First, do the necessary examinations based on the basic condition of the patient. The purpose of doing the examination is to further understand the trauma and clear up the trauma to have a purpose. For example, foot bone infection is good for determining whether there is bone destruction, whether osteomyelitis is suspected, etc. The way to clear the wound is different in different cases. Second, grasp the timing of clearing up. For different types of diabetic foot trauma, the timing of debridement is different, like dry gangrene with severe ischemia, which should be debridged after the lower limb circulation is improved, otherwise it will still be infected after debridement. In the case of wet wounds, the earlier the wounds are cleared, the better. Third, disinfection should be done. Disinfection needs to be done in a sterile environment and a suitable disinfectant should be chosen. Colorful disinfectant should be used sparingly because it is not conducive to identifying whether the tissue is infected or healthy. Fourth, a nibbling method of debridement should be adopted, and not all of it should be cleaned at once. The principle is to clear the wound from the outside to the inside, layer by layer slowly inward. If you are too hasty, you will inevitably injure the healthy tissues, and given the characteristics of diabetic wounds, the chances of infection of healthy tissues are greater, and the patient will lose more. Fifth, the debridement should be carefully and carefully explored. If an invisible inflammatory fistula hole or sinus tract is found, it should be thoroughly drained, which can be done with a strip of gauze soaked with medicine. If it is not thorough, the inflammation will be difficult to control and will not serve the purpose of debridement. Sixth, the wound treatment after debridement. It is not recommended to prematurely suture or close the wound, because practice has shown that open wounds combined with daily nibbling debridement and medication changes heal faster and promote cell growth and reproduction, naturally growing healthy tissue. On the contrary, if the wound cannot be made sterile after closure, anaerobic bacterial infection will easily occur under the wound and the treatment will fail. Sixth, the effect of Chinese ointment is better than using dressing alone. After wound debridement, topical application of Chinese ointment, which has the effect of eliminating decay and regenerating muscle, will be more helpful to the treatment of the wound, and there will be no secondary damage caused by dressing replacement. The above are the main points to note for diabetic foot debridement, at the same time I told you that the treatment of diabetic foot is a systematic and comprehensive treatment plan, the specific operation is very complicated, it is recommended to go to the local professional diabetic foot specialist to receive treatment, so that the doctor is difficult to make mistakes, so that patients can avoid the more serious situation!
