4hw.com.cn: it is often seen in the news that some athletes choose to play a "closed" shot in order to keep the competition state and performance from being affected by pain. While lamenting the athletes' spirit of struggle, we will have a question: what is the sanctity of the 'closure' that can help athletes to eliminate pain and play games?
The so-called blocking treatment refers to the injection of specific drugs into muscles, nerves and skeletal structures (bursa, joints and tendons) to reduce pain and improve function. This kind of treatment can inject the medicine directly to the pathological area, and play the largest role in the pathological area.
The so-called closed needle is to inject a certain concentration and volume of prednisolone injection (dexamethasone, betamethasone, etc.) and procaine hydrochloride (or their similar drugs) into the lesion area. Can play the role of anti-inflammatory pain relief, spasm and so on.
The drug nature of the closed needle injection determines that the therapeutic effect of the closed needle is limited. Generally, the main drug components of the closed needle are anesthetics and hormones,
There are two main therapeutic effects of closed needle
(1) The temporary anesthetic analgesic effect of procaine hydrochloride or its equivalent.
(2) The prednisolone used in the closed needle belongs to hormone drugs. The principle is the anti-inflammatory effect of hormone, the improvement of capillary permeability, the inhibition of inflammatory response, the reduction of the role of pathogenic factors on the body damage, to alleviate the pain caused by various chronic soft tissue damage.
Some athletes suffer from repeated attacks and long-lasting injuries due to some reasons, which affect their training and competitive performance. At this time, for the consideration of competition, they will put a needle in the face of playing. So, can only athletes play the closed needle?
In fact, block therapy is a very common method in orthopedic diseases, not only for athletes, but also for the general population if they meet the indications of block therapy.
General adult acute and chronic soft tissue strain, joint pain, muscle attachment point pain, neuralgia, periostitis, fasciitis, radiculitis and other diseases of the movement system can be treated with blocking therapy. Closed needle is mainly used to Treat Periarthritis of shoulder, tennis elbow, tenosynovitis, lumbar muscle strain, and various bursitis and other diseases.
Because some patients don't know much about this treatment method, they are afraid of side effects of hormone drugs in the closed needle and refuse the closed therapy. Clinically, some patients will have resistance when they hear that they need to be injected with closed needle. They think that this kind of treatment can only temporarily relieve symptoms, and can not fundamentally solve the problem. Others are worried that they will become addicted after injection. Is the problem really so serious?
There are some side effects in the use of hormone drugs, such as cardiogenic obesity, body shape change, hairy skin, and even make female patients grow beard, which leads to the decline of anti infection ability of human body, slow wound healing speed, but also can aggravate gastrointestinal ulcer, induce hypertension, psychosis, osteoporosis, aseptic necrosis of femoral head, etc.
Undeniably, there are some side effects of hormone, but these side effects are long-term, large doses of repeated application. As for injection, the hormone dosage is very small, absorption is slow, and the interval is long. So don't worry too much.
There are many patients worried that the injection will occur, which is actually a mistake. The so-called hormone dependence mainly refers to the fact that the symptoms of some diseases are completely controlled or partially relieved after hormone treatment, but the hormone is suddenly stopped or the dosage is rapidly reduced, and the disease relapses or worsens immediately. But this situation only exists in the long-term, large dose, repeated use of hormone treatment. A closed course of treatment is generally only 3-4 times according to the condition, with 7-10 days interval each time, and the dosage of each hormone is very small, so there is no need to worry about the production of hormone dependence.
Finally, I'd like to remind you of some precautions for block therapy
1. Sufficient treatment course
Many patients mistakenly think that the blocking treatment can only temporarily relieve pain, and they will not continue after one injection. However, once the sealing therapy is selected, the treatment should be insisted on and the treatment course should be completed, so as not to stop halfway and achieve the desired effect. Although blocking therapy can not remove the cause of disease fundamentally, it can reduce or even eliminate symptoms and prevent complications. Many neck, shoulder, waist and leg pain after one or several closed treatment, the symptoms completely disappeared and no recurrence. Therefore, it can not be absolutely considered that the root cause of the disease can not be removed by blocking treatment.
2. Symptomatic selection
The indications of blocking therapy were soft tissue injury and aseptic inflammation, and local pain points were obvious. It is not suitable for those patients with diffuse pain. For the sake of safety, hypertension, diabetes, gastric and duodenal ulcer, active tuberculosis, osteoporosis, acute suppurative arthritis, psychosis and other patients and pregnant women should be used with caution.
3. Location
If we hit the right place, the curative effect will be immediate. Of course, the local pain of some patients may be slightly aggravated within 1-2 days after injection, but it will disappear soon.
4. Correct operation: in order to prevent infection, the closed injection should be carried out in a regular hospital, and the dosage should be strictly controlled according to the condition. Keep skin clean within 3 days after sealing to prevent pollution. Some patients in the health conditions of small clinics do not meet the standards of closed needle, there are joint infection suppurative, tissue necrosis and other problems, so that the pain is aggravated, the gain is not worth the loss.
