目的：应用局部麻醉剂麻醉颈丛皮神经以缓解疼痛或进行小手术。了解这些神经的变化对于麻醉师对特定神经进行有效麻醉是很重要的。因此，这项研究的目的是寻找颈部皮神经出现模式的变化，并通过使用表面标志来定位颈部的神经点。材料与方法：对16具胎儿尸体（共32具）进行颈部解剖。根据胎儿的年龄分为2组：1组（13-24周）和2组（24-38周）。解剖颈皮神经。两组均测量了神经点的位置。结果：对测量结果进行了统计分析。1组神经点距外耳道（EAM）的平均左右距离分别为2.06cm和1.85cm， 2组神经点距左右距离分别为2.32cm和2.08cm。1组左右两侧神经点距锁骨的平均距离为1.85cm， 2组左右两侧神经点距锁骨的平均距离为2.67cm和2.62cm。记录并拍摄了从神经点出现的皮神经的变化。结论：这些标志有助于麻醉师定位神经点。当麻醉师在神经阻滞期间对特定神经进行麻醉时，他们应该知道颈丛分支的这些变化。
Objective: The cutaneous nerves from the cervical plexuses are anaesthetized by using local anaesthetics for pain relief or when minor surgical operations are performed. Knowing the variations in these nerves is important for anaestheticists to administer an effective anaesthesia to a particular nerve. So, the aim of this study was to look for the variations in the emerging patterns of the cervical cutaneous nerves in the neck and to locate the nerve point in the neck by using the superficial landmarks.Materials and Methods: The neck was dissected in 16 foetal cadavers (total 32). The foetuses were divided into 2 groups, depending upon their ages-group 1 (13-24wks) and group 2 (24-38wks). The cervical cutaneous nerves were dissected. Measurements for locating the nerve point, were taken in both the groups.Results: The statistical analysis of the measurements was done. In group 1, the mean distances of the nerve point from the External Acoustic Meatus (EAM), on the right and left sides, were 2.06cm and 1.85cm and in group 2, the distances on the right and left sides were 2.32cm and 2.08cm. The mean distance of the nerve point from the clavicle in group 1, on both the right and the left sides was 1.85cm, and in group 2, the mean distances on the right and left sides were 2.67cm and 2.62cm. The variations in the cutaneous nerves which emerged from the nerve point were recorded and photographed.Conclusion: These landmarks will help the anaestheticists in locating the nerve point. These variations in the branches of the cervical plexus should be known to the anaestheticists while they give anaesthesia to a particular nerve during a nerve block.
