目的累积国人的解剖学资料，给临床实施臂丛麻醉提供较可靠的解剖基础。资料和方法在４４具成人尸体（男２６具、女８具）上使用层次解剖法，共测量了８８侧斜角肌间隙。结果该间隙的最高点距锁骨上缘中点的距离为ｘ＝５．３６ｃｍ；从锁骨的胸骨端至前斜角肌后缘的距离为ｘ＝５．４９ｃｍ，至中斜角肌前缘的距离是ｘ＝６．６６ｃｍ；锁骨下动脉在前斜角肌后缘的最高点距锁骨上缘的中点为ｘ＝２．０９ｃｍ，臂丛上干距锁骨上缘中点为ｘ＝３．６６ｃｍ，中干距锁骨上缘中点为ｘ＝２．８４ｃｍ；臂丛神经的走行方向与锁骨水平方向形成向前内侧开放ｘ＝６１．５２°的夹角。结论本研究对临床实施臂丛麻醉有一定的指导作用。
Objective To accumulate anatomical data of Chinese people and provide more reliable anatomical basis for clinical implementation of brachial plexus anesthesia. MATERIALS AND METHODS Hierarchical anatomy was used on 44 adult cadavers (26 males and 8 females) and a total of 88 scalene scalene intervals were measured. Results The distance from the highest point of the gap to the midpoint of the upper clavicle was x = 5.36 cm. The distance from the sternum of the clavicle to the posterior edge of the anterior scalene was x = 5.49 cm, The distance between the subclavian artery and the upper edge of the anterior scalene muscle was x = 2.09 cm. The midpoint of the upper margin of the supraclavicular margin of the brachial plexus was x = 3. 66cm, in the middle of the distance from the upper edge of the clavicle x = 2.84cm; brachial plexus walking direction and the level of the medial clavicle to form a forward x open angle of 61.52 °. Conclusion The study of brachial plexus anesthesia in clinical practice has some guidance.
