Alcohol can be used to clean the wound, but currently we mainly use alcohol for deiodination. Routinely, local wound disinfection is performed with tincture of iodine, and the wound is cleaned with 75% medical alcohol for deiodination. If the wound is obviously split, exposing the fatty tissue below or even the muscle, alcohol is generally not used for disinfection because it will lead to liquefaction of the fat below the incision and at the same time will stimulate the muscle. If there is an obvious wound, it is recommended to go to the hospital to see a doctor first, do not use alcohol for cleaning on your own, if the contamination inside is more serious, cleaning on your own can easily lead to pollutants can not be cleaned out, and lead to late septic and infection, and sometimes there are foreign bodies can not be removed, there will be more serious complications.
