The treatment of a cut must be determined by the depth, or severity, of the injury. If the wound is large, first of all, after the wound is strictly disinfected, a wound debridement suture must be given, so that the skin can be aligned and the wound can grow faster. If the wound is deep, an injection of tetanus antitoxin must also be given to prevent infection by the tetanus bacillus. In addition, antibiotics should be applied for 2-3 days to prevent bacterial infection. After wound debridement and closure, the wound should be disinfected and the dressing changed regularly. If possible, topical recombinant epidermal growth factor can be given at the time of dressing change, which can promote the growth of epidermis. If it is an epidermal abrasion, not cracked, not sassafras deep, usually apply hydrogen peroxide, saline and povidone-iodine, after disinfecting the wound, keep the wound ventilated, do not bandage, the wound will also be faster. If you want to promote its growth, you can also use recombinant epidermal growth factor, can promote the growth of the wound epidermis at the same time, but also minimize the role of the scar.
