For wounds with pus, it is usually necessary to drain the pus, which is beneficial to the recovery of the wound, disinfect the wound with iodophor, and take oral antibiotics to prevent infection in case of serious infection. The formation of pus in the wound is usually indicative of a wound infection, in which case the pus needs to be drained and, if necessary, incised and drained. The wound can be disinfected regularly and covered with iodophor sand strips to prevent infection. If there is a serious infection, oral antibiotics, such as the cephalosporin drug cefepime, need to be taken at the same time. It can be good to kill the bacteria and prevent the incision from getting infected. Patients with pus in the wound can consult the dermatology department and general surgery department of the local hospital and take professional doctor’s advice for treatment. Drugs should be applied under the guidance of a doctor.
