Otoacoustic emissions in children treated with gentamicin in a secondary hospital.

Introduction: The National Commission for the Early Detection of Hearing Loss (CODEPEH) recommends the re-evaluation of hearing in children who have suffered any potentially harmful event, such as the prescription of ototoxic antibiotics such as gentamicin. The evoked otoacoustic emissions (EOAE) are a good method for assessing the integrity of cochlear functionality.

Material And Method: A prospective study is presented, including 92 children who were treated with intravenous gentamicin for septic risk/sepsis or urinary tract infection.
