          Abstract

          Os níveis de ruído hospitalares encontram-se excessivamente elevados, especialmente no ambiente de UTI, em decorrência dos inúmeros alarmes e equipamentos, além da conversação da própria equipe hospitalar. Diante disso, esse ambiente, que deveria ser silencioso e tranqüilo, torna-se ruidoso, transformando-se em um grande fator de estresse e podendo gerar distúrbios fisiológicos e psicológicos tanto nos pacientes como nos funcionários dessa unidade. OBJETIVO: O objetivo deste estudo foi verificar o nível de pressão sonora equivalente em uma UTI geral, procurando estabelecer o período de maior exposição e comparando os resultados com as recomendações nacionais e internacionais. FORMA DE ESTUDO: Estudo observacional. MATERIAL E MÉTODO: Medição do ruído ambiental da UTI do Hospital São Paulo através do analisador de ruído modelo 2260 (Brüel & Kjaer), em período total de 6.000 minutos e aferições a cada 27 segundos, configurado da seguinte forma: tempo de resposta rápido (Fast), medindo em decibel o nível de pressão sonora e usando a ponderação em freqüência A, de setembro de 2001 a junho de 2002 e sem o conhecimento dos funcionários do setor. RESULTADOS: O nível de pressão sonora equivalente (Leq) apresentou média de 65,36 dB(A) variando de 62,9 a 69,3 dB(A). Durante o período diurno a média do Leq foi de 65,23 dB(A) e para o período noturno, 63,89 dB(A). O L FMax encontrado foi de 108,4 dB(A) e o L FMin de 40 dB(A). CONCLUSÕES: O nível de ruído encontrado nessa UTI está acima do recomendado pela literatura em todos os períodos analisados. Dessa forma, as fontes produtoras de ruído excessivo precisam ser melhor identificadas para que possam ser tomadas as devidas medidas para atenuação desse ruído e tornar esse ambiente um local mais silencioso, beneficiando a função laborativa dos profissionais e a recuperação dos pacientes.

          Noise levels in hospitals are excessively high, especially in the ICU environment, because of the numerous alarms and equipment, in addition to the conversation of the hospital staff itself. For this reason, this environment, which should be quiet and calm, has become noisy, thus converting into a major stress factor, likely to cause physiological and psychological disorders in both inpatients and the unit personnel. AIM: The purpose of this study was to assess the equivalent noise pressure level in a general ICU, in an attempt to establish the period of greatest exposure and to compare the results to both domestic and international recommendations. STUDY DESIGN: Observational study. MATERIAL AND METHOD: Measure the ambient noise in the ICU of Hospital São Paulo using a noise analyzer model 2260 (Brüel & Kjaer) for a total period of 6.000 minutes, at a rate of one reading every 27 seconds, was carried out with the following configuration: fast response time, measuring the noise pressure level in decibels with A-frequency weighting, from September 2001 to June 2002, without knowledge by the sector personnel. RESULTS: The average equivalent noise pressure level (Leq) was of 65.36 dB(A) ranging from 62.9 to 69.3 dB(A). During the day, the average Leq was of 65.23 dB(A), and at night 63.89 dB(A). L FMax was found to be 108.4 dB(A) and L FMin of 40 dB(A). CONCLUSIONS: The noise level found in this ICU is above the recommended by the literature during all the periods examined. Thus, excessive noise sources need to be better identified so that proper steps may be taken to reduce this noise and make this environment more silent, thus improving the professionals' work and the patients' recovery.

          Noise pollution in the anaesthetic and intensive care environment.

          Noise in the operating theatre, recovery room and intensive care unit is above internationally recommended levels. The psychological and physiological effects of noise are reviewed. Equipment and conversation among the staff are major sources of noise in these areas. Equipment design, modification of nursing care procedures, and increased awareness of noise created by the staff may be effective in reducing noise pollution in these areas.

            Noise levels in an urban hospital and workers' subjective responses.

            Internal noise levels were measured in a 232-point grid that encompassed the main building of a major University Hospital in Valencia, Spain. Most noise equivalent sound levels that were obtained exceeded 55 dBA, and in some instances these sound levels were very high. Hospital workers' subjective responses to noise were evaluated with a self-answered questionnaire. A total of 295 workers volunteered to participate. Their answers revealed that the most important noise sources were located primarily inside the hospital. Noise levels were perceived to be sufficiently high to interfere with their work, and noise levels were also thought to affect patients' comfort and recovery. Most subjects thought it feasible to reduce noise levels in the hospital, and some preventive measures were proposed.
