Iodophor, alcohol and hydrogen peroxide can be used to disinfect traumatic injuries. Iodophor has a good bactericidal effect on bacteria, fungi, some viruses and protozoa. Clinically, iodophor can be used for local abrasions, lacerations or burns, infections, frostbite, and septic tissue infections such as nail fungus, acute cellulitis, and dermatitis. Although alcohol has a good sterilizing effect compared to iodophor, it is more irritating and can easily cause more obvious pain to the patient, so iodophor is generally used to sterilize the wound and promote the absorption of inflammation. At the same time, you can apply antibiotic ointment, such as mupirocin ointment, to the wound, which can effectively avoid wound infection.
