In the outpatient work, when patients are told that the condition requires a variety of block treatment, patients usually ask a question: “doctor, I am this needle is not closed ah, is closed can not play ah. In the vast majority of patients’ perception: 1, “closed” seems to be where the pain hit where the treatment of the symptoms but not the root cause, the anesthetic force past the pain. 2, “closed” in the use of drugs containing hormones, hormones are bad, can be “addictive”, can osteoporosis, can be fat. 3, “closed” very painful. Because the closure has so many shortcomings people do not accept the “closed” treatment, but also “closed” treatment into the wrong area, often many people fear “closed” refused to treat, delaying Treatment time is delayed. Therefore, some doctors when asked this question often answer “not closed, it is nerve block”. I don’t know what “closure” is in the eyes of the general public, but from what I have seen, painful point blocks, tennis elbow, and synovial blocks are probably considered “closure” by them. The English word for closure is “block”, which is now known as block therapy. However, people do not need to talk about “block” and refuse to “close” because: 1, the treatment through the anesthetic effect of anesthetics can block the vicious cycle of pain, let the lesion get rest, improve blood circulation, eliminate inflammation and edema. 2.The hormones contained in it have the effect of eliminating inflammation and edema. After the action time of anesthetic drugs, the medium and long-acting hormones still play a role, such as tennis elbow and other diseases, which can eliminate the sterile inflammation at the external epicondyle of the humerus and fundamentally solve the pain of patients. 3. Short-term local use of hormones has little effect on normal people, but hormones have the effect of raising blood sugar and blood pressure. Therefore, within the effectiveness of hormones, diabetic patients need to pay attention to monitoring changes in blood sugar and adjusting the use of hypoglycemic drugs according to blood sugar results, and hypertensive patients pay attention to changes in blood pressure and consult a specialist if necessary. Patients with osteoporosis should pay attention to calcium supplementation. 4, in some block treatment, patients do produce a short period of more painful soreness, especially in the serious parts of the lesion, most of them can be tolerated, inform patients of the serious soreness of the site of injection therapy is more effective, most patients can accept. I hope you have a preliminary understanding of the “closed” treatment, when the need for treatment do not say no too soon.
