In children with vomiting and fever, the first thing to consider is that it is triggered by factors such as excessive stomach fire and food accumulation. You can observe closely to see if the child has a red and yellow tongue, low appetite and abdominal distension. If there is such a condition, it can be judged that it is caused by accumulation of food. You can take oral solution of Si Mo Tang, Xiao Xiao Chai Gui Fever Reducing Granules, and compound Chicken Nei Jin Granules to carry out treatment. The child can also drink water with hawthorn to help improve the situation of food accumulation. In addition, if the child is also accompanied by dizziness, vomiting, high fever, twitching and spasms of the limbs, consider the fever and vomiting caused by meningitis and other factors. In this case, it is necessary to go to the pediatric internal medicine department to check whether meningitis is present. Brain CT, lumbar cerebrospinal fluid testing, and neurological signs can be done to determine this. Once meningitis is confirmed, the patient should be admitted to the hospital for anti-infection treatment with antipyretic and analgesic drugs.
