Stellate ganglion block has been used to treat a number of disorders of the head, neck, upper extremities, shoulder, heart and lungs due to the inhibition of preganglionic and postganglionic nerve fiber function at the block site and the inhibition of cardiovascular motility, glandular secretion, muscle tension, bronchoconstriction and nociceptive transmission innervated by sympathetic nerve fibers in the distribution area. In recent years, further studies on the mechanism of stellate ganglion block have shown that, in addition to the above peripheral effects, stellate ganglion block also has a regulatory effect on the function of the autonomic nervous system, endocrine system and immune system through hypothalamic mechanisms, thus helping to maintain the stability of the body’s internal environment. Therefore, stellate ganglion block has been widely used in the treatment of many autonomic dysfunctional diseases. The indications are as follows: 1. Head and face Migraine, tension headache, cluster headache, cerebrovascular diseases (such as cerebrovascular spasm, embolism and sequelae of traumatic brain injury), retinal vascular embolism, optic neuritis, corneal ulcer, glaucoma, facial nerve palsy, atypical facial neuralgia, trigeminal neuralgia, post-herpetic neuralgia, temporomandibular joint syndrome, masticatory muscle spasm, sudden deafness, allergic rhinitis Allergic rhinitis, atrophic rhinitis, rhinocystitis, tinnitus, etc. 2.Cervical, nasal and upper limb disorders Cervical spondylosis, frozen shoulder, thoracic outlet syndrome, upper limb vascular disease, brachial plexus neuropathy, phantom limb pain, post-band syndrome neuralgia, post-mastectomy syndrome, etc. 3.Respiratory and circulatory system disorders Asthma, bronchitis, pulmonary edema, angina pectoris, cardiac neurosis, etc. 4.Gynecological disorders dysmenorrhea, menopausal syndrome, premenstrual tension, autonomic dysfunction after hysterectomy or oophorectomy, female infertility, etc. 5.Digestive and urological diseases Allergic colitis, ulcerative colitis, gastrointestinal dysfunction, impotence, neurogenic urinary frequency, male infertility, etc. 6, systemic diseases Indeterminate cert, reflex sympathetic dystrophy, primary hypertension, primary hypotension, postural hypotension, hyperthyroidism, hypothyroidism, skin pruritus, chronic fatigue syndrome, insomnia, hyperhidrosis, frostbite, etc.
