The therapeutic effect of stellate ganglion block is to maintain the stability of the body’s internal environment by regulating the hypothalamus, so that the plant nervous function, endocrine function and immune function are normalized, while the cardiovascular movement, glandular secretion, muscle tension, bronchial contraction and nociceptive conduction innervated by the preganglionic and postganglionic fibers at the block site are also inhibited. As research into the function of the stellate ganglion progresses, stellate ganglion block may become an important clinical treatment in the 21st century. The indications for stellate ganglion block are as follows: 1. systemic diseases: disorders of phytodysfunction, endocrine disorders and immune disorders, neurasthenia, intractable insomnia and dreaminess, paroxysmal sleep, headache and vertigo, irritability, hyperhidrosis, cold limbs, dryness, primary hypertension or hypotension, hyper- or hypothyroidism, diabetes, anorexia or over-eating, postural blood pressure abnormalities, systemic ringworm, intractable acne, neurodermatitis, pruritus, post-stroke pain, herpes zoster pain, phantom limb pain, amputation pain, post-operative pain at the original lesion or wound pain after healing, indeterminate aging syndrome, chronic fatigue syndrome, sub-health state, drug dependence, schizophrenic anxiety disorder, etc. Head and facial disorders: headache (migraine, vascular headache, tension headache), seborrheic dermatitis, alopecia areata, facial nerve palsy, trigeminal neuralgia, optic neuritis, glaucoma, visual fatigue, refractive error, mosquito flying, sudden deafness and tinnitus, Meniere’s disease, benign episodic vertigo, chronic rhinitis and nasal congestion, sudden olfactory abnormalities, chronic pharyngitis and abnormal sensory disorders in the throat, post-extraction tooth pain, tongue pain, oral cavity, etc. Pain, tongue pain, oral mucosal dryness, etc. 3.Somatic limb diseases: cervical spondylosis, cervical-shoulder-arm syndrome, periarthritis of the shoulder joint, painful redness and swelling of the extremities, cyanosis, thrombo-occlusive vasculitis, osteophytes, degenerative osteoarthrosis, lumbar disc protrusion, lumbar leg pain, etc. 4, visceral diseases: cardiac neurosis, sinus tachycardia or bradycardia, arrhythmia, myocardial infarction angina pectoris, chronic bronchitis bronchial asthma, hyperventilation syndrome, chronic ulcerative colitis, gastritis, gastric ulcer, Crohn’s disease, habitual constipation or diarrhea, 5, genitourinary diseases: premenstrual tension, dysmenorrhea, menstrual abnormalities, menopausal syndrome, after breast or uterine surgery Phytodysfunction, male/female dysfunction, infertility, neurogenic enuresis, nocturnal enuresis, chronic prostatitis, etc.
