With the development of social and economic development, work and the acceleration of the pace of life, the human sleep time began to appear shortened. In the last century, the average sleep time in the 1920s was about 8-9 hours, and in the 21st century, the average sleep time was about 6 hours. A domestic survey in 2013 showed that the more economically developed regions, the shorter the sleep time. Beijing, Shanghai, Guangzhou and Shenzhen and other such developed areas and the developed coastal areas generally sleep less than 6 hours accounted for 40-50%. In 2002, more than 10 international countries jointly conducted a study on insomnia, and the results showed that 31.6% of the respondents reported insomnia in the past month, 17.5% reported “insomnia under the domain”, and the incidence of severe insomnia was 11.6%. The incidence of severe insomnia was 11.6%. Such a high incidence of insomnia has shocked the public with the results of the survey, and insomnia has become a serious medical problem. A good night’s sleep helps to restore energy and strength, so that staff have sufficient energy and strength to carry out their duties. Sleep deprivation not only affects the health and safety of workers and increases the economic burden on individuals and society, but is also associated with chronic pain and the development of mental illness. Sleep deprivation also leads to reduced work capacity and is a potential risk factor for safety, most notably in critical sectors that affect public safety. Studies have shown that bus drivers are at risk for traffic accidents due to sleep deprivation, which can lead to reduced alertness and slower reflexes. Sleep deprivation in older adults is more pronounced than in younger adults. Insomnia is characterized by difficulty falling asleep (sleep onset longer than 30 min), sleep maintenance disorders (≥2 awakenings throughout the night), early awakenings, decreased sleep quality and reduced total sleep time (usually less than 6 h), accompanied by daytime dysfunction. According to the duration of the disease, it is divided into: acute insomnia (duration <1 month); subacute insomnia (duration ≥1 month, <6 months) and chronic insomnia (duration ≥6 months). There are two categories of primary and secondary insomnia according to the etiology. Primary insomnia usually lacks a clear etiology or remains after the exclusion of possible causes of insomnia, and mainly includes three types of psychophysiological insomnia, idiopathic insomnia and subjective insomnia. Secondary insomnia includes insomnia caused by somatic diseases, mental disorders, drug abuse, etc., and insomnia associated with sleep breathing disorders and sleep movement disorders. The diagnosis of insomnia is based on the patient's statement, but there are cases where the patient's complaints are inconsistent with the presentation. The introduction of EEG monitoring technology into insomnia research and treatment can play an objective role in the diagnosis of insomnia, avoiding the inaccurate determination of the condition due to the patient's statements, and the EEG technology can also make an objective determination of the staging of sleep and the type of insomnia. Long-term EEG sleep monitoring allows accurate staging of sleep and classification of the type of insomnia. According to the results of EEG, sleep is divided into 4 periods, namely S1, S2, S3 and S4, which represent the deepening of sleep, and the combined S3 and S4 periods are called slow-wave sleep, the proportion of which reflects the quality of sleep. Deep sleep helps remove the "junk" from the brain and reduces the risk of Alzheimer's disease. As we age, the amount of slow-wave sleep decreases, and in some older adults, slow-wave sleep is even lost. Although clinically used sedative-hypnotic drugs can increase the duration of sleep, most of them shorten the duration of slow-wave sleep and prolong the duration of light sleep. That is, although these drugs for insomnia prolong the total sleep time, they impair the most important sleep component, slow-wave sleep, and do not really improve the quality of sleep. This inevitably leads to dizziness, fatigue, sleepiness, poor concentration, even temporary amnesia (e.g., Valium) and hangovers (e.g., long-acting barbiturates). Sudden discontinuation of the drug may also result in rebound phenomena, such as anxiety, insomnia, excessive dreaming and nightmares. Treatment of persistent insomnia requires multidisciplinary cooperation and the use of targeted treatment methods and tools. Jianxiong An, director of the Department of Anesthesia, Pain and Critical Care Medicine at the Aviation General Hospital of China Medical University, has been exploring and researching for several years and has made great achievements in the treatment of intractable insomnia. He has successfully applied the techniques of stellate ganglion block, triple oxygen autotransfusion therapy, modified non-convulsive electroconvulsive shock and patient self-controlled sleep to the treatment of intractable insomnia and achieved good therapeutic results. Stellate ganglion block has miraculous therapeutic effect on insomnia caused by plant nerve dysfunction, neuroendocrine imbalance, increased excitatory neurotransmitters and decreased inhibitory neurotransmitters in the central nervous system. After stellate ganglion block, the balance of plant nerve function is re-established and the neuroendocrine imbalance is restored; at the same time, the blood flow to the brain is increased after stellate ganglion block, which not only provides more adequate nutrients to the brain, but also transports the waste products produced by brain metabolism smoothly. Triple oxygen autologous blood therapy is a method of mixing the patient's own blood with triple oxygen in a certain ratio and then transfusing it back into the patient. The triple oxygen mixed with blood not only enhances the body's ability to scavenge oxygen free radicals, but also has a two-way regulating effect on the immune system, so that the overly strong/weak immune function is restored to normal and the purpose of treating insomnia is achieved. Another part of insomnia is caused by mental illness, such as depression. For this type of insomnia, modified non-convulsive electroconvulsive therapy (MNT) is given in a targeted manner to treat both the symptoms and the root cause. Modified non-convulsive electroconvulsive therapy is to deliver a small amount of electric current to the brain through special equipment under the condition of close monitoring of vital signs and adequate safety, so that the overactive brain areas can be rested and all areas of the brain can work in a coordinated manner. The innovative concept of "patient-controlled sleep" allows patients to actively participate in the treatment instead of passively receiving it. Patient-controlled sleep is controlled by a special device, which is programmed by the doctor, and when the patient needs it, a certain amount of medication is pumped through a self-control switch. With the combined application of the above-mentioned treatments, insomnia patients show significant improvement in the indicators of sleep time, total sleep time, and deep sleep time, wake up in the morning with high energy, no hangover, high subjective feeling of satisfaction, and objectively patients take significantly less oral medication or even no longer take their previous medication orally. With the economic development of the society, the incidence of insomnia is becoming higher and higher, and it brings serious economic and social burdens and may even endanger production safety. Insomnia, like physical illness, is more important to actively prevent insomnia than to treat it, and good sleep habits can help you stay away from insomnia. Proper outdoor exercise, regular living, optimism, no strong tea, coffee and other beverages before bed, and a quiet sleep environment can all help improve sleep quality.
