If a patient has swelling of the ear and pus secretion, it is important to consult the otolaryngology department of a regular hospital as soon as possible for active symptomatic treatment. If there is a lot of pus, the external ear canal should be cleaned under an otoscope to clarify the tympanic membrane perforation, and if necessary, the pus should be sent for bacterial culture to select sensitive antibiotics for treatment. Amoxicillin, cephalosporins, levofloxacin, etc. are commonly used, and it is important to clarify whether there are any allergies before using the medication. At the same time, you can use hydrogen peroxide ear bath on the ears, which mainly plays the role of cleaning, and then use levofloxacin ear drops as a local anti-inflammatory, but remember to strictly follow the doctor’s instructions, do not increase the dosage and duration of medication, so as not to lead to fungal infection. Patients must ensure that their ears are clean and do not dig their own ears to avoid repeated infections and pus flow.
