However, as soon as some patients heard of "closing the needle", they frowned and waved their hands again and again, refusing to accept it. The reason is that they heard that "blocking the needle" can only temporarily relieve the symptoms of the disease, but can not fundamentally cure the disease. In addition, I'm afraid that after I've had a "closed needle", I'll keep playing from now on, but I can't stop. Besides, I'm worried about the side effects.
These patients are not uncommon. Are their concerns justified? We might as well start from the beginning.
The so-called blocking therapy is usually to inject a certain concentration and quantity of prednisolone injection and procaine hydrochloride into the lesion area. Muscles, joints, fascia, tendons and even spinal canal can be injected in a closed way. Prednisolone, dexamethasone, betamethasone and other similar drugs are hormones.
Hormone is an active substance produced by endocrine organs of human body, which can produce physiological effects. There are many kinds of hormones, such as sex hormones, thyroxine and insulin. However, there seems to be an unwritten agreement and tacit understanding between doctors. Unless otherwise specified, hormone refers to pine substances secreted by adrenal cortex (also known as cortical hormone). Its artificial imitation products have similar functions, so it is called. Their discovery and clinical application have a history of more than half a century. Adrenal cortical hormone is widely used in medicine. They are the bane of all kinds of allergies; It also has immunosuppressive effect and can be used for diseases caused by abnormal immune response. They are favored by doctors in clinical medicine.
Orthopedics doctors attach importance to their treatment of various pain diseases mentioned above, mainly by using their anti-inflammatory effects. They can improve capillary permeability, inhibit inflammatory reaction and reduce the damage of pathogenic factors to the body. At the same time, procaine (also known as novocaine) is a local anesthetic used for local anesthesia during tooth extraction and minor surgery. It can relieve pain and enhance the effect. Sometimes its analog lidocaine is also used, and the effect is similar.
Must I always have a "closed needle" after an injection? We know that these hormones are not addictive. But long-term application will produce habituation and dependence. Habitual is to use hormones repeatedly for a long time to relieve symptoms and form conditioned reflex. Feel uncomfortable or scared after stopping taking the medicine. At this point, after giving a small amount of hormones, the symptoms quickly disappeared. Dependence refers to the so-called "rebound" phenomenon that the symptoms of some diseases are completely controlled or partially relieved after hormone treatment, and when the hormone is suddenly stopped or the dose is quickly reduced, the original diseases relapse or worsen. Both of these conditions may occur after long-term, high-dose and repeated use of hormones. Orthopedics uses blocking therapy, usually one or more times according to the condition. The interval between each time is 7 ~ 10 day, and generally it does not exceed 3 ~ 4 times continuously. If it is necessary to continue the injection, the interval is very long and the dose used is very small. Therefore, since the implementation of this treatment method, the phenomenon of "always hitting" has rarely appeared.
The obvious pain during injection is the main reason why patients are unwilling to accept it; After 1 ~ 2 days, the local pain may be slightly aggravated, which is related to drug stimulation and local pressure increase, and will soon disappear.
Corticosteroids, like all other drugs, have side effects. Such as centripetal obesity, body shape change, hairy skin, and even female patients with beards; It will also lead to the decline of human anti-infection ability and slow down the wound healing speed; It can also aggravate gastrointestinal ulcer and induce hypertension, psychosis, osteoporosis and aseptic necrosis of femoral head. However, this phenomenon will only appear after long-term repeated use of large doses. Generally, short-term local blocking therapy will not cause these reactions. For the sake of safety, doctors are always cautious about patients with severe hypertension, gastrointestinal ulcers, diabetes, mental illness and so on. In order to prevent infection, closed injection should be carried out in medical units. Wash the skin with soap and water before sealing and disinfect it strictly. Observe 15 minutes after injection to prevent allergic reactions. Pay attention to keep skin clean within 3 days after sealing to prevent pollution.
Of course, like other drugs, hormones are not the legendary "panacea". In some cases, the effect may be poor. If necessary, it can be combined with traction, massage, physical therapy, wearing waist circumference, internal and external medication and other methods. Turn to surgery if necessary.
By the way, some medical units or medical practitioners with improper medical behavior add some other drugs, such as vitamin B injection and angelica injection, to the general "closed needle", or use unusual synonyms to call themselves "secret recipe", "specific medicine", "imported medicine" and "patent", which will increase the price by ten times or even dozens of times and make high profits. Because they didn't clearly tell the patients that the injection was "closed" in nature, they induced the patients to go there for treatment again and again, and as a result, there was an undue reaction, which is worth noting.
