Triagem auditiva em recém-nascidos internados em UTI neonatal

Abstract

Objective: Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Women s Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors.Methods: 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The result was considered normal when the newborn showed response to a 35dBNA signal bilaterally. The prevalence of AABR impairment and the odds ratio were analyzed with a 95% confidence interval using bivariate analysis. To identify the independent risk factors for hearing alterations, multivariate analyses were used with logistic regression.Results: The prevalence of AABR impairment was 10.2%, of which 5.3% was unilateral and 4.9% bilateral. From the multivariate analyses, the following observations were made: family history of congenital hearing loss (OR = 5.192; p = 0.016), craniofacial deformity (OR = 5.530; p < 0.001), genetic syndromes associated with hearing loss (OR = 4.212; p < 0.001), weight below 1,000 g (OR = 3.230; p < 0.001), asphyxia (OR = 3.532; p < 0.001), hyperbilirubinemia (OR = 4.099; p = 0.002) and use of mechanical ventilation (OR = 1.826; p < 0.031) were the indicators that best characterized the group at risk for hearing impairment. Conclusions:The prevalence of hearing impairment using AABR is high. Therefore, it is essential for all newborns who present isolated or associated risk factors to undergo hearing screening in situations in which it is not possible to have universal hearing screening.

Analysis of transient otoacoustic emissions and brainstem evoked auditory potentials in neonates with hyperbilirubinemia

“…1,2 Many authors have highlighted the harmful effects of biliary pigment impregnation of central and peripheral auditory pathways. [3][4][5] Hyperbilirubinemia is toxic for endocochlear hair cells, basal nuclei and central auditory pathways. 4 The intensity of hearing loss may vary and it may or may not be reversible.…”

Investigação etiológica da deficiência auditiva em neonatos identificados em um programa de triagem auditiva neonatal universal

“…Some of the causes are neonatal anoxia, prematurity, hyperbilirubinemia, low birth weight, ventricular hemorrhage and long ICU stays 24,25 . A Brazilian study has shown that some perinatal factors such as low birth weight, anoxia, hyperbilirubinemia and mechanical ventilation were significant for hearing loss 26 .…”

Programa de triagem auditiva seletiva em crianças de risco em um serviço de saúde auditiva de São Paulo

“…A coleta de dados das condições socioeconômicas e culturais das famílias encaminhadas para a triagem pode auxiliar em novas estratégias para aumentar o comparecimento/adesão ao programa de identificação e intervenção precoce, e triagem auditiva 8,24 . Os resultados da amostra apontam que aprofundar o conhecimento das características da população a que se destina o programa de triagem pode facilitar o acesso e, assim, a divulgação e o conhecimento do serviço 13,25,26 .…”
