Knife wounds are relatively sharp wounds, which can then be treated with proper debridement followed by suturing, which is the best way to treat knife wounds and heal faster. Local spraying of recombinant human epidermal growth factor can promote fresh granulation tissue growth and cell growth to speed up the healing process. If the wound is deep, the wound needs to be flushed with iodophor as well as saline and then sutured. The wound needs to be changed on time, and the wound needs to be kept dry and breathable to avoid getting water in it to avoid infection. If the wound becomes infected or even septic, further surgery is required.
