Abstract:

ObjectiveTo investigate the risk factors for the failure of newborn in hearing screening.MethodsA total of 1 262 neonates were tested for hearing by otoacoustic emissions(OAE) and automatic auditory brainstem response(AABR) from January 2014 to July 2018 in our hospital. All the data of the newborn and their mothers were analyzed retrospectively. The electronic medical record includes: neonatal gestational age, neonatal gender, mode of delivery, maternal age, neonatal bilirubin encephalopathy, neonatal asphyxia, hyperbilirubinemia, and premature rupture of membranes. Univariate and multivariate logistic regression analysis was used to explore the risk factors affecting hearing loss.ResultsIn the 1 262 cases, 64 cases(5.07%) failed in the hearing screening, of which 36 cases(56.25%) failed in both ears, 15 cases(23.44%) failed in the left ear and 13(20.31%) in the right ear. Univariate and further Logistics regression analysis showed that gestational age <32W, neonatal bilirubin encephalopathy, neonatal asphyxia, hyperbilirubinemia, and premature rupture of membranes were independent risk factors for neonatal in failure hearing screening(P<0.01).ConclusionGestational age <32W, neonatal bilirubin encephalopathy, neonatal asphyxia, hyperbilirubinemia and premature rupture of membranes are risk factors for neonatal hearing loss. Hearing screening measures should be adopted to make early detection and intervention in order to reduce the incidence of hearing loss in the newborn.
