First, the history of the development of pain medicine As early as the 1920s, the United States, anesthesiologists have opened pain clinics. 1950s, many foreign hospitals have opened pain departments, the establishment of pain research and treatment centers. With the establishment of the International Academy of Pain in 1976, it marked the time when medical personnel who were passionate about pain medicine could independently research and carry out diagnostic and therapeutic methods for pain diseases. The development of pain medicine in China can be traced back to the 1950s, when acupuncture paralysis (needle numbing) appeared in China to treat a variety of chronic intractable pain. 1989 saw the establishment of the Chinese branch of the International Academy of Pain, followed in 1992 by the establishment of the Pain Society of the Chinese Medical Association. With the rise of domestic pain medicine, the opening of major hospitals pain department, on July 16, 2007, the Ministry of Health issued a “medical institutions to increase the number of diagnosis and treatment subjects list” in the “pain” diagnosis and treatment projects notice document, and determine the “pain” as a The Ministry of Health issued a notice on the addition of “pain” diagnosis and treatment program to the list of medical institutions, and determined that “pain” as a clinical first-class diagnosis and treatment subjects, the provisions of the second level of hospitals to take the lead in the development of pain diagnosis and treatment services. Second, what is pain: with the actual or potential tissue damage related to the unpleasant feeling and emotional experience. Is the most primitive, the most common human suffering, is listed as breathing, pulse, blood pressure, body temperature after the fifth vital signs. Third, the obstacles to the development of pain medicine by the influence of traditional concepts and the limitations of knowledge, most patients, including some medical personnel do not understand the true meaning of pain medicine, understanding the field of pain medicine, there are still some misunderstandings: Misunderstanding of a: pain treatment is only a symptomatic treatment, do not solve the fundamental problem, that is, the so-called “treating the symptoms but not the root cause”. This idea is obviously wrong, the traditional means of treatment is analgesic drugs plus massage, traction, heat therapy, acupuncture, etc., only to solve the “pain” problem, now the pain department more minimally invasive interventional techniques, the problematic nerve nutrition, decompression, conditioning, stimulation, and even destruction and other therapies, so as to achieve the anti-inflammatory, analgesic, blocking nociception, improving nerve function. In order to achieve anti-inflammatory, analgesic, blocking pain conduction, improve the purpose of nerve function, play a role in treating both symptoms and root causes of pain diseases. And the process of certain diseases itself is a vicious pathological cycle caused by pain, lifting the pain is the treatment of disease, such as shingles. Myth 2: pain doctors will only prescribe painkillers, playing nerve block Internal medicine treatment is based on medication, surgical treatment is based on surgical treatment, rehabilitation is based on physical therapy, anesthesiology is mainly to solve the acute pain in the perioperative period, while the pain department needs professional theoretical knowledge and operational skills, first of all, for the clinical departments related to the treatment of all kinds of pain is not good, to make a clear diagnosis, and then to take medication or non-drug Means, non-invasive, minimally invasive methods of treatment, for various types of herniated discs, trigeminal neuralgia and other chronic pain patients, the pain department has its own unique minimally invasive technology, without incision, minimally invasive surgery can be carried out only under local anesthesia, the patient’s trauma is small, low cost. Misconception 3: The patient is in a hurry to seek medical advice, frequent search for medicine, and mislead the condition. For acute, caused by the primary disease pain, we should consult the appropriate departments, such as angina pectoris, we consult the cardiology, sudden acute abdominal diagnosis of general surgery, etc., and chronic intractable pain, including pain did not find out the cause of the disease or find out the cause of the disease can not be rooted out at present need to go to the Department of Pain to treat, such as do not get timely and effective treatment, it will become a complex local pain syndrome or central pain, more severe pain, more difficult to treat, and the pain will be more severe, and more difficult to treat. The pain is more intense and more difficult to treat. Myth 4: after pain treatment is not what feel no more The human body’s nerves are divided into sensory, motor, vegetative nerves, etc., the treatment of pain, just selective blocking of sensory nerve conduction or destruction of nociceptive fibers, and does not affect other nerves. Fourth, the pain department diagnosis and treatment items: 1, acute pain: soft tissue and joints acute injury pain, post-surgical pain, obstetric pain, acute herpes zoster pain, gout, etc.; 2, chronic pain: soft tissue and joints strained or degenerative pain, intervertebral disc pain, neurogenic pain, etc.; 3, intractable pain: trigeminal neuralgia, post-herpetic neuralgia, herniated disc, intractable headache, etc.; 4, Cancer pain: advanced tumor pain, tumor metastatic pain, etc.; 5, special pain category: thrombophlebitis, intractable angina, idiopathic chest and abdominal pain, etc.; 6, related disciplines of disease: early retinal vascular embolism, sudden deafness, vascular spasmodic disorders, facial spasms, allergic rhinitis, intractable ergonomics, peripheral vascular disease, insomnia and so on. Fifth, the function of pain physicians: 1, to promote the basic study of pain medicine 2, carefully examine the patient, make a correct diagnosis 3, the neurophysiology of pain and psychology have a depth of knowledge 4, with love and patience to suffer pain patients to be careful care 5, the radiological examination data, general medical examination, electrophysiological examination, psychological testing data have the ability to identify and read the data 6, and the treatment of pain related to the depth of the clinical pharmacology of drugs 6, the clinical pharmacology of drugs related to pain treatment have in-depth understanding of the rational use of analgesic drugs 7, will be able to implement a variety of new pain treatment techniques six, pain treatment methods: 1, nerve block: block pain and other injurious stimuli to the central conduction, thereby breaking the vicious pathological cycle, both symptomatic treatment, but also the cause of the treatment of 2, physical therapy: including direct current therapy, drug ion implantation therapy, red (violet) external therapy, ultrasound therapy, etc. 3, electrotherapy, electrodynamic therapy, physical therapy and other treatment methods, physical therapy and other treatment methods. 3, electrical stimulation therapy: pulse current stimulation can cause peripheral nerve fiber excitation, impulse conduction to the central system, so that the release of encephalphalogens and endorphins, causing analgesic effect. 4.Radiofrequency therapy: it can selectively destroy the nociceptive fibers and retain the sense of touch. 5.Laser therapy: low-energy lasers such as helium-neon lasers are mainly used in physical therapy, with anti-inflammatory, analgesic, and promote tissue regeneration, which can treat local inflammation, skin ulcers, facial spasm and so on, and carbon dioxide laser diffusion irradiation for the treatment of sprains and contusions, arthritis, neuralgia, and laryngitis, etc. 6.Psychological therapy: the use of the principles and techniques of psychology. Psychotherapy: Using psychological principles and skills, through language, expression, attitude, posture, behavior and the role of the surrounding environment, to influence and change the patient’s understanding, emotions and behavior, so as to achieve the improvement of their psychological state, behavior and physical symptoms. 7. Spinal endoscopic surgical treatment: For all types of lumbar disc herniation, the spinal endoscopic system can be used to directly remove the nucleus pulposus that oppresses the nerve root, so as to lift the compression of the nerve root. There are also various minimally invasive treatments such as collagenase disc dissolution, ozone injection, plasma radiofrequency ablation, and anhydrous alcohol nerve destruction. Seven, the prospect of pain medicine Pain medicine is a comprehensive medical specialty, with a high degree of cross-specialty, a wide range of medical treatment, covering a large population, the patient’s condition is complex, the treatment mode is effective and minimally invasive, the clinical outlook is broad. Over the years, the development of pain medicine in China is not balanced, some well-known hospitals have not set up a pain department, some hospitals carry out pain department, or outpatient clinics, mostly for anesthesiologists part-time, the cultivation of pain medicine specialists has a lot of space, but with the improvement of people’s awareness, the development of social needs, pain medicine will certainly occupy a pivotal position.
