Triagem auditiva na exposição ao vírus Zika

Abstract

Objective: To characterize the findings of hearing screening and describe the socio-demographic data of children exposed to the Zika virus. Method: a descriptive, observational, transversal type carried out in a public institution in Northeast Brazil. The sample consisted of 41 children born with microcephaly, of both genders, aged between 0 and 3 years, exposed to the Zika virus during pregnancy. Results: of the 41 children, 21 were male. 41.5% did not perform TANU. Of the 24 that performed, 100% were assessed with Transient Otoacoustic Emissions (TOAE) and 41.7% also performed the Brainstem Evoked Response Audiometry (BERA) automatic. A failure result was obtained in 41.7% failure with TOAE and 30% with BERA-a. There was an average time of 12 months between the completion of the Universal Neonatal Hearing Screening (TANU) and the search for diagnosis or monitoring. All mothers: performed prenatal care; 41.5% had a partner; 34.1% were from home; and 68.3% lived in the metropolitan region of the state. Conclusions: Although the Zika virus is a risk indicator for hearing loss, TANU has been performed with TOAEs, with a high failure rate in this population. The average time between birth and the diagnosis or monitoring procedure has been 12 months. The location of the home address showed little influence on the time to search for services in the hearing care program, and social issues may be more related to this data.
