Why do intraarticular injections?
Injections of drugsintra-articular cavity for the first time began to do in the seventies of the twentieth century. We can say that this was a breakthrough in the treatment of patients with degenerative-dystrophic lesions and inflammation in the hip, knee, shoulder joints. Glucocorticosteroids administered to patients suffering from bursitis. arthritis, Periarthritis, synovitis, inflammation afterinjuries to suppress the mechanisms that trigger the inflammatory pathology. But hyaluronic acid preparations in the joint cavity shown in osteoarthritis. In this disease, a destructive disorders observed generation (synthesis) synovial fluid - a kind of natural lubricating material filling the joint cavity. Synovial fluid provides nourishment and sliding joint, thus reducing its friction and wear. Hyaluronic acid is an important component of synovial fluid, it gives her strength, cushioning properties. Some experts compare the effect of introducing into the joint cavity of sodium hyaluronate with implantation of an artificial joint. Hyaluronic acid gets into the joint cavity, trying to make up for the missing part of the synovial fluid. Penetrating directly into cells, "pulls" for a water, thereby facilitating recovery at the same time when the articular cartilage damage. If time to make intra-articular injections of hyaluronic acid, it is possible to avoid replacing the diseased joint with an artificial or defer this operation permanently. Because hyaluronic acid can fulfill the role of the prosthesis, allowing the patient to maintain the joint gradually restore function performed by them previously.
The drug in the syringe is sterile, for its introduction requires a sterile needle size from 18 to 20. After the introduction and the needle and syringe disposal.
The drug should be administered intra-articular (ieIt is in the synovial space of the affected joint disease). A single dose is usually 2 ml, injection is carried out once a week. To achieve a lasting effect, it is necessary to make such 4 or 5 injections, the interval between which is 7 days. If osteoarthritis of moderate or moderately severe, the therapeutic effect lasts 6 months or more.
Available in more drug called "FermatronPlus ", two of which contained no ml 20 mg (as Fermatrone) and 30 mg sodium hyaluronate. This preparation for the course requires 3 capsules, that is to be held 3 intra-articular injections.
Intra-articular injections should exerciseOnly a doctor with a special qualification, the confirmed certificate. This treatment is given only after a full examination of the patient orthopedics, traumatology, rheumatology.
The procedure is performed in a clean dressing according to all the rules of asepsis to avoid getting an infection in the joint cavity.
The drug must be at room temperature.
If the exudate is present in the cavity, the physician removes the first through the needle.
When the doctor saw that the needle is inglenoid cavity, it begins to introduce medication. The procedure is now trying to do ultrasound or fluoroscopic control, allowing to accurately place the needle in the right place.
2 ml - a dose for large joints. The small joints of the drug is administered less, but the remaining solution can not be used a second time.
After the procedure long limb should be at rest (several hours). In the following days, it should not be overloaded.
About contraindications and side effects
Fermatronom treatment can not be carried out at:
- acute synovitis (otherwise therapeutic effect is greatly reduced);
- presence in the introduction of skin diseases, abrasions, infected wounds;
- severe inflammation of the joint;
- Hypersensitivity to the components of the tool.
Babies Fermatron not introduced. Data showing that the drug is safe during pregnancy and breastfeeding is not available, therefore the use of only solved by a specialist.
Sometimes when administered Fermatrona appear short side effects:
- redness, swelling at the injection zone;
- increased allocation of exudate;
- moderate pain;
- allergic reaction (very rare);
- inflammation in the joint (extremely rare).
The drug is expensive. But patients who have passed the course of intra-articular treatment report that their health improved after Fermatrona gradually decrease pain, restores mobility in the joint. Fermatron acting as an analogue of human synovial fluid breaks the dominant element, which is the cause and progression of osteoarthritis. In addition, in the body triggers the synthesis of endogenous (own) hyaluronan, gradually properties synovial fluid recovered.
