Ear infections in children are mainly manifested clinically as acute otitis externa or acute otitis media, and the medication can be decided according to the severity of the child’s condition. If the child’s symptoms are mild, oral cephalosporin antibiotics are often sufficient, including oral cefaclor and levofloxacin ear drops as an ear bath for local anti-inflammatory treatment. If the child’s symptoms are more serious, cephalosporin antibiotics need to be administered quietly, and cefuroxime or cefoperazone is commonly used in clinical practice. Oral Oronema drops are also needed to promote the drainage of fluid in the middle ear cavity. Local anti-inflammatory ear baths with levofloxacin ear drops are also needed. Some children may develop a fever, so oral ibuprofen suspension is needed to reduce the fever, and the child should be allowed to drink more water. In addition, during the onset of the disease, care should be taken not to get water into the external ear canal to avoid aggravating the infection.
