—- written in 2014 World Analgesia Day, China Analgesia Week Zheng Baosen, Director of the Pain Branch of the Tianjin Medical Association, Tianjin First Central Hospital, Professor Zheng Baosen, Department of Pain, Tianjin First Central Hospital According to the initiative of the World Pain Society, the third Sunday of October is celebrated as “World Analgesia Day”, and the Chinese Pain Society The third Sunday of October is designated as “World Analgesia Day” according to the initiative of the World Pain Society, and the week is designated as “China Analgesia Week” by the Chinese Pain Society. Every year, during World Analgesia Day and China Analgesia Week, the Pain Society of the Chinese Medical Association (CMA) actively organizes pain specialists across the country to respond to this call and promote to pain patients nationwide how medical experts can relieve the pain “demons” that have been haunting pain patients for thousands of years. The World Pain Society has proposed this year’s theme of conquering “neuropathic pain”, so what is “neuropathic pain”? Currently, pain is defined as neuropathic pain when it is caused by damage or disease of the somatosensory system and lasts for more than one month. According to the research data released by the World Health Organization, the incidence of neuropathic pain in the general population is as high as 8%. According to this projection, there are more than 90 million patients suffering from neuropathic pain in China, of which “trigeminal neuralgia” and “postherpetic neuralgia” are the two most common and difficult to conquer. More than a decade after the July 20, 2007 notice of the former State Ministry of Health on the addition of “pain department” to the “List of Medical Institutions”, pain physicians were born to challenge the “demons” of pain. Pain doctors were born to challenge the “demons” of pain. They have not given in to the “demons” and have been conquering them one by one by using their long-standing expertise in pain treatment. In the face of “trigeminal neuralgia” and “postherpetic neuralgia”, which represent the first neuropathic pain, the research has made remarkable progress in recent years. Pain physicians are not only “artists” in controlling most of the pain patients with various drugs, but also in performing their specialized minimally invasive interventional techniques to cleverly block the pain nerve conduction pathways in a small number of patients with intractable pain without damaging normal nerve function. How do pain physicians achieve this technique? As we all know, CT is an advanced instrument that specializes in accurate diagnosis of diseases, and the pain physician, under the guidance of CT, can precisely place a puncture needle into the “nest” where the lesion is causing the nerve pain and inject a tiny amount of drug (0.5 ml) around the nerve cells that are specifically responsible for the pain transmission. After a few days, the injected micro-drug can slowly infiltrate into the diseased nerve cells and “poison” the nest of the pain “demon”, a phenomenon called “apoptosis” in medical science. phenomenon. After more than ten years and thousands of cases of clinical research, this technology not only can safely and effectively reduce the “trigeminal neuralgia” and “post-herpetic neuralgia”, these two “demons”, but also has no effect on the function of normal cells. The function of normal cells is intact. This technology is one of the components of the “2013 National Science and Technology Support Program Project, Multi-center Research Program for Demonstration of Neuropathic Pain Intervention” conducted by the Pain Department of Tianjin First Central Hospital. The need to behead the “demon” of pain is not only the demand of many pain patients, but also a challenge for pain doctors.
