When a leg is accidentally scraped, the first thing to do is to make a proper assessment of the wound. If the wound is superficial, the alignment is particularly good, only a particularly superficial layer is scratched, basically no bleeding or very little bleeding, there is no need to go to the hospital for further treatment, use iodophor solution to disinfect thoroughly, pay attention to keep the wound dry, and properly reduce the leg movement can be. However, if the wound is deeper after scraping and does not close well, you need to go to the hospital for further treatment, and you should usually go to the hospital for thorough debridement treatment, including debridement and suturing, and intramuscular injection of tetanus antitoxin to prevent infection with tetanus bacilli.
