Cuts that expose flesh need to be thoroughly disinfected, sutured or adequately drained, proper medication, regular dressing changes and care, attention to nutrition and diet in order to get well quickly. 1. Thorough disinfection: Rinse the wound thoroughly with hydrogen peroxide and saline to remove dirt, and then disinfect the wound with iodophor to make the wound clean. 2. Suture or adequate drainage: the sooner the wound is cleaned after light contamination or clean wound is sutured, the sooner it will heal, and the suture can reduce the scar after healing, and if the tendon is injured, it should be repaired and sutured layer by layer. If the wound is large, skin grafting or flap transfer surgery may be needed to close the wound. If the wound is more than 8 hours after the injury, the best chance of suture is usually lost, or if the wound is heavily contaminated, oil gauze can be placed to drain the wound, prompting the wound to heal gradually from the bottom to the surface, and then the healing time will be relatively longer. 3. Appropriate medication: reasonable application of antibiotics to prevent wound infection, such as amoxicillin, cefaclor and so on. And need to inject tetanus antitoxin to prevent tetanus infection. 4. Regular dressing change care: after the wound is cleaned, the wound needs to be taken good care of in the later stage, the wound should not be contaminated with water, and the dressing should be cleaned and changed at regular intervals, such as dressing change. 5. Pay attention to nutrition and diet: appropriate attention to supplement high protein, vitamin food, all help wound healing.
