In order to take care of patients with intractable epilepsy, the National Health Insurance Administration has, since the end of 2020 last year, included the entire group of "vagus nerve stimulation" medical materials into the health insurance benefits, which is a boon for epilepsy patients. The principle and effect of vagus nerve stimulation The vagus nerve is a branch of the cranial nerve and is considered a type of autonomic nerve. Controls the secretion of glands in the neck, tracheal constriction and the rhythm of the heart. At the same time, it can also receive visceral messages to the solitary nucleus oblongata, and then project to the thalamus, amygdala and connect with the cerebral cortex. Epilepsy symptoms occur due to the accumulation of postsynaptic excitatory potentials whatsapp list resulting in paroxysmal synchronous depolarization shifts. Vagus nerve stimulation was found more than three decades ago to desynchronize this abnormal potential, thereby preventing seizures. Cyberonics thus designed the NeuroCybernetic Prosthesis System, the first vagus nerve stimulation system, which was applied to the first patient in 1988. In 1997, it was approved by the U.S. Food and Drug Administration (FDA), and it has been widely used in clinical epilepsy treatment. So far, more than 80,000 epilepsy patients around the world have been surgically implanted using this system. The "vagus nerve stimulation" surgery usually involves opening a 5cm wound on the left side of the neck and under the collarbone. The vagus nerve will branch off the left side of the neck and connect to electrodes. A small generator, similar to a heart pacemaker, is placed in the subclavian wound with a wire connected to the vagus nerve electrode on the left side of the neck.
