Whether an abdominal infection after bowel perforation surgery can be saved depends on the patient’s condition, age and whether the patient has been treated effectively. If the infection is not serious, the prognosis is good through active treatment. If the infection is serious, there is hope that the patient can be saved through effective treatment such as surgery. If the infection is mild, the patient can be treated with cefotaxime, ceftriaxone and other third-generation cephalosporins intravenously under the doctor’s guidance, and the prognosis is good and the symptoms will be relieved; if the infection is severe, the necrotic, contaminated or infected tissues can be cleared through surgery, and then cefoperazone, moxifloxacin and ornidazole are given as antibiotic drugs intravenously. In addition, if the elderly and the infection time is too long without timely treatment, it may cause peritonitis, which can easily cause toxic shock or infectious shock, which may be complicated by multiple organ failure, life-threatening, and requires active treatment. Patients with abdominal infection after bowel perforation surgery should be treated promptly and actively.
