OBJETIVO: Verificar o nível de ruído da Unidade de Terapia Intensiva Neonatal e identificar suas fontes. MÉTODOS: Estudo quantitativo, descritivo e exploratório, conduzido em uma Unidade de Terapia Intensiva Neonatal de São Paulo. A coleta de dados ocorreu de abril a maio de 2005, utilizando um dosímetro para 96 horas de registro do nível de pressão sonora e 9 horas de observação, para identificar as fontes de ruído. RESULTADOS: Registrou-se Leq entre 61,3 a 66,6 dBA, sendo maior nos dias do final de semana. Os valores dos picos variaram de 90,8 a 123,4 dBC, sendo mais elevados no período noturno. As principais fontes foram: alarme dos ventiladores, dos oxímetros, conversa entre profissionais e pais e outros. CONCLUSÃO: Considerando os efeitos deletérios do nível elevado de ruído sobre neonatos e equipe de saúde, os resultados demonstram a necessidade de intervenções em algumas rotinas e na conduta dos profissionais e familiares.

Background: Peak sound levels during sleep can compromise the development of hospitalized infants. Quiet time is a strategy implemented in neonatal units to promote the sleeping of neonates by reducing noise levels, luminosity, and handling during particular periods of the day. Purpose: To determine the impact of quiet time on reducing sound levels and increasing total sleep time. Methods: This longitudinal study was conducted at a neonatal intermediate care unit with a convenience sample of 12 premature infants. Four times per day, 60-minute quiet times were provided in the neonatal unit. Sleep-awake states and sound levels were evaluated during quiet times as well as 60 minutes before and afterward. Polysomnography was used for sleep-awake state assessment, and a noise dosimeter was used to check sound levels every 24 hours. Results: The preterm infants had a corrected gestational age of 35.0 ± 1.5 weeks and weighed 1606.0 ± 317.8 g. Total sleep time was highest during quiet time (P = .005). Premature infants remained awake for longer following quiet times (P = .005). There was also a reduction in sound level during quiet times compared with the other time frames (P = .006). No statistically significant relationship was found between total sleep time and sound levels more than 24 hours. Implications for Practice: Quiet time is a nursing intervention that should be implemented in all neonatal units. Implications for Research: Future research should use a greater sample size and other factors that influence sleep should be further investigated.

Pinheiro EM, Silva MJP, Ângelo M, Ribeiro CA. The meaning of interaction between nursing professionals and newborns/families in a hospital setting. Rev Latino-am Enfermagem 2008 novembro-dezembro; 16(6):1012-8. This study aimed to understand the meaning of the nursing team's communication with newborns and families during care delivered in a neonatal unit and also to develop a theoretical model. Symbolic Interactionism andHargie's model were used as theoretical and Grounded theory as the methodological reference framework. The study was carried out at the nursery of a hospital in São Paulo, SP, Brazil. The study sample was composed of three nurses and four nursing auxiliaries. The theoretical model Being mediated by the strength of motivation was based on findings and revealed the role the nursing professionals' motivation played during interactions with newborns and families. The conclusion is that more humanized interactions with newborns and familiesresult from the nursing professionals' motivation. Research has showed that an infant's hospitalization process is a stressing experience for parents and that it is very difficult for them to be apart from their child (3)(4) .

The goal was to identify sound pressure level (SPL) at the neonatal intensive care unit (NICU) and inside the incubator of a teaching hospital of a public university from São Paulo -SP, Brazil. SPL inside the NICU and the incubator were measured using four dosimeters in January/2010. SPL at the NICU varied from 52.6 dBA to 80.4 dBA and inside the incubator, from 45.4 dBA to 79.1 dBA. SPL both at the NICU and inside the incubator are above the recommended values, but levels were higher at the NICU than inside the incubator.Although there are some specific factors related to SPL inside the incubator, the NICU and incubator acoustic features present a system: an increase/decrease in SPL at the NICU usually tends to increase/decrease SPL inside the incubator. The study points to the need for simultaneous monitoring of SPL at the NICU and inside the incubator. Evidenciou-se que tanto o NPS da UTIN como o do interior da incubadora estão acima dos recomendados, sendo mais altos na UTIN do que na incubadora. Embora haja alguns fatores específicos relacionados ao NPS no interior da incubadora, perfis acústicos da UTIN e da incubadora são como sistema: elevação/redução do NPS da UTIN, geralmente, tende a elevar/reduzir o NPS no interior da incubadora. Portanto, pode-se concluir que o presente estudo aponta para a importância do monitoramento simultâneo dos NPS da UTIN e do interior da incubadora.Descritores: Ruído; Terapia Intensiva Neonatal; Enfermagem Neonatal; Humanização da Assistência; Recém-Nascido.

RESUMOO obje vo deste estudo foi verifi car o conhecimento e a percepção de profi ssionais de Unidade de Terapia Intensiva Neonatal (UTIN) sobre as repercussões do ruído ao neonato, família e profi ssionais, antes da implementação de um programa educa vo. Trata--se de uma pesquisa descri va, quan ta va, realizada em Unidade de Terapia Intensiva Neonatal de um hospital de São Paulo, com 101 profi ssionais. Foram u lizados: ques onário para a coleta de dados, e os testes de Qui-quadrado e t de Student para a associação entre as variáveis. Os profi ssionais idenfi caram a UTIN como muito ruidosa (44,9%), perceberam os efeitos desse ruído durante e após a jornada de trabalho (67,4%) e u lizaram estratégias para amenizá-lo. Embora os profi ssionais desconheçam a legislação sobre o ruído no ambiente hospitalar, iden fi caram repercussões para si, recém-nascido e família. Os resultados apontaram para a necessidade de orientar a equipe quanto à legislação, prevenção de ruído e reorganização das prá cas assistenciais e estrutura
