Bedridden elderly people with bedsores can be treated by changing position, disinfection and medication, and in severe cases, surgery. 1. Changing position: When bedsores appear to be ulcerated, the posture should be changed in time, and the elderly should be turned over every once in a while or a special mattress should be used to avoid further aggravation of bedsores. 2. Cleaning and disinfecting: After cleaning the ulcerated and necrotic areas, disinfecting the ulcers with iodophor will help the wounds to recover. 3. Medication: For those who are infected, antibiotic drugs such as tetracycline and metronidazole can be taken under the guidance of specialized physicians. 4. Surgical treatment: if the symptoms are more serious and the localized necrotic ulceration is more serious, the necrotic part can be removed by surgical instruments with the help of doctors.
