O equipamento portátil (ILO ECOCHECK, AUDX, entre outros) é uma outra alternativa, além dos aparelhos tradicionais (ILO 292, Byologic, Celesta, etc.) para a triagem auditiva em neonatos. Objetivo: Realizamos Emissões Otoacústicas Evocadas Transitórias com os dois equipamentos, em 88 recém-nascidos normais sem risco auditivo para observar as respostas obtidas, procurando determinar, assim, a concordância entre os dois equipamentos. The portable equipment (ILO ECOCHECK -AUDX, among others) is another alternative besides the traditional devices (ILO 292 -BYOLOGIC, CELESTA, etc.) for the auditive selection in newborn children. Aim: We have realized transiently otoacoustics emissions with both devices, in 88 normal newborn children without risk of auditive danger to observe the responses gotten with both, determining, this way, the agreement between both devices. Study design: Clinical prospective. Results: We have noticed that the newborn children who failed in ILO 292 also failed in ILO ECOCHECK; however, not all of them who failed in ILO ECOCHECK failed in ILO 292. We have also noticed that the ones who had failed in ILO ECOCHEK had showed us no response in the first analyzable band of frequency of ILO 292. Conclusion: We have concluded that the portable equipament revealed itself more rigorous in the characterization of the normal exam than the criterion of normaity used in the evalution of the conventional exam.Rev Bras Otorrinolaringol.
