Decubitus ulcers with a rotten hole indicate serious tissue necrosis, and can be treated with debridement, diligent turning, and keeping the area dry and breathable. 1. Decontamination: Bedsores are caused by long-term pressure on local tissues and necrosis of skin and muscle tissues, and a rotting hole indicates that the degree of tissue necrosis is more serious. At this time, it is necessary to remove the necrotic tissue, clean up the necrotic tissue, and use iodophor or medical alcohol and other disinfectants to disinfect. 2. Turn over diligently: Since there is a direct causal link between the onset of decubitus ulcers and the long-term pressure on the patient’s skin, nursing staff should help the patient to turn over diligently and change the position of the bed frequently, so as to avoid the long-term pressure on a certain piece of localized skin and alleviate the symptoms of decubitus ulcers. 3. Keep the skin dry and breathable: nursing staff should avoid the patient’s skin being in a wet environment for a long time, pay attention to keeping it dry and breathable, clean and disinfect the bedsore area and cover it with disinfected gauze every day, so as to promote the healing of the wounds in the area of the patient’s bedsore. It is recommended that when a patient’s bedsore breaks out, he or she should go to the hospital in time and be treated under the operation of a professional doctor.
