Stroke patients are often paralyzed and cannot turn over and change their position by themselves, so they are most likely to develop bedsores due to the localized compression of their bodies and the decreased nutritional function of the skin of the paralyzed limbs. Decubitus ulcers, also known as pressure ulcers, are red, swollen and blistered in the early stages of the disease, and later become purplish red and begin to break down. Bed sores are more likely to occur on the back of the chest, buttocks, hip, heel and ankle, where they are compressed by weight. Prevention of decubitus sores is most important and should be done as follows: (1) Turn and massage the patient regularly, at least once every two hours. (2) Add soft cushions, air rings, sponge cushions, etc. to the areas where decubitus ulcers are likely to occur. (3) Keep the skin clean and dry. When there is urinary or fecal incontinence and vomitus, scrub them clean in time. Do not let the patient sleep directly on the rubber mat. (4) Keep the bed clean and dry, and change the bedding whenever it is wet. For patients who are incontinent, do not put the bedpan under the patient all the time for the sake of convenience. Patients with sensory impairment should not use hot water bags as much as possible to prevent burns. (5) Strengthen nutrition in the diet to ensure the supply of protein and increase the resistance of the patient’s skin. (6) For decubitus ulcers that have occurred, keep the wound surface dry, apply anti-inflammatory and muscle-generating ointments, and use physical therapy, etc. In short, to do a good job of preventing bedsores is to turn over regularly and pay attention to checking whether the skin, clothes and sheets are flat and dry when turning over; when the skin under pressure is red, rub it with the palm of your hand to promote blood circulation in the skin, so as to achieve early prevention, early detection and early treatment.
