Efeitos do ruído na audição de trabalhadores de lavanderia hospitalar

Abstract

Conflict of interest: non-existentheadache, physiological changes in heart rate, blood pressure, sleep disorders, several digestive, vestibular, neurological and behavioral disorders such as irritability, tiredness, decreased productivity, noise intolerance, anguish, anxiety, depression, stress, among others 2,3 . In relation to the necessary time exposition for triggering noise-induced hearing loss, the highest number of impairing rates occurs between five and seven years, decreasing loss progression rate until fifteen years when it tends to stabilize as long as exposition conditions and absence of other causative factors are kept 2,4,5 . Noise-induced hearing loss characterized by irreversible cochlear damage, in configuration of high-frequency features one of the most serious, prevalent problems for workers' health. Studies have evidenced that there has not been a reduction in work-related deafness 6 . Occupational noise is also present in hospitals, mainly in hospital laundries where continuous exposition to high levels of sound pressure may bring about permanent changes in workers' hearing INTRODUCTIONAmong all agents that may result in occupational hazard, noise certainly appears as the most frequent one, exposing a larger number of individuals.1 It is known that workers exposed to high levels of noise, above the tolerance threshold, complain about hearing loss and tinnitus, besides NOISE EFFECTS ON HOSPITAL LAUNDRY WORKERS' HEARING Efeitos do ruído na audição de trabalhadores de lavanderia hospitalarFrancisca Pinheiro Fontoura ABSTRACT Purpose: to carry out a characterize the hearing profile of workers from a hospital laundry. Method: crosscut study, with 95 workers, males and females, age averaging 38.23, held at the laundry of a public hospital located in the city of Curitiba, Parana State/Brazil. Documental laundry analysis was carried out (Medical Control and Occupational Health Program and Environmental Risk Prevention Program), noise measurement, anamnesis-applied hearing evaluation, tonal threshold audiometry, acoustic immittance, and transient otoacoustic emission testing. Audiograms were analyzed through clinical and occupational criteria (Labor Ministry/ Regulatory Norm 7). Results: noise levels found were 77.0 to 99.0 dB(A), 37.89% audiograms were altered, among them, 18.94% suggesting noiseinduced hearing loss, mainly among the clothes folders. The test of otoacoustic emissions showed no transient responses in 13 subjects with no emissions in some ears. Conclusion: the laundry is a hazardous place for hearing loss, thus preventive measures, such as Hearing Conservation Programs must be adopted.

“…Outro estudo com usuários de estéreos pessoais com idade entre 16 e 29 anos que fazem uso constante de fones de ouvido identificou que 80% dos sujeitos tem pelo menos uma queixa auditiva: as mais referidas foram sensação de plenitude auricular, diminuição 2013;VIANA et al, 2013;FONTOURA et al, 2014;MENIN;KUNZ;BRAMATTI, 2014;DUARTE et al, 2015;OLIVEIRA et al 2015;POMMEREHN et al, 2016).…”

Avaliação de intervenção educativa voltada à preservação auditiva de trabalhadores de uma lavanderia hospitalar

“…The specific scientific literature presents several studies on the development of interventions aimed at raising awareness of hearing protection in workers from different sectors, namely, (6,7) , carpentry (8) , hospitals (9,10) , civil defense -firefighters (11) , and food producing companies (12) . Hospital laundries, which are the object of the present study, are another occupational setting that presents risks to hearing (13) ; however, no studies describing educational actions in this segment have been observed. Studies conducted in hospital laundries found that noise in these places exceed the acceptable maximum level described in the Brazilian labor legislation for an 8-hour day's work (85 dBA).…”

“…Studies conducted in hospital laundries found that noise in these places exceed the acceptable maximum level described in the Brazilian labor legislation for an 8-hour day's work (85 dBA). According to these studies, the level of sound pressure observed in hospital laundries ranged from 85 to 101 dBA; they also reported that many workers did not make effective use of hearing protection devices (HPD) even though they were exposed to loud noise levels (13)(14)(15) . Therefore, the development of an awareness-raising educational practice is essential, that is, focused on development of critical consciousness of workers with respect to their health problems, stimulating the search for solutions and organization of collective action (4,16) .…”

“…Estudos revelam que ainda não houve redução dos riscos da surdez de origem ocupacional. 6 O termo "roupas hospitalares" é utilizado para diversos tipos de tecidos com diferentes cargas orgânicas e de microrganismos, utilizados tanto por pacientes quanto pelas equipes de saúde. Os tecidos são provenientes dos diversos setores de um hospital como maternidade, sala cirúrgica, banheiros, consultórios, roupas de funcionários (aventais, gorros e panos de limpeza) e dos quartos (fronhas, cobertores, toalhas, colchas, cortinas, roupas de pacientes etc.)…”
