The following measures can be used to deal with children with fever that does not go away and cold hands and feet: first, give the child oral rehydration salts. In some cases, the fever and cold hands and feet are due to insufficient blood circulation in the body, and oral rehydration salts should be used to correct dehydration and low blood circulation. Secondly, children need to be given antipyretic drugs, such as ibuprofen. Ibuprofen is a non-steroidal anti-inflammatory drug that can cause sweating throughout the body, which can quickly lower the body temperature. In addition, hot water can be used to soak the child’s hands and feet to promote blood circulation.
