If a patient develops gastroenteritis and has significant nausea, vomiting, acid reflux, heartburn, etc., with the number of vomiting being 3 or more times a day and the number of diarrhea being 3-5 times or more, he or she must be treated with an infusion, the first thing that should be infused is an anti-inflammatory drug. If the blood count shows a significant inflammatory infection, levofloxacin, etimesine sulfate, cephalosporins, penicillin family and other drugs can be applied, all of which can have an anti-inflammatory effect. Certain proton pump inhibitors or H2 receptor blockers, such as rabeprazole, pantoprazole, omeprazole, etc., can also be applied, and glucose water and saline should also be supplemented for rehydration therapy and correction of electrolyte disturbances.
