The medication used to heal the wound is neomycin solution or gentamicin injection. For wounds with a lot of pus or exudate and necrotic tissue, these two drugs can be used, plus cotton pads or adhesive tape to dress the wound. If the wound is already broken, the wound needs to be treated initially, then wiped with iodophor to ensure that the wound is clean and dry, and then followed by applying recombinant human epidermal growth factor gel to the surface, which can promote cell growth and also effectively prevent infection. If the wound is already dry, putting on gauze is fine. If the wound is relatively light, the blood supply is rich and the chance of infection is relatively small, simple moistening with saline is also possible. If the local tissue is swollen and bruised, in addition to using a hot towel, you can also spray Yunnan Baiyao aerosol on the wound surface.
