Risk factors for sensorineural hearing loss in NICU infants compared to normal hearing NICU controls

Avaliação dos níveis de resposta das emissões otoacústicas em neonatos com asfixia perinatal

“…, 23 However, when analyzing the amplitude of otoacoustic emissions, this study observed lower values than those found in newborns with no risk indicators for hearing loss at birth. This indicates the possibility of damage to cochlear cells caused by tissue hypoxia, an information not taken into account for the criteria of normal otoacoustic emissions.…”

“…, 23 Entretanto, este estudo observou, ao analisar a amplitude das emissões otoacústicas transientes, valores inferiores aos encontrados em neonatos sem indicadores de risco para deficiência auditiva ao nascimento. Isso indica a possibilidade de danos às células cocleares ocasionados pela hipóxia tecidual, dado não valorizado pelos critérios de normalidade das emissões otoacústicas.…”

An initial overestimation of sensorineural hearing loss in NICU infants after failure on neonatal hearing screening

“…It is beyond the scope of this article to study the etiologic background of hearing loss. The etiologic factors associated with sensorineural hearing loss in this population are separately described [20]. We found that 1.8% of the screened NICU population had a sensorineural hearing loss or absent ABR responses.…”

Etiological factors for pediatric sensorineural hearing loss

“…However, SNHL was more likely if peak bilirubin levels coexisted with netilmicin use or if acidosis occurred when bilirubin level was high. Coenraada et al [8] studied the risk factors for SNHL in NICU infants and found neonatal hypoxia, hyperbilirubinemia requiring phototherapy, low APGAR scores, use of ototoxic drugs and meningitis as the important causative factors.…”
