What Is Nerve Block Therapy?

Nerve block technique is the most commonly used magic weapon by pain therapists. For many shoulder, neck, waist, or limb parts of the tendon sheath, synovial sac, tendonitis, sacroiliac arthritis, piriformis syndrome, tennis elbow, carpal tunnel syndrome has a good effect. Heritage after herpes zoster pain, trigeminal neuralgia, sciatica, phantom limb pain, burning pain, such as intractable pain neurons, application specific nerve block technique and neural methods of frequency modulation (hot) electric stimulation, by blocking pain pathway, improve nutritional status, adjust nerve conduction function, obtained the satisfactory therapeutic effect. In the actual clinical treatment, some diseases with drugs and other conservative treatment is ineffective, but not suitable or can not tolerate surgery. The nerve block method can obtain the effect that the drug treatment cannot obtain, for the patient, the injury is less, the effect is faster than the operation treatment, and the tolerance. In other words, nerve block therapy is a kind of treatment between conservative medical treatment and surgical treatment. Someone called the nerve block technique closed therapy, it is wrong, "closed" is a word to generate understanding of pain, treatment less '50 s, at the time it is difficult to communicate with foreign academic information is difficult to know the correct term abroad, in translation when the Russian was wrong, is understandable. Who knows a long mistake has become a habit, and now many doctors still think that the treatment of pain doctors is block therapy. The word "block" is very popular in China. Is it the same as nerve block? Which one is the correct medical term? The term Nerve block has been used all over the world for nearly a century and is still used today. Nerve block refers to a treatment in which the conduction of nerve impulses is blocked by means of drugs, etc. It should not be translated as "injection blocking" or "blocking therapy". At present, some non-pain specialist doctors and even some nursing staff, due to lack of systematic knowledge and training, are keen to inject multiple drugs into the pain point, acupoint or nerve terminal to relieve pain. They call themselves "block therapy". Some added a small amount of local anesthetic in the injection, some did not add. Some are used for local injection of a wide variety of drugs, adding antibiotics, animal blood products, animal organ products, traditional Chinese medicine preparations, anti-immune preparations, anti-tumor drugs and so on. Although this kind of treatment can relieve the pain of some patients sometimes, there are many cases of complications and medical disputes. There are also some idle people in society who, for the purpose of making money, "go all over the world with one stitch" and "close off" everywhere, which adds a bad color to the word "close off". The name of this "closed therapy" is very widespread, so that some medical staff and some patients on the normal "nerve block" also misunderstanding, and even fear psychology. Formal doctors should not use the informal word "closed". Moreover, there is no source of the word "block" in the English, Russian or Japanese pain literature. In pain management, it is better to call it nerve block therapy. This term is universal, scientific and normative. The effect of nerve block therapy is based on at least the following three aspects in medicine: one is to prevent the sympathetic nerve, make the vasodilatation, edema reduction, relief of pain and relief of the sympathetic nervous state associated with the disease; The second is to block sensory nerve, block the conduction of pain and inhibit the symptoms induced by sensory nerve stimulation; The third is to block the motor nerve, so that muscle relaxation or temporary brake, so that the pain site to get "rest". Nerve block therapy is a treatment method that uses local anesthetic drugs, such as lidocaine or bupivacaine, combined with steroids and vitamins injected into the site of nerve pain to eliminate inflammation and relieve pain. But many patients do not know much about nerve block therapy, often not easy to accept, think that the injected drugs contain hormones, adverse to the human body, will cause osteoporosis, and even some orthopedic surgeons will oppose. In fact, with nerve block therapy, there is far less need to be so nervous. If we understand its role, indications and contraindications, we will understand and accept it. In order to achieve the expected effect of nerve block therapy, three important steps must be passed, that is, correct diagnosis, effective drug composition and exquisite injection skills. The local anesthetic drugs such as lidocaine or bupivacaine in nerve block therapy are the anesthetics which have a friendly to the nervous system, it can block the vicious cycle of pain, make the nervous system get rest and adjustment, can protect the nervous system. It also has a strong analgesic effect, can block the local lesions send out pain signals. Most soft tissue pain is caused by local aseptic inflammation and soft tissue congestion and edema to stimulate the nervous system. Lidocaine and other anesthetic drugs combined with steroid drugs (hormones) can change the local blood circulation, reduce inflammatory exudation, promote the discharge of local metabolites, thereby eliminating local inflammatory edema, promote inflammation absorption, and alleviate muscle spasm. For CHRONIC lesions with ADHESIONS, DRUGS FOR activating BLOOD circulation and removing BLOOD stasis, regulating QI and relieving pain are added to eliminate adhesions, soften and firm and disperse knots, remove blood stasis and regenerate, improve tissue metabolism and relieve pain. Cancer patients, need to add hormone treatment, especially cancer cells rapidly spread, metastasis to the spine caused by lower limb pain, numbness and so on. Some people worry that the hormone drugs used will cause side effects on the human body, in fact, because of the small amount of nerve block treatment, used locally, and not long-term use, will not have any effect on the human body. Therefore, nerve block therapy has the advantages of direct administration and rapid curative effect. Some diseases can be cured after treatment. The treatment should be clear diagnosis, aseptic operation, accurate location, appropriate medication and so on. Once the nerve block therapy is selected, the treatment should be adhered to to complete the course of treatment, so as not to stop halfway and achieve the due effect. If the nerve block therapy is properly operated, there is basically no danger, the patient has no special discomfort, the amount of steroid drugs used locally is small, the absorption is slow, the maintenance time is long, and there is no obvious side effect on the body. The use of hormones in nerve block to enhance the therapeutic effect has a history of nearly 60 years, of course, the use of hormones should follow the principles of caution and responsibility, rational application, as needed, short-term appropriate amount of drugs, to prevent abuse
