The term “closure” is widely used in this country, is it the same as nerve block? Is that the correct medical term? We often encounter arguments among doctors about this. Neural blockade” or “Nerve block” is a term that has been used around the world for nearly a century and is still in use today, referring to the use of drugs and other means to block the conduction of nerve impulses. In any case, it should not be translated as “closed” or “nerve block”. However, there are still many doctors who call “nerve block” or “injection therapy” as “closure”. The term “closure” was created in China in the 1950s, and it is understandable that it was difficult to understand the correct terminology abroad because of the difficulty in exchanging academic information with foreign countries. Over time, it was called a habit. But nowadays, it is better to advocate the use of correct international medical terminology. It’s like calling “abdominal pain” a “stomach ache”; although there is nothing wrong with it and everyone can understand it, it just comes out of a doctor’s mouth and makes people feel irregular. Many doctors who are not specialized in pain management, and even some nursing staff, due to lack of systematic knowledge and training, are enthusiastic about injecting multiple drugs at pain points, acupuncture points or nerve endings to relieve pain, which they call themselves “closed therapy”. Some add small amounts of local anesthetic drugs to the injection solution, while others do not. Some doctors inject a wide variety of drugs locally, such as antibiotics, animal blood products, animal organ products, herbal preparations, anti-immune preparations, and anti-tumor drugs into the injection. Although this type of treatment can sometimes relieve the pain of some patients, many instances of complications and medical disputes have occurred. There are also some social loafers, to make money for the purpose of “a needle away”, everywhere “closed”, so that the word “closed” adds a bad color. This “closed therapy” name is widely circulated, so that some medical personnel and some patients on the regular “nerve block” also have misunderstanding, and even have fear. In my opinion, it is not appropriate for regular doctors to use the informal term “closed”. Moreover, the term “closure” is not found in the English, Russian, or Japanese pain literature. In pain management, it is better to call it nerve block or injection therapy, both of which are commonly used worldwide and are scientific and standardized. One of the most common treatments in pain medicine, “nerve block” therapy, is worth mentioning. The local anesthetic blocks the neurotransmission of injurious stimuli, leaving the nerve in a semi-dormant state, thus activating the active self-adjustment and self-repair of the internal nervous system and its innervation areas. The treatment is minimally invasive and uses a small amount of drugs, allowing patients to get maximum results with minimal cost.
