Pressure sores are pressure injuries. Wound care methods include keeping the skin clean, changing positions regularly, and adjusting the daily diet. 1. Keep the skin clean: keep the affected area clean, wipe with warm water, do not use force when wiping, if there is incontinence, it should be cleaned in time, and apply skin cream to reduce irritation and keep the skin dry. 2. Regularly change the posture: should regularly change the posture, such as changing the sitting position or often turn over, to avoid a position for too long, to prevent local pressure, and to replace the soft cushion or foam cushion. 3. Adjust the daily diet: the daily diet should be adjusted to avoid eating stimulating food, eat more food rich in protein and vitamins, and ensure sufficient water every day to prevent dehydration. After the pressure injury, when the symptoms are more obvious, but also follow the doctor’s advice, active treatment, safe and reasonable use of medication, do not take medication without authorization.
