Otoacoustic Emissions in Neonatal Intensive Care Unit for Hearing Screening

Guo Jin-feng

Abstract

Objective To evaluate the effectiveness of distortion product otoacoustic emissions for hearingscreening in neonatal intensive care unit . Methods 116 infants (232 ears) were screened by DPOAE with GSI70Automatic OAE . The outcome of DPOAE screening was compared with that of auditory brainstem response(ABR)test . Results Of 116(232ears) newborns , the co-positivity and co-negativity of DPOAE and ABR were42.19%(27/64ears) and 93.45%(157/168. The false negativity and false positivity of DPOAE were57.81% (37 /64ears)and6.55%(11/168ears). Conclusion In NICU , DPOAE screening made a high false negativity that may lead thecentral hearing loss missed , while ABR test has an important significance in first hearing screening forinfants of NICU as a reliable method.
