For the prevention of pressure sores, the following points should be noted: 1. Avoid prolonged pressure on local tissues. 2. Avoid pulling and pulling patients when moving them. 3. Keep patients’ bed sheets dry, neat and free of scales. 4. Keep patients’ skin clean and dry. 5. Turn and pat patients’ backs regularly and massage the areas under pressure. 6. Ensure patients’ nutritional intake. For the care of pressure sores, preventive measures should be strengthened, and patients should be given aseptic dressing changes and bandages according to the degree of pressure sores. Infected pressure sores should be treated with anti-infective drugs, and particularly serious pressure sores should be treated surgically. Ultraviolet therapy and infrared irradiation can reduce inflammation and sterilization, promote blood circulation and enhance cellular function, as well as dry the wound surface, reduce exudation, and facilitate tissue regeneration and repair. These are the precautions for pressure sores and some common care methods.
