“…In the neonatal period it has a connection with the maturation of CNS, memory consolidation and learning, maintaining energy, increased protein synthesis and secretion of growth hormone (GH). The mechanisms involved in sleep and wakefulness are present even before birth, and these are developed thanks to the circadian cycle (CC), which like other biological cycles is characterized by maintaining physiological functions 1,7,10 . The CC is generated at [18][19][20] th week of gestation in the anterior hypothalamus, specifically in the suprachiasmatic nucleus.…”

The aim was to describe current reports in the scientific literature on sleep in the intensive care environment and sleep deprivation associated with painful experiences in premature infant. A systematic search was conducted for studies on sleep, pain, premature birth and care of the newborn. Web of Knowledge, MEDLINE, LILACS, Cochrane Library, PubMed, EMBASE, Scopus, VHL and SciELO databases were consulted. The association between sleep deprivation and pain generates effects that are observed in the brain and the behavioral and physiological activity of preterm infants. Polysomnography in intensive care units and pain management in neonates allow comparison with the first year of life and term infants. We have found few references and evidence that neonatal care programs can influence sleep development and reduce the negative impact of the environment. This evidence is discussed from the perspective of how hospital intervention can improve the development of premature infants.Keywords: sleep, pain, prematurity, polysomnography, neonatal intensive care.RESUMO O objetivo foi descrever o estado atual na literatura científica sobre privação do sono associado a experiências dolorosas no prematuro e o papel na evolução do sono em ambiente de terapia intensiva. Realizou-se uma busca sistemática para estudos sobre sono, dor, prematuridade e programas de atenção ao neonato. Foram consultados as bases Web-of-Knowledge, MEDLINE, LILACS, Biblioteca Cochrane, PubMed, EMBASE, Scopus, BVS e SciELO. A associação entre privação do sono e dor gera efeitos que são observados na atividade cerebral, fisiológica e comportamental dos prematuros. A polissonografia nas unidades intensivas e o manejo da dor em neonatos permitem comparação no primeiro ano de vida com crianças nascidas a termo. Encontraram-se poucas evidências de que programas de cuidado neonatal podem influenciar o desenvolvimento do sono e diminuir o impacto negativo do ambiente. Estas evidências são discutidas na perspectiva de como a intervenção hospitalar pode melhorar o desenvolvimento do prematuro.Palavras-chave: sono, dor, prematuridade, polissonografia, terapia intensiva neonatal.In recent decades there has been a considerable increase in the number of premature births and in the survival rate of these babies as a consequence of also increasing the effectiveness of intervention in Neonatal Intensive Care Unit (NICU). This relatively recent phenomenon has opened various fronts of research on the development of the fetus outside the uterus and its challenges. Among the areas that have aroused more interest and generated publications are the investigations on the development of sleep and pain perception and the future implications of sleep deprivation and exposure to pain at early ages. The uterine environment is suitable for the full growth and development of the human fetus site. The challenge of preterm birth and hospitalization in the NICU promotes an abrupt environmental difference for newborns which can bring challenges for future development. The inst...

“…The different stages of sleep are essential for the homeostasis of premature infants, because they establish relations with important physiological and neurological activities (3,9) . In the quiet sleep, decreased basal metabolic rate occurs, which promotes replenishment of energy reserves as well as promote cellular repair, in the active sleep brain activation occurs, which is essential for the structural maturation of the central nervous system (10)(11) . It is noteworthy that the indeterminate sleep cannot be considered as quiet or active, it is characterized as the transition between these two types of sleep patterns (12) .…”

Objective:To compare the total sleep time of premature infant in the presence or absence of reducing sensory and environmental stimuli in the neonatal unit. Method: Longitudinal study in a Neonatal Intermediate Care Unit of a public hospital in Sao Paulo. The sample consisted of 13 premature infants. We used polysomnograph and unstructured observation for data collection. We analyzed 240 and 1200 minutes corresponding to the periods of the presence and absence of environmental management, respectively. Data were compared in proportion to the total sleep time in the two moments proposed by the study. Results: The total sleep time in periods without environmental management was on average 696.4 (± 112.1) minutes and with management 168.5 (± 27.9) minutes, proportionally premature infant slept an average of 70.2% during periods with no intervention and 58.0% without management (p=0.002). Conclusion: Reducing stimulation and handling of premature infant environment periods was effective to provide greater total sleep time. DESCRIPTORS INTRODUCTIONThe estimate of premature births in Brazil is about 9.8% of the 2,913.160 births registered in 2011 (1) . Due to prematurity, the proportion of premature infants (PI) may require hospitalization in a neonatal unit, which is commonly characterized as in environment that has high sensory stimuli overload for the newborn, additionally, there is a need for frequent management for invasive and painful procedures (2)(3)(4)(5) . The characteristics of the neonatal unit environment and care provided to premature infants according to the institutional routines can reduce the total sleep time leading them to consequent deprivation, which can be constituted in morbidity factor, especially when the gestational age is low and the length of hospital stay is long (2,4,6) . Many studies show that sleep deprivation of premature infants in the neonatal unit can lead to worsening of clinical status and delay hospital discharge, besides that, it could trigger behavioral disorders in adulthood (4,(7)(8) . PI present sleep with polyphasic pattern that are classified into three stages: active, quiet and indeterminate sleep (3,7,(9)(10) . The different stages of sleep are essential for the homeostasis of premature infants, because they establish relations with important physiological and neurological activities (3,9) . In the quiet sleep, decreased basal metabolic rate occurs, which promotes replenishment of energy reserves as well as promote cellular repair, in the active sleep brain activation occurs, which is essential for the structural maturation of the central nervous system (10)(11) . It is noteworthy that the indeterminate sleep cannot be considered as quiet or active, it is characterized as the transition between these two types of sleep patterns (12) . Mitigating possible harmful effects of care provided to hospitalized newborns is one of the actions that should be prioritized by professionals working towards recovery (13) . In this context, the developmental care aims at reduc...

“…A rotina do sono da criança varia de acordo com as suas etapas evolutivas e as necessidades peculiares de cada criança individualmente. Com um padrão polifásico, o RN alterna ciclos de sono e vigília a cada três a quatro horas, sendo esses uniformemente distribuídos entre o dia e a noite (6) . Durante o primeiro mês de vida o RN começa a se adaptar ao ritmo noite-dia.…”

“…Nas crianças nascidas prematuramente, mas clinicamente estáveis e sem comprometimento neurológico, a diferenciação dos estados de sono ativo e quieto pode ser observada a partir da 27ª semana de idade gestacional (6) ; no entanto essas crianças dormem mais e começam a despertar e ficar mais alertas após as 40 semanas de idade gestacional. Os estudos mostram ainda que os bebês pré-termo apresentam períodos de sono tranquilo relativamente mais largos e maior frequência do estado de sono REM (8) .…”

RESUMO Ao longo das últimas décadas a assistência ao recém-nascido vem sofrendo modificações, em conseqüência do surgimento de novas tecnologias e da organização de diferentes ambientes para atender ao neonato. Ao mesmo tempo a exposição desse recém-nascido a essas tecnologias, associada a manipulações excessivas, pode trazer prejuízos importantes ao seu crescimento e desenvolvimento. O presente estudo tem como objetivo identificar na literatura a importância do sono para o crescimento e o desenvolvimento do recém-nascido internado em unidade de terapia intensiva neonatal (UTIN) e oferecer subsídios para a assistência de enfermagem, com base nas formulações da literatura estudada e na experiência profissional das autoras. Trata-se uma pesquisa bibliográfica, com abordagem qualitativa. Foram encontrados 15 artigos publicados em periódicos, nove capítulos de livros, duas tese e um manual que tratavam da temática. Os estudos mostraram que o ambiente da UTIN pode ser altamente estressante e nocivo para o bebê, dificultando sua adaptação ao meio externo e afetando seu crescimento e desenvolvimento neuromotor. Neste sentido, sugerem-se maiores investimentos em estudos dessa temática, bem como na reorganização do trabalho nas UTIN, a partir da conscientização dos profissionais em relação à importância dos cuidados voltados ao desenvolvimento do recém-nascido.
