桡动脉穿刺置管技术是麻醉监测使用的临床基本操作技能。传统方法主要依靠医生触及患者脉搏搏动进行定位穿刺。由于这种近乎盲探的穿刺法完全依赖医生的手指感觉判断定向,对于初学者来说,准确性差、成功率低、耗时长、并发症多,因此较难掌握,教学指导非常困难。超声技术能清晰探测血管位置及走向,用超声定位明确血管位置及走向并标记于体表,便于对进修医生进行教学指导,提高穿刺成功率,减少对组织及血管的损伤,提高工作效率,
Radial artery catheterization is a clinical basic operational skill used in anesthesia monitoring. The traditional method mainly rely on the doctor to touch the pulse of the patient to locate the puncture. Because this kind of almost blind exploration of the puncture method depends entirely on the doctor’s finger feeling to judge the orientation, for beginners, the accuracy is poor, the success rate is low, time-consuming, complications and more difficult to grasp, instructional guidance is very difficult. Ultrasound technology can clearly detect the location and direction of blood vessels, using ultrasound to locate the location and direction of blood vessels and mark it on the surface of the body, which is convenient for teaching doctors to improve the puncture success rate, reduce the damage to tissues and blood vessels, improve work efficiency,
