When the patient is scratched by a tree branch, only a slight skin lesion or a small amount of bleeding, the wound can be simply disinfected and treated and stop bleeding, and then bandaged with clean gauze to stop bleeding. If the scratch site is more serious, the wound is deeper or the bleeding is larger, the patient should go to the hospital in time to debride the wound, because the branch scratch may leave dirty substances in the wound, so the wound should be disinfected and debrided thoroughly in time, and the wound is more serious, it should also be debrided and bandaged, change the medication on a regular basis and be injected with tetanus antitoxin for the prevention of tetanus. If the site of the scratch is special, such as scratching the eye, the patient should promptly go to the eye clinic for a detailed examination.
