Decubitus ulcers, also known as pressure ulcers, are a symptom of prolonged pressure on the human body, resulting in ischemia, hypoxia, malnutrition, ulceration, and necrosis. Decubitus ulcers mostly occur in the lumbosacral area and sciatic nodes, and are caused by inadequate turning in bed for long periods of time. The deeper the bedsore, the more serious the condition. Early pressure, redness and plaques require prompt care to prevent infection by staying away from contaminants. If there are skin tissue defects, congestion, edema, oozing or severe ulcers, they need to be treated with medications, physical therapy, surgery and other methods. Decubitus ulcers must seek medical attention in a timely manner and be treated and medicated under the guidance of a doctor. Be sure to actively adjust your mindset, and usually do not give yourself too much pressure.
