【摘要】目的 评价经腋路贯穿动脉两点注药法臂丛阻滞的麻醉效果。方法 采用经腋路贯穿动脉两点注药法臂丛阻滞对40例行上肢前臂和手部手术的患者实施阻滞麻醉，观察镇痛及阻滞效果，起效时间及局麻药中毒，神经损伤，血管刺伤和血肿等并发症。结果 阻滞起效时间为(8.5±3.0)min，神经阻滞效果评级达Ⅰ级的35例，占87.5%，Ⅱ级3例，占7.5%，Ⅲ级1例，占2.5%，Ⅳ级1例，占2.5%。有3例出现误穿血管，但无血肿，无一例出现中毒反应，神经损伤等并发症。结论 经腋路贯穿动脉两点注药法臂丛阻滞定位准确性高，可使局麻药沿腋动脉两侧扩散，能大大提高阻滞成功率。

    【Abstract】Objective To evaluate the axillary artery runs through the two injection methods brachial plexus block anesthesia. Methods The axillary artery runs through the two injection brachial plexus block method in 40 routine upper forearm and hand surgery for patients with anesthesia, analgesia and block effects observed, onset time and local anesthetic toxicity, nerve injury, vascular puncture, and hematoma complications. Results The block onset time (8.5±3.0) min, nerve block effect rating of grade Ⅰ, 35 cases, accounting for 87.5%, Ⅱ grade 3 patients, accounting for 7.5%, Ⅲ level 1 cases, accounting for 2.5%, Ⅳ Level 1 cases, accounting for 2.5%. 3 patients had mistakenly wearing blood vessels, but no hematoma, with no toxic reaction occurs, nerve injury. Conclusion The axillary artery runs through the two injection method with high accuracy positioning brachial plexus block, local anesthetic can spread along both sides of the axillary artery, can greatly improve the block success rate. ......
