传统的神经阻滞与操作者的临床经验密切相关,成功率低、安全性较差.近年超声引导下神经阻滞技术的应用使临床神经阻滞的方式发生了根本性变革,避免了对周围重要组织结构的损伤,减少了并发症的发生几率,提高了阻滞效率.本文就超声引导下神经阻滞术的临床应用进行综述.“,”Traditional nerve block is closely related to clinical experience,with low success rate and poor safety.In recent years,with nerve block guided by ultrasound has been widely applied and rapid development,make fundamental change in the way of clinical nerve block,the technology to avoid the damage on the surrounding important organization structure,improves the success rate of operation,reduced the risk of complications,improve the efficiency of the block.This paper reviews the clinical application of nerve block under ultrasound-guided.
