我们对33具(66侧)男成尸进行了避免肌间沟臂丛阻滞麻醉产生并发症的解剖学研究。观测了臂丛上干中点至膈神经、迷走神经、颈部交感干、第六颈椎椎间孔外缘、喉返神经的距离,为临床提供掌握穿刺方向和穿刺深度以及穿刺至臂丛上干时需避免其邻近神经麻痹的解剖学数据。 We conducted an anatomical study of 33 adult (66 sides) male cadavers to avoid complications resulting from muscular dural plexus block anesthesia. Observed from the dry reach the brachial plexus to the phrenic nerve, vagus nerve, cervical sympathetic, the sixth cervical intervertebral foramen, the return of the recurrent laryngeal nerve, providing clinical guidance for the direction and depth of puncture and puncture to the brachial plexus dry Anatomy of paralysis of adjacent nerves need to be avoided.
