Causes of skin redness and blackening and treatment of necrosis
Erythema and blisters are the initial reactions of bedsores. If the pressure is still not in contact at this time, or the caregiver does not strengthen the protection, then the erythema may develop dark spots or superficial ulcers.
The main cause of skin darkening is due to the necrosis of subcutaneous tissue, which causes the skin to become an isolated tissue, continuously losing nutrients and completely necrosis, becoming a “black dead skin” or “black spot”, and a large amount of necrotic pus and tissue may be wrapped under the black skin , It is relatively tricky to deal with.
There are two development directions for the black skin in the later stage. One is natural ulceration, and the underlying ulcerated wound is exposed; second, the necrotic pus tissue under the black skin continues to penetrate, implicating the secondary necrosis of normal tissues, forming a deep cavity wound.
The first situation is well understood. Because the black skin has been necrotic, its toughness and tolerance will also be weakened. It will naturally break under friction or squeezing, and the underlying wound will be exposed.
The second case is due to better skin protection, causing necrotic black skin to continue to cover the wound surface, while the subcutaneous tissue continues to necrosis due to repeated pressure, the resulting pus tissue cannot be discharged from the body, and it will continue to penetrate around, implicating normal tissues Necrosis also occurs, forming a subcutaneous cavity wound, and the lateral depth can develop to 3–6 cm from the wound edge. We can use cuts cream for smearing treatment to coordinate skin regeneration and repair.
Necrotic black skin treatment method:
The longer the appearance of necrotic black skin, the worse the evolution of the subcutaneous cavity. Therefore, it is necessary to take preventive measures as soon as possible. Use tweezers, small scissors and other tools to cut open the necrotic black skin to completely expose the decayed flesh underneath. Manually clean up the wound. It becomes clean, and then apply cuts cream according to the specific depth to restore the muscles.
After debridement of relatively shallow wounds, apply cuts cream directly, and then bandage with gauze. For wounds with a depth of more than 1cm, or wounds with subcutaneous cavities, you need to cut gauze to make gauze strips to fill the inside of the wound so that the cuts cream is in contact with the inner wall of the wound. Full contact effect to maintain long-term antibacterial care and muscle growth repair.
Bed sores are chronic wounds, and the recovery period is longer than that of ordinary wounds. Therefore, special attention should be paid to preventive care. In addition to turning over frequently, check the pressured skin regularly, and apply cut cream as soon as possible to penetrate and repair bedsores and erythema.
Here is a method for preventing bedsores! To judge whether the skin is completely crushed, there is a very simple test method-Shiatsu test! Press the pressured part of the skin with your finger for more than ten seconds, and then release it. If the skin changes from red to white, and then slowly returns to normal red, it indicates that the blood is flowing smoothly; on the contrary, if the blood becomes white, it does not recover. Normal blood red indicates that the skin has been crushed.
