闭孔神经阻滞的研究进展

背景闭孔神经阻滞（obturator nerve block，ONB）可用于缓解大腿内收肌痉挛及髋关节疼痛、抑制经尿道膀胱肿瘤电切术中闭孔神经反射等。近年来，随着人们对神经阻滞麻醉的再度关注，ONB的应用与研究也随之增多。目的概述及评价ONB适应证及穿刺方法，为临床及研究工作提供参考。内容阐述ONB的适应证，荟萃分析ONB的不同穿刺入路及方法。趋向随着ONB临床应用的不断普及，更具优势的阻滞方法也会不断涌现。

The development of obturator nerve block

Background Obturator nerve block（ONB） can be used to treat hip joint pain and relief adductor muscle spasm, A selective ONB still remains the safest and most effective alternative to suppress the obturator reflex during transurethral resection of bladder tumor on the lateral bladder wall. Its research and application increased in recent years along with the renewed interest in regional anesthesia. Objective To summarize the indications and techniques of ONB for clinical and research reference. Content Indications and different routes of puncture techniques of ONB, including their evaluations, are elucidated in this review. Trend New block methods with more advantages will occur along with the increasing popularity of its application.
