Fever represents the main cause of admission to the emergency room in older people pediatric. It occurs in the presence of a wide range of pathologies, from infectious forms (the most common, viral or bacterial) up to more complex and/or systemic forms (such as inflammatory or neoplastic ones). The drugs currently indicated for the management of fever in children are: paracetamol and ibuprofen. There are no recent studies conducted in pediatric population, who have demonstrated the greater effectiveness of therapy with paracetamol or ibuprofen, The objective of our study is, therefore, to identify which therapy is most appropriate for controlling body temperature e of associated symptoms in pediatric patients arriving in the emergency room with fever.
