Abstract: Pericapsular Nerve Group （PENG） block of hip joint is a new regional anesthesia method of nerve block. It was first used for anesthesia in hip joint surgery and perioperative analgesia, and has gradually been applied to lower limb amputation, varicose ligation and stripping of great saphenous vein, and resection of medial thigh mass and other lower limb operations. PENG block can block obturator nerve simply and almost perfectly, produce good perioperative analgesia, reduce the demand for opioids and related adverse reactions, and do not affect the muscle strength of lower limbs, which makes many experts at home and abroad pay more and more attention to it in recent years.This paper reviews the advances in clinical research on the anatomical basis of PENG block, the analysis of B-ultrasound-guided anesthesia technology and its effect in lower extremity surgery. This paper reviews the advances in clinical research on the anatomical basis of PENG block, the analysis of B-ultrasound-guided anesthesia technology and its effect in lower extremity surgery.

摘要： 髋关节囊周神经（PENG）阻滞是一种新型的神经阻滞区域麻醉方法。它最早在髋关节手术麻醉和围术期镇痛方面应用,现在已逐渐应用于下肢截肢手术、大隐静脉曲张结扎剥离术以及大腿内侧肿物切除术等下肢手术。由于PENG阻滞能操作简单且几乎完善地将闭孔神经阻滞,产生良好的围术期镇痛,减少阿片类药物需求和相关不良反应,且不影响下肢肌力,使得近几年国内外不少专家对其研究热度日益高涨。该文针对PENG阻滞的解剖基础、B超引导下麻醉技术分析及其应用于下肢手术中的效果临床研究进展予以综述。
