent years， with the emergence of high-frequency high-resolution ultrasonic apparatus and improvement of ultrasonic probe， the application of ultrasound-guided radial artery cannulation in rescue and intervention treatment of patients with emergency and severe illness is increasing. Since artery puncture may lead to more severe complications compared with the venous puncture ......
