Parents are anxious when their children have fever with vomiting, so we will briefly introduce the treatment for children with fever and vomiting. There are many causes of fever and vomiting in children, which need to be analyzed on a case-by-case basis. The most common causes are gastroenteritis or respiratory tract infection, the former with diarrhea, abdominal pain, loss of appetite, etc., and the latter with runny nose, sneezing, coughing and phlegm, generalized aches and pains, etc. If the child, in addition to vomiting and crying, will always rub his ears with his hands, with a body temperature as high as 39 degrees Celsius, suggesting that he may be suffering from otitis media. Parents should take their children to the doctor as soon as possible to identify the cause of the disease and treat it to avoid aggravating the condition. At the same time, the child can be given antipyretic treatment according to the child’s temperature, and frequent vomiting should also pay attention to the appropriate rehydration treatment to avoid dehydration. The child’s fever and vomiting need to be carefully observed by parents and friends to find the cause and respond in a timely manner.
