Elderly people with bedsore infections need wound dressing change, anti-infection treatment, strengthening nursing care, treatment for the underlying disease, and surgical treatment if necessary. Decubitus ulcers are caused by continuous pressure on the local tissues of the body, resulting in local blood circulation disorders, local skin ischemia, lack of oxygen appear breakage and necrosis. The main treatment measures are as follows: 1. Wound dressing: For bedsore wounds, it is necessary to clean the wounds every day, and for those who have concurrent wound infections, topical antiseptics can be used to treat the local tissues with anti-infective treatment, commonly used are povidone-iodine, silver sulfadiazine cream and so on. 2. Anti-infective treatment: when there is infection around the wound, or even complicate sepsis and other systemic infections, antibiotic treatment should be used systematically. In mild cases, amoxicillin, cefuroxime and other antibiotics can be taken, and in serious cases, intravenous ceftriaxone sodium, levofloxacin and other broad-spectrum antibiotics are needed. 3. Strengthen nursing care: daily attention should be paid to strengthen the care of the elderly, regularly change the position, reduce the local pressure. 4. Treatment of underlying diseases: because bedsores are mostly caused by long-term bed-ridden limb braking, such as fractures, paralysis, malnutrition, advanced cancer patients, need to be treated for underlying diseases. 5. Surgery: For patients with large trauma and more localized necrotic tissues, surgical treatments such as debridement and skin repair are feasible. Specific treatments vary according to individual conditions, and should be standardized according to the doctor’s prescription, and drugs should be applied under the doctor’s guidance.
