Local infection after trauma and the formation of obvious pus septicemia should be promptly treated with incision and drainage or open drainage, and pus should also be retained for bacterial smear and bacterial culture and identification to guide clinically targeted anti-infective treatment. The wound can be cleared by repeated irrigation with hydrogen peroxide and saline to remove inactivated tissues, and then the pus cavity should be filled with iodophor gauze, which should be changed daily, especially after the gauze is soaked with pus or exudate. In addition, intravenous anti-infective treatment is chosen, usually in combination with broad-spectrum cephalosporins and intravenous input of metronidazole. During the treatment period, it is also important to take the initiative to increase the nutrition of the diet, because high-protein foods and vitamin-rich foods can also promote the healing of the wound to a certain extent, and the change of medication is also very critical.
