The posterior antebrachial cutaneous nerve branches from the radial nerve proximal to the elbow and supplies sensation to the posterior aspect of the forearm. With a high-frequency linear transducer, the posterior antebrachial cutaneous nerve was identified in 8 healthy volunteers. Under aseptic conditions and with an ultrasound-guided in-plane technique, 1% lidocaine was injected circumferentially around the nerve. In each participant, the block was successful, and neither incidental blocks of other nerves nor any other complications were observed. These results demonstrate that the posterior antebrachial cutaneous nerve can be blocked to provide anesthesia or analgesia to the posterior forearm.
前臂后皮神经在肘部近端从桡神经分出，为前臂后侧提供感觉。使用高频线性探头，在8名健康志愿者中识别出了前臂后皮神经。在无菌条件下，采用超声引导平面内技术，在神经周围环形注射1%利多卡因。在每位参与者中，阻滞均成功，未观察到其他神经的意外阻滞或任何其他并发症。这些结果表明，可阻滞前臂后皮神经以提供前臂后侧的麻醉或镇痛。
