Convulsions do not necessarily occur as soon as a fever develops after a convulsion, but the probability of occurrence is higher than normal. Therefore, early treatment of fever can effectively prevent convulsions. Convulsions triggered by high fever usually occur in young children, and are related to the immaturity of nerve cell development in children and the imperfect formation of nerve myelin sheaths. Children with a history of convulsive seizures are more likely to have a convulsion if they have a high fever and need to be treated as early as possible. When a child develops a high fever, medications such as ibuprofen or acetaminophen can be given under medical supervision to reduce the fever. If a convulsion occurs, the child should be taken to the hospital immediately for emergency treatment. At the same time to ensure that the child’s airway is open, to avoid choking and other critical conditions.
