Newborn hearing screening in the NICU: profile of failed auditory brainstem response/passed otoacoustic emission.

摘要: Objective. Incidence of a specific pattern auditory responses, absent brainstem responses (ABRs) and present otoacoustic emissions (OAEs), in newborn hearing screening regional perinatal center neonatal intensive care unit (NICU) is described. This profile, labeled neuropathy or dyssynchrony (AN/AD), dysfunction neural/brainstem transmission that occurs individuals whose outer hairs cells are functioning normally. Although the AN/AD profile has been associated with various risk factors, incidence prediction unknown. Method. Analysis electrophysiologic measures medical record reviews first 22 months universal hearing–screening program was conducted. Association evaluated following factors: gender, gestational age, ototoxic drug regimen, low birth weight, hyperbilirubinemia, hydrocephalus, Apgar score, anoxia, respiratory distress syndrome, pulmonary hypertension, intraventricular hemorrhage, multiple birth, seizure activity, family history. Results. One hundred fifteen (24.1%) 477 infants failed ABR 1 both ears passed OAEs bilaterally. Comparisons fitting those not were negative 3 exceptions: hyperbilirubinemia who administered vancomycin furosemide. A logistic-regression analysis model to predict which would be at for either unilaterally Conclusions. Screening NICU should conducted first, followed by OAE after failure on ABR. Because found 24% this at-risk population, additional study warranted.
