Otitis media refers to acute or chronic inflammation of the tympanic membrane, tympanic cavity, or mastoid cavity. Whether otitis media requires intravenous (IV) therapy mainly concerns acute suppurative otitis media. Generally, if the symptoms of otitis media are mild, such as ear pain without ear discharge, fever, headache, etc., IV therapy is usually not necessary. If the patient's symptoms are severe, such as intense ear pain, discharge from the ear, or even fever and other systemic symptoms, then IV anti-infection treatment should be considered. It is also common to perform a complete blood count to check the number of white blood cells; a high white blood cell count further supports the need for IV anti-infection treatment.
