The treatment of acute gastroenteritis is usually determined according to the specific condition. For example, when it is determined that it is bacterial infection, effective antibiotics should be used in time to control the infection. Berberine, or compound sulfamethoxazole, or cephalosporins, or quinolones can be used. For patients with gastrointestinal mucosal injury, drugs such as Biqi or SmithKline can be used. For diarrhea caused by harmful bacteria, probiotics can be properly used to regulate the intestinal flora. If the patient has intestinal spasm and obvious abdominal pain, atropine or anisodamine can be temporarily used for spasmolysis and pain relief and symptomatic treatment. When patients have electrolyte disorder and severe dehydration, they need intravenous infusion to correct the water electrolyte disorder.
