The main steps of debridement are adequate exposure of the wound, removal of foreign bodies, local disinfection, and suturing. 1. Fully expose the wound: use sterilized forceps or scalpel to fully expose the patient’s wound, disinfect it with iodophor solution, spread the towel, perform local infiltration anesthesia, and then start to explore the specific situation. 2. Removal of foreign bodies: After exposing the wound, use forceps to remove large foreign bodies and use saline to flush the wound clean. 3. Local disinfection: After removing the foreign body, use hydrogen peroxide to rinse the wound locally, which can play the role of disinfection. After disinfection is completed, saline is used to rinse again to remove the residue of hydrogen peroxide. 4. Suture: After local disinfection is completed, the wound is sutured in layers. Note that for firearm injuries, animal bites and other wounds, can not be sutured together. After the debridement treatment, you need to change the dressing and remove the stitches regularly, take antibiotics such as cefuroxime and levofloxacin to prevent infection, and inject tetanus antitoxin to prevent and treat tetanus. The debridement treatment should be carried out under the operation of professional doctors, avoiding blind treatment, so as to avoid serious consequences.
