Fire boils include boils and carbuncles, and their surgical procedures include local anesthesia, incision and drainage, and dressing of the wound. 1.Local anesthesia, firstly, the patient’s local lesion area is disinfected, toweling, and then local infiltration anesthesia of the excision site is carried out using lidocaine. Note that the anesthesia needle and migration area need to be carried out in the normal tissue to prevent the spread of infection. 2. Incision and drainage. Generally, only boils and carbuncles with suppuration and fluctuating sensation need to be incised and drained, and some special areas, such as the nose and ears, cannot be incised. A scalpel is used to make a “+” or “++” shaped incision in the lesion area, and the pus is drained and the peritoneum is removed. 3. Dress the wound, place drainage strips in the wound, change the dressing frequently, and take antibiotics such as amoxicillin and cefaclor together. In addition to surgery, good hygiene is also important in preventing fire boils.
