中文摘要: 腘窝坐骨神经阻滞常用于足踝部手术的麻醉与镇痛,但其传统的体表标志辅助神经刺激仪定位法操作繁冗,阻滞成功率低。而且对于已患有神经病变(例如糖尿病周围神经病变)的患者,常规神经阻滞技术的安全性仍不清楚。采用超声引导能明显提高阻滞的成功率、减少局麻药用量及缩短阻滞起效时间等。本文就腘窝坐骨神经阻滞中常见的几个焦点问题——针尖位置、穿刺平面、穿刺入路、局麻药的扩散方式及注射用量、浓度等进行了探讨,以期为临床应用提供参考。
Abstract:Popliteal sciatic nerve block is commonly used for anesthesia and analgesia in foot and ankle surgery. The traditional localization method of body surface marker assisted neurostimulator is cumbersome and has a low success rate of blocking. Moreover, the safety of conventional nerve block techniques in patients with pre-existing neuropathy (e.g., diabetic peripheral neuropathy) remains unclear. The success rate of blockage can be greatly enhanced through the utilization of ultrasound guidance,reduce the volume of local anesthetic and shorten the onset time. In this paper,several common focal issues in popliteal sciatic nerve block were discussed,such as the position of the needle tip,the puncture plane,puncture path,the diffusion mode of local anesthetics and the injection volume and concentration,in order to provide a reference for clinical application.
