Abstract: Noninvasive neuromodulation technique is a non-invasive, safe and convenient research and treatment method, which is mainly regulated by electrical stimulation and magnetic stimulation. In recent years, it has been more and more used in the research and treatment of brain function. It has been confirmed in the regulation of cognitive impairment, depression, anxiety, delirium and insomnia in patients with stroke. Clinical departments such as neurology, rehabilitation department, pain department and other disciplines have widely used this technique of non-invasive neural regulation, but its application in the perioperative period is less, especially for postoperative sleep disorders in patients with general anesthesia. Postoperative sleep disorder is a common and easily neglected complication, which is often manifested as postoperative sleep structure disorder, sleep quality decline, sleep is obviously shortened, and the sleep function of patients with general anesthesia is more likely to be affected. Postoperative sleep disorder includes many influencing factors before, during and after operation, affecting the whole perioperative period and even a few years after discharge.

Key words: noninvasive neuroregulatory techniques, general anesthesia, postoperative management, sleep, postoperative sleep disturbances
