Determining the Frequency of Hearing Loss and Its Risk Factors in Neonates Admitted to the Neonatal Unit: A Hospital Study

[摘要] Background and Objectives The prevalence of hearing loss in infants with a risk factor is higher than ininfants without a risk factor. The aim of this work is determine the prevalence of hearing loss and identifythe most significant risk factors for hearing impairment in neonates hospitalized at neonates unit.Subjects and Methods A total of 450 infants admitted to the neonatal unit of Abuzar hospital in Ahvazwere evaluated for hearing in October 2020 to April 2020. The hearing screening tests performedwere Transient Evoked Otoacoustic Emissions (TEOAES) and the automated auditory brain stem response(AABR). Risk factors include birth weight less than 1500g, prematurity, family history of hearingloss, consanguineous marriage, hyperbilirubinemia, mechanical ventilation for more than 5 days,asphyxia, autotoxic drugs, sepsis, hypoglycemia and Apgar less than 5 were in one minute after birth.Results twenty neonates (4.4%) had different type of hearing loss. MechanicalVentilation more than 5 days, sepsis, asphyxia, hyperbilirubinemia and Apgar<5 were considered riskfactors of hearing loss.Conclusion The prevalence of hearing loss in neonate with risk factor is significant that raises the needfor hearing screening using TEOAE and AABR simultaneously. It is recommended that children withhearing loss risk factors be evaluated for hearing periodically.
