The following treatments are commonly used after intestinal bacterial infection: First, antibiotic treatment. For relatively mild patients without fever and elevated blood picture, just abdominal pain and diarrhea, antibiotic treatment with levofloxacin, metronidazole, tinidazole, etc. can be applied. If the infection is more severe, with fever accompanied by elevated white blood cells, broad-spectrum antibiotics, such as cephalosporins and penicillins, can be applied. Second, Chinese herbal medicine can be used for treatment. The Chinese medicine can be administered as a drip, such as Xiyamping injection, or as an oral medicine, depending on the patient’s specific condition. Thirdly, in addition to this, symptomatic treatment is needed. Patients with more severe diarrhea also need to supplement ions and fluids. If the patient is accompanied by fever and other symptoms, antipyretic drugs are also needed.
