The common causes of infection in the patient’s surgical incision are as follows: a. The patient’s abdominal cavity is accompanied by serious infection, such as gastrointestinal perforation, acute purulent cholecystitis, acute gangrenous appendicitis, when the inflammatory lesions in the abdominal cavity are sutured, there are more bacteria in the wound without contaminating the wound can cause wound infection. Second, if the local skin disinfection is not complete in the process of incision suturing or dressing change, resulting in a large number of local bacterial residues, can also cause redness and pain at the incision and acute infection performance, it is often necessary to strengthen the incision dressing change to promote faster wound healing. Third, the patient’s organism resistance is poor, after surgery did not try to give antibiotics to strengthen anti-infection treatment. The gradual increase of bacteria in the wound can also cause infection of the incision and delay the healing of the incision. At this time, it is necessary to actively strengthen anti-infection treatment and strengthen the incision change, in order to enable the patient’s condition to recover as soon as possible.
