Traumatic injuries can be disinfected with iodophor, which has a strong bactericidal and disinfecting effect. Iodophor can be used to disinfect wounds and mucous membranes when the body is traumatized for various reasons. Iodophor is less irritating than alcohol, and even when used on sensitive areas of the mucous membranes, it does not cause stinging or other discomfort. Therefore, iodophor is currently the preferred disinfection item after an injury. It is important to note that people who are allergic to iodine should not use iodophor for disinfection, and people with hyperthyroidism should also try to avoid iodophor. If the injury is extensive and the wound is not deep, iodophor can be used to disinfect the wound. If the injury is small and the wound is small and deep, not only disinfection but also tetanus injection is required.
