Fever leading to vomiting suggests that the patient be treated with intravenous anti-inflammatory fluids, as the patient with fever loses a lot of body fluids after vomiting, leading to severe dehydration and even deficiency in the body, accompanied by ionic disorders and acid-base imbalance. On the one hand, anti-inflammatory treatment should be given, and on the other hand, a large amount of fluid should be actively rehydrated to correct the ionic disorder and acid-base balance, and antiemetic injections such as Gastrodia should be given as symptomatic treatment. It is recommended that fluid, easily digestible food should be the mainstay, while paying attention to rest. With effective drug treatment, the patient’s fever and vomiting symptoms will be relieved. If the symptoms do not improve with symptomatic treatment, the cause should be further clarified at the hospital, especially the vomiting caused by cerebral edema due to neurological infection should be excluded.
