Patients with pressure sores are commonly found in middle-aged or elderly people, or in patients with limb insufficiency or paralysis. The underlying cause is pressure on the trabecular surface and pressure on the skin, resulting in localized redness and swelling. If the skin is red in stage I, it is fine as long as the patient is turned over regularly and the skin is kept free of pressure for a long time. If the pressure sore is in stage II and blisters have formed, the trauma should be disinfected locally, and after disinfection, medications should be applied, including anti-infective medications and medications to promote skin healing, or biological dressings can be applied to cover it. However, if the pressure sore reaches stage III, the entire skin layer has been compressed, and the deep tissue and deep fat layer have been reached, the first step is to ensure that the skin is turned over and the wound is treated locally with topical medication. It is possible that care at home is no longer sufficient and further treatment in the hospital is needed, including the application of local far-infrared therapy devices, baking lamps, and baking electricity. In the case of stage IV pressure ulcers, which have reached the skeletal, tendon, and muscle layers, it is necessary to go to the hospital for surgical treatment, and care includes the patient’s urinary and fecal care. Whether it is a stage I or stage IV pressure sore, it is divided into three major segments of care, as follows: 1. Avoid pressure on the skin; if it is under long-term pressure, the skin will certainly not be well treated; 2. Keep the skin locally clean, including diligent scrubbing and local disinfection treatment; 3. Pressure sores are most commonly found in the sacrococcygeal region of the buttocks, which are most likely to be contaminated by urine and feces, so it is important to keep the area clean and do a good job of It is important to maintain local cleanliness and do a good job of cleaning up urine and feces.
