RESUMO
As drogas ilícitas são conhecidas pelos seus efeitos deletérios no sistema nervoso central; no entanto, elas também podem atingir o sistema auditivo, provocando alterações. OBJETIVOS:
Analisar e comparar os resultados dos potenciais evocados auditivos de tronco encefálico (PEATE) de frequentadores de grupos de apoio a ex-usuários de drogas.MÉTODO:
Estudo transversal, não experimental, descritivo e quantitativo. A amostra foi composta por 17 indivíduos divididos conforme o tipo de droga mais consumida 10 indivíduos no grupo maconha (G1) e sete no grupo crack/cocaína (G2). Eles foram subdivididos pelo tempo de uso de drogas um a cinco anos, seis a 10 anos e mais que 15 anos. A avaliação foi feita por meio de anamnese, audiometria tonal liminar, medidas de imitância acústica e PEATE.RESULTADOS:
Ao comparar os resultados de G1 e G2, independente do tempo de uso de drogas, não se observou diferença estatisticamente significante nas latências absolutas e nos intervalos interpicos. No entanto, apenas cinco dos 17 indivíduos tiveram PEATE com resultados adequados para a faixa etária.CONCLUSÃO:
Independentemente do tempo de utilização das drogas, o uso de maconha e crack/cocaína pode provocar alterações difusas no tronco encefálico, comprometendo a transmissão do estímulo auditivo.ABSTRACT
Illicit drugs are known for their deleterious effects upon the central nervous system and more specifically for how they adversely affect hearing. OBJECTIVE:
This study aims to analyze and compare the hearing complaints and the results of brainstem evoked response audiometry (BERA) of former drug user support group goers.METHODS:
This is a cross-sectional non-experimental descriptive quantitative study. The sample consisted of 17 subjects divided by their preferred drug of use. Ten individuals were placed in the marijuana group (G1) and seven in the crack/cocaine group (G2). The subjects were further divided based on how long they had been using drugs 1 to 5 years, 6 to 10 years, and over 15 years. They were interviewed, and assessed by pure tone audiometry, acoustic impedance tests, and BERA.RESULTS:
No statistically significant differences were found between G1 and G2 or time of drug use in absolute latencies and interpeak intervals. However, only five of the 17 individuals had BERA results with adequate results for their ages.CONCLUSION:
Marijuana and crack/cocaine may cause diffuse disorders in the brainstem and compromise the transmission of auditory stimuli regardless of how long these substances are used for.
