Tips for a Cervical Sympathetic Block
A cervical sympathetic block is performed to manage patients with various pain conditions, including complex regional pain syndrome and peripheral vascular disease.
We wanted to share these 3 tips to successfully perform a cervical sympathetic block:
- Place the transducer at the C6 level to allow cross-sectional visualization of the transverse process and anterior tubercle of C6, longus colli muscle and prevertebral fascia, and carotid artery and thyroid gland.
- A prescan is important in planning the needle path as the presence of the esophagus and inferior thyroidal artery may obviate the needle path between the carotid artery and trachea.
- Direct the needle to the prevertebral fascia between the carotid artery and the tip of the C6 anterior tubercle to inject 5 mL of local anesthetic.
