Wounds with large trauma area can be promoted to heal through medication as well as daily care. 1. Drug treatment: such as the application of recombinant human epidermal growth factor gel and other drugs to promote wound healing. When the wound is broken, bleeding, oozing, etc., the wound surface can be cleaned up with water, and then 3% hydrogen peroxide solution can be used to disinfect the local wound, which is conducive to wound healing. If the wound becomes infected, anti-infective drugs such as gentamycin ointment, ofloxacin gel and fusidic acid cream can be used to prevent infection. 2. Daily care: Avoid scratching and touching water on the wound to avoid bacterial infection and other problems, which will make the breakage serious and the healing speed slow. It is recommended to use medication under doctor’s guidance. During the wound recovery period, you can eat more food rich in vitamin C, vitamin A and protein-rich foods, which will help promote wound healing. Try to consume less spicy and irritating foods such as chili peppers.
