What is the correct treatment of skin trauma and abrasions?

The correct way to deal with abrasions: If the patient accidentally abrasions, first determine the location of the abrasions, what was hit, and the depth and scope of the abrasions. If you accidentally fall down and scratch the skin of your limbs, the scope is small and shallow, and there is not much bleeding. You can disinfect yourself with iodophor, wrap yourself with dressing to prevent water and infection, and change the dressing regularly. If the abrasion is deep, the scope is large, and the amount of bleeding is large, you need to go to the hospital for medical treatment, so that the medical staff can evaluate the degree of injury and whether there is blood vessel or nerve injury. And you need to thoroughly debride, rinse with iodophor, hydrogen peroxide and normal saline, then disinfect with iodophor, bandage the wound and fix it properly. In addition, a tetanus vaccine is needed.
