If the scar is too large during injection, it should be injected in points with a distance of about 1cm. The infiltration range of each acupoint can be divided into 0.5~ 1cm, and it is best to enter the needle vertically from the scar surface. The level of injection should be strictly controlled, and it can only be injected into keloid entities through liquid medicine, and it is strictly forbidden to inject into subcutaneous or surrounding normal tissues. When the liquid medicine begins to penetrate into the surrounding tissues, stop the injection and pull out the needle.
If the injection level is too shallow, the scar surface is easy to bubble and rupture under the action of high water pressure, resulting in new wounds and infections. When pulling out the needle, the syringe should be decompressed first, otherwise it is easy to spray the liquid medicine out of the body. If obvious side effects or ineffectiveness are found after 2~3 injections, the drug should be stopped or the drug variety should be changed in time.
If the injection contains high-efficiency corticosteroids, the principle of gradual reduction should be followed when the injection treatment is stopped: once a week is gradually changed to once every 2 weeks, 3 weeks and 4 weeks, and the injection dose is gradually reduced. This can effectively prevent the rebound caused by sudden drug withdrawal and reduce the recurrence rate. In addition, after drug withdrawal, it can be combined with external ointment, silica gel sticking film or local compression, isotope application, audio-frequency electrotherapy and other comprehensive treatments to consolidate the curative effect.
The above introduction is the knowledge of injection scar removal method, hoping to help you.
