The following measures can be used to treat children with fever that does not pass stools. First of all, children should be given oral rehydration salts in time because fever can cause excessive water loss in the body. If children lose too much water in their intestines, they will have dry stools, which will cause them not to pass stools. Secondly, apply antipyretic drugs to children. If the fever exceeds 38.5℃ in the axilla, acetaminophen should be applied to reduce heat treatment in time. In addition, to clear the heat accumulation in the intestinal tract of children, Wang’s Bao Chi Wan can be applied to clear the heat accumulation in the intestinal tract, thus improving the symptoms of children not passing stools and fever, because Wang’s Bao Chi Wan contains rhubarb and baicalin.
