Can patients with allergies to anesthetics undergo stellate ganglion block?

Generally, patients allergic to anesthetics should not undergo stellate ganglion block. The detailed explanation is as follows:

Stellate ganglion block is a common nerve block technique primarily used to treat head and neck pain, autonomic nervous system disorders, and similar conditions. Local anesthetic drugs are typically used during this procedure to reduce pain and discomfort.

Anesthetic allergy is one of the contraindications for stellate ganglion block. This technique involves injecting anesthetic into blood vessels. If a patient is allergic to the anesthetic, administration could trigger a severe allergic reaction, including difficulty breathing, anaphylactic shock, and potentially even life-threatening consequences. For patients with allergies requiring treatment that would otherwise be managed by stellate ganglion block, it is recommended to develop alternative treatment plans under a physician's guidance, based on the patient's specific condition and type of illness.

Prior to undergoing a stellate ganglion block, patients should proactively inform their doctor of any allergy history. Additionally, physicians should perform thorough allergy testing before administering the anesthetic injection to ensure patient safety.
