Intensidade de ruído em hospital de 222 leitos na 18ª Regional de Saúde - PR

Abstract

Envi ronment noise pollution is common place today, at intolerable levels. In hospitals, technological developments have, as a consequence, potentially harmful noise levels. Much of the hospital noise comes from inside, rather than outside, and the major source of such noise is the Intensive Care Unit, for example equipment and hospital staff talk. Our goal with the present study was to investigate the noise level present in the different hospital environments, within a 222 bed hospital located at the 18th health zone, PR. Materials and Methods: The study was carried out in March, 2005, during a period of 24 hours, in tem different sectors. Case study: We checked environmental sound level by means of a model 1350 decibel meter. Results: The sound level found in our study was of 63.7 dB(A) in average, which exceeds the 45 dB recommended by the Brazilian Association of Technical Standards (1987). Conclusion: In the analyzed sectors, the sound level was considerably above the recommended maximum. The hospital staff should be aware of this noise level and its effects, so that they may act in a more efficient way in order to reduce this noise pollution; thus benefiting the professionals and patient recovery.

“…Although there was no significant oscillation during the observation, those changes may be clinically important to the evaluated population because ofthe gestational immaturity of the infants combined with the associated stressing agents and the increased susceptibility to the environmental stimuli which they are exposed to 2,4,7,14,18,19 .…”

Avaliação audiológica em funcionários de um hospital público expostos a ruído

“…According to the National Committee of Noise and Auditive Preservation 19 , one of the symptoms of hearing loss induced by noise, is the beginning and the predominance 4 in the frequencies of 3, 4 or 6kHz, particularly in the first 10 to 15 years of exposure and, as the lesion worsens, it afterwards Besides, in other studies, the TEOAE and the DPOAE tests proved being more sensitive regarding the identification of cochlear alteration than the tonal liminal audiometry, having the TEOAE revealed greater sensitivity to cochlear changes 5 and the DPOAE allowed the diagnosis of eventual lesion in higher levels, even in individuals with quantitatively normal hearing regarding the tonal audiometry 10,12,13,23 .…”

“…Numberless studies have indicated the extreme noise in several hospital environments, and pointed out the need for prevention, as well as, for proper guidance for the professionals, particularly regarding those involved with the area of health, where, theoretically, the awareness for silence should be of major importance [2][3][4][5][6][7] .…”

“…Several studies have recognized that even the individuals exposed to occupational noise within the normal hearing threshold, revealed alterations in the register of otoacoustic emissions, both through transient stimuli and the product distortion, evidencing the relevance of such tests for the HLIN precocious diagnosis [9][10][11][12][13] . Frequently associated to buzzing, the hearing loss can also unveil other hearing symptoms, such as hypoacusia, vertigo 14 , recruitment, besides other extra-hearing ailments, such cephalalgia, insomnia, stress, poor concentration, among others 5 . Together, such stress features increase the risk of accidents at work and may eventually give rise to multiple effects to the workers' health and wellbeing 1 .…”

A Utilização De Equipamentos De Proteção Individual Entre Trabalhadores De Enfermagem De Um Hospital Público

“…Em estudo realizado para verificar os níveis de ruído em um setor de esterilização, constatou que estes níveis estavam elevados, pois a média foi de 66 decibéis (18) , sendo que os níveis aceitáveis de ruídos são de 34 a 45 decibéis (19) . Embora não tenham sido verificados os níveis de decibéis a que os trabalhadores do presente estudo estiveram expostos, infere-se que seja necessário o uso destes EPIs, entretanto, no presente estudo nenhum trabalhador os utilizou.…”
