Visualization with the ultrasound will reveal structures surrounding the stellate ganglion; these include the carotid artery (an important landmark), sternocleidomastoid, internal jugular, thyroid gland, vertebral artery, esophagus, pleura, nerve roots, and the longus colli muscle (another important landmark). The target location lies in the facial plane anterior to the longus colli muscle, where the stellate ganglion is observed. After subcutaneous local anesthetic administration, using an in-plane approach, guide a 21- or 22-gauge needle to the target location. After negative aspiration for blood, air, and CSF, as well as close patient monitoring, inject 5–10 mL of 1% lidocaine or 0.25% bupivacaine with or without a steroid in small aliquots under real-time ultrasonography while observing for the spread of injectate volume along the appropriate fascial plane.

超声可视化将显示星状神经节周围结构：颈动脉（重要标志）、胸锁乳突肌、颈内动脉、甲状腺、椎动脉、食道、胸膜、神经根和颈长肌（另一重要标志）。靶点位于颈长肌前方的肌筋膜平面（译者注：原文是facial，译者认为是fascial），在此可观察到星状神经节。皮下注射局麻药，使用平面内入路，将21或22号针置入到目标位置。回抽血、脑脊液和空气阴性后，在密切监测下小剂量多次注射1%利多卡因或0.25%布比卡因共5～10ml，含或不含类固醇。超声下实时观察药液沿适当筋膜平面的扩散情况。

理解的对吗？谢谢
