Regular disinfection and dressing of the wound, keeping the wound clean and dry, and taking oral medication if necessary are necessary for the wound to heal quickly. 1. Regular wound disinfection and dressing change: no matter what kind of wound, you need to disinfect, dress and change the dressing regularly, and in the early stage, depending on the condition of the wound, you may do it once a day, so as to ensure the wound is clean, and can make the healing faster. 2. Keep the wound clean and dry: only when the wound is in a clean and dry environment, can the wound heal faster and earlier; on the contrary, it is prone to infection, which is not conducive to wound healing. 3. Oral medication: For contaminated wounds, not only regular wound disinfection and dressing changes are needed, but also oral antibiotic drugs such as cefprozil are needed to prevent infection. However, oral antibiotic drugs need to be taken under the guidance of a doctor.
