Efeito de fármacos ototóxicos na audição de recém-nascidos de alto risco

Abstract: OBJETIVOS: Calcular a incidência da perda auditiva sensorioneural (PASN) em recém-nascidos de alto risco, verificar se existe associação causal entre o uso de fármacos ototóxicos em neonatos de alto risco e a PASN e estabelecer a frequência das mutações genéticas relacionadas à PASN em neonatos de alto risco. MÉTODOS: A pesquisa foi uma coorte retrospectiva e prospectiva realizada em 250 crianças. Foi realizada coleta de dados em prontuários e com os responsáveis, triagem auditiva por emissões otoacústicas-pro… Show more

“…In addition to blood transfusion, the infant was exposed to ototoxic medication (gentamicin) which can cause different degrees of damage, with cochlear hair cells damage being typical 42 . A close relationship between hearing impairment and use of ototoxic medication has been reported for newborns 30,43,44 . The prevalence of hearing loss obtained in this study was more than evident in research conducted at the same hospital 5 , and the value obtained could have been higher, since two newborns did not undergo the audiological diagnosis.…”

“…Another study, conducted in a public hospital in Belo Horizonte, with 346 newborns with very low weight, also found a prevalence of 3.0% of hearing loss in this population (10) . Nevertheless, a study conducted with 311 high-risk newborns followed at a School Maternity and two public hospitals in São Paulo, reported incidence of 11.6% of sensorineural hearing loss pointing to reports in the international literature of values close to those obtained by the authors (27) .…”

“…The same methodology was followed in another study conducted on 250 newborns (14) . In addition, that study also employed audiometry with visual reinforcement, tympanometry, and brainstem auditory evoked potential test, conducted at 3 time points (at the time of discharge from hospital, after three months of discharge, and after six months of discharge).…”
