BACKGROUND
A selective blocking method for the cervical plexus and the cervical sympathetic trunk has not yet been established.
METHODS
We performed a detailed examination of the neck anatomy using 28 cadavers. The pattern of local anesthetic distribution after injection in 2 healthy volunteers was imaged using computed tomographic scan.
RESULTS
The deep cervical plexus was located in the groove between the longus capitis and scalenus medius muscles. The cervical sympathetic trunk was located on the anteromedial surface of the longus capitis. Although anesthetic injected into the longus capitis was confined to the muscle, it infiltrated into neighboring structures including the C2 to C5 roots and sympathetic trunk.
CONCLUSIONS
The longus capitis muscle is a suitable landmark for blocking the cervical plexus and trunk.
背景
尚未建立一种选择性阻滞颈丛和颈交感干的方法。
方法
我们使用 28 具尸体对颈部解剖结构进行了详细检查。对 2 名健康志愿者注射局部麻醉剂后，使用计算机断层扫描成像技术对其分布模式进行了成像。
结果
深部颈丛位于头长肌和中斜角肌之间的沟内。颈交感干位于头长肌的前内表面。尽管注入头长肌的麻醉剂局限于肌肉，但它会渗透到包括 C2 到 C5 神经根和交感干在内的邻近结构中。
结论
头长肌是阻滞颈丛和干的合适标志。
