Infiltrate after injection: causes and complications
Sometimes after intramuscular injections in their placea seal may form. In medicine, it is called an infiltrate, and it is characterized by the accumulation of cellular elements containing impurities of lymph and blood in the tissues of the body. In most cases, an inflammatory infiltrate occurs after the injection, mainly consisting of leukocytes (then called purulent) and red blood cells (then called hemorrhagic).
Infiltrate after the injection can appear on manyreasons. The most common of these are the wrong choice of an injection site or permanent injections in one place, the injection of a short or blunt needle. To avoid the formation of infiltration after the injection, it is necessary to follow certain recommendations. So, it is necessary to strictly observe the aseptic rules to prevent the infiltration of infectious agents into the wound, because this can be fraught with complications, for example an abscess. You should pay attention to the length of the needle, as already mentioned, it should not be short. Infiltration after the injection can occur if the injected substance does not resolve, especially for oil solutions. In this case, a dense cone appears at the injection site. If, in addition, a bruise is also noticeable, then under the skin of a blood vessel that has been damaged by a needle, some amount of blood has leaked out.
If the accumulation of cellular elements in placeinjection in the general state of the person does not cause changes, and suppuration does not arise, nothing should be done. Usually within 2 weeks the infiltrate appeared after the injection itself disappears. Treatment in most cases is not required. Do not massage the affected area, trying to ensure that the seal is absorbed. This is fraught with the development of complications. The need for therapy arises only in the case of an infectious process that causes an abscess. In this case, antibiotic therapy is prescribed, and if necessary, surgical intervention is also performed.
Complications
As already noted, the only possiblethe complication of the appearance of a seal at the injection site is the development of an abscess - an inflammatory condition, in which tissue melts and the formation of a cavity with purulent contents takes place. Signs that the abscess begins, can be the redness of the affected area, the soreness of the compaction, the high temperature at the site of the infiltration. Abscess should be treated necessarily, and it should be done only by a doctor. Self-treatment is fraught with aggravation of the condition.
