“…Studies have found evidence for high levels of sound pressure in NICU and inside the incubators (6,8,13) and have indicated the deleterious eff ects on the health of neonates, health care professional and family, although there is s ll a scarcity of studies in the Brazilian and interna onal Nursing literature on the subject here researched.…”

“…Loud noise causes psycho-biological eff ects in the new-born, with altera ons in the sleep cycle and wakefulness, immediate changes in vital signs, and inadequate growth and development (13) . This is in addi on to the fact that sleep disturbance in the neonate can lead to impaired immune function, decreased inspiratory muscle endurance, diffi culty in weaning from mechanical ventilation, a possible association with delirium and severe morbidity and impaired secretion of melatonin, the key circadian regulatory hormone (17) .…”

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

“…In such a nurturing and confined environment, they achieve proper neurosensory development. (1) In contrast, the premature infant, prior to 37 weeks of gestational age, spends their first months in the Neonatal Intensive Care Unit (NICU) environment, which is often a harsh, invasive and noisy environment at a time of physiological limitation and central nervous system immaturity, making them especially vulnerable to NICU environmental stress that can often continue. (2) They also have an increased need for long term intensive care, which makes them more sensitive to the negative effects of the NICU.…”

“…(2) They also have an increased need for long term intensive care, which makes them more sensitive to the negative effects of the NICU. (1) According to its definition, noise is undesirable sound and sound is vibration in a medium, usually air. When these vibrations occur at high levels sound may become harmful.…”

In this early pilot study, we sought to determine if the alteration in these physiologic effects in premature infants in response to ambient noise in the NICU could be assessed evaluating cerebral blood saturation. Three premature infants, on high flow nasal cannula oxygen support (HFNC), at less than 34 weeks of gestation were included in the study. Three variables were used to evaluate sound levels due to AAP and EPA guidelines; Leq,1h, L10,1h and Lmax,1min. All of the patients studied were found to be exposed to statistically significant noise levels (above recommendation) throughout all of the time periods measured. Noise levels were found to be similarly elevated during the 1 am and 3 pm time periods as well, though not as much as compared to the 7 am measure. A statistically significant difference was found within every patient's rSO2 levels in both hemispheres, but also in the absolute differences of rSO2. Positive significant statistical correlations were found between the average rSO2 and Leq,1h (ρ=0.14), Lmax,1min (ρ=0.18), L10,1h (ρ=0.15). Significant negative correlations were found between the absolute difference levels and Lmax, and L10, This data highlights the need for further study as to the potential impact of noise on the cerebral physiology of premature infants. Further research is needed to assess the potential long-term side effects of environmental noise on the premature infant's brain.

“…When exposed to excessive noise, the newborn body can present different responses, such as: hypoxia, release of adrenocorticotropic hormone and adrenaline in the blood stream, increase in heart rate, systemic vasoconstriction, , pupil dilation, increase in blood and intracranial pressure, increase in oxygen consumption and caloric requirements, that can lead to delay in weight gain in the long term. The noise can lead to changes in infants' states of sleep and wakefulness, making them annoyed and whining, hindering their development (3)(4)(8)(9) . Additionally, the excessively noise environment affects infants' ability to interact and can change their behavioral state, leading to "fading" and, thus, affecting in some way the bond between parents and the infant (5) .…”

Objectives: To identify levels of sound pressure level (NPS) inside the incubator and the sources of noise in that microenvironment of the Neonatal Intensive Care Unit of a university hospital. Methods: Descriptive quantitative study, conducted in incubators for the Neonatal Intensive Care Unit of a university hospital in São Paulo. The records were obtained by NPS dosimeter, totaling 261 hours, 48 hours of records of the sources producing noise. Results: There were high NPS inside the incubators. Greater Leq levels were 79.7 dBA in room A, and 74.3 dBA in room B. The main sources of noise were: water circulation fan, maintaining open doors on the incubators during periods of care, equipment alarms, and conversation among professionals close to the incubator. Conclusions: The results showed that the NPS inside the incubator are far above those recommended by regulations. Based on these results, we developed a protocol and educational program. Keywords: Noise; Intensive care units, Neonatal; Neonatal nursing; Humanization of assistance RESUMOObjetivos: Identificar níveis de pressão sonora (NPS) no interior das incubadoras e as fontes geradoras de ruído nesse microambiente de Unidade de Terapia Intensiva Neonatal de um hospital universitário. Métodos: Pesquisa quantitativa, descritiva, conduzida nas incubadoras de Unidade de Terapia Intensiva Neonatal de um hospital universitário do Município de São Paulo. Os registros de NPS foram obtidos por meio de dosímetro, totalizando 261 horas, 48 horas de registros das fontes produtoras de ruídos. Resultados: Constataram-se elevados NPS no interior das incubadoras. Maiores Leq médios foram 79,7 dBA na sala A e 74,3 dBA na B. As principais fontes de ruído foram: barulho da água do ventilador, permanência das portinholas abertas da incubadora, durante os cuidados prestados, alarmes dos equipamentos e conversa entre profissionais próxima à incubadora. Conclusões: Os resultados evidenciaram que os NPS no interior das incubadoras estão distantes do recomendado pelos órgãos regulamentadores. Com base nesses resultados, foram desenvolvidos um protocolo e programa educativo.
