Stellate ganglion block is not a disease, but a treatment, a minimally invasive treatment commonly used in pain clinics. The general procedure is to inject local anesthetic drugs into the loose connective tissue containing the stellate ganglion to achieve the effect of nerve block of the cervical sympathetic trunk, cervical sympathetic ganglion with the preganglionic and postganglionic nerves and their innervation range. It is mainly used for arterial cervical spondylosis and sympathetic cervical spondylosis. Of course, it is also sometimes applied to treat hypertension and hypotension, hypothermia, hyperhidrosis, weight gain or loss, hyper- or hypothyroidism, narcolepsy, and over-eating disorders. One of them is the stellate ganglion, one of the sympathetic ganglia in the neck. It consists mainly of the inferior cervical ganglion and the 1st thoracic sympathetic ganglion. The function is to innervate the eyelid muscle, pupil opening muscle, capillary smooth muscle and sweat gland. The sympathetic fibers from the stellate ganglion are also involved in forming the cardiac plexus, which is involved in regulating the activity of the heart and blood vessels. Therefore, blockade of the stellate ganglion can effectively improve and treat certain clinical symptoms. It is a promising surgical technique for the treatment of a wide range of diseases, and it can bring many benefits to patients in the future.
