No. of bitstreams: 0 / O sinal de fluxo cutâneo obtido via fluxometria Laser Doppler (SFLD) tem flutuações de baixas frequências que estão relacionadas a mecanismos de controle do fluxo microvascular. Análises espectrais, via transformada de Fourier e transformada de wavelet, têm sido usadas para correlacionar as flutuações de SFLD com os seguintes mecanismos de controle de fluxo: metabólico, metabólico NO-dependente, neurogênico e miogênico, nos respectivos intervalos de frequência 0,005-0,0095 Hz, 0,0095-0,02 Hz, 0,02-0,05 Hz e 0,05-0,15 Hz. A potência do sinal, em cada intervalo de frequência, geralmente é usada como uma medida da atividade do mecanismo de controle microvascular relacionado. Uma vez que os métodos usados de análise são espectrais, as características das flutuações do SFLD, em cada intervalo de frequência, no domínio do tempo são desconhecidas. Como consequência, há ausência de critérios objetivos para medir adequadamente, em cada intervalo de frequência, os parâmetros hemodinâmicos relacionados. O objetivo deste trabalho foi caracterizar e quantificar flutuações temporais, espaciais e espaço-temporais do SFLD em cada faixa de frequência, usando um método no domínio do tempo. Os fluxos basais (320C) e termicamente estimulados à (420C) das regiões volares de antebraços de 20 voluntários saudáveis foram coletados em duas regiões próximas e analisados. As análises dos dados obtidos indicam que janelas temporais pequenas (1 minuto) são aceitáveis para a quantificação do fluxo médio, e que janelas temporais maiores são necessários para quantificar as flutuações de fluxo. A análise espaço-temporal revelou uma forte correlação entre sinais (em todas as bandas, exceto na banda B5) das duas regiões investigadas, durante longos intervalos de tempo, quando as duas regiões estudadas foram termicamente estimuladas, e menor variabilidade intragrupo quando comparada à obtida para os valores médios das flutuações, sugerindo que o intervalo de tempo de correlação é um parâmetro promissor para estudar mecanismos de controle do fluxo microvascular. / Tese (Doutoramento) / IPEN/D / Instituto de Pesquisas Energéticas e Nucleares - IPEN-CNEN/SP

O cuidado com feridas crônicas faz parte do cotidiano do enfermeiro, o que torna relevante o conhecimento de sua experiência e expectativas em relação ao tratamento de pessoas com úlcera venosa crônica (UVC). Este estudo, com abordagem da Fenomenologia Social de Alfred Schutz, teve como objetivo compreender a experiência e as expectativas do enfermeiro em relação ao cuidado à mulher com úlcera venosa crônica na Atenção Primária à Saúde. Foi realizado com sete enfermeiras que atuam em Unidades de Atenção Primária à Saúde de Juiz de Fora, Minas Gerais. A obtenção dos depoimentos ocorreu em janeiro de 2012, e foi utilizada a entrevista fenomenológica, com as seguintes questões norteadoras: como é para você cuidar de mulheres com UVC? Fale-me das suas expectativas quando cuida de uma mulher com UVC. A análise compreensiva permitiu tipificar a enfermeira como aquela profissional que identifica as dificuldades da mulher para realizar seu autocuidado, considerando as questões inerentes a seu cotidiano, a baixa autoestima e a falta de suporte da família para o prosseguimento do tratamento. Ela percebe limitações na terapêutica, que é prejudicada por valores e crenças relacionadas à ferida, desmotivação da mulher e a própria frustração, principalmente em face da recidiva da lesão. Refere-se também à falta de insumos e tecnologia, de trabalho interdisciplinar e capacitação da equipe de enfermagem como fatores limitantes para o tratamento. Tem como expectativa a adesão da mulher ao tratamento da UVC e realça a necessidade do cuidado contínuo, as orientações para o autocuidado e a padronização de condutas no tratamento de feridas para evitar as recidivas da lesão, propiciando-se à mulher obter maior qualidade de vida. Evidenciou-se que os limites e as possibilidades que permeiam o cuidado se relacionam a diversos sujeitos, instituições e políticas de saúde nele envolvidos. Espera-se que esta pesquisa possibilite reflexões e ações no âmbito assistencial, do ensino e da pesquisa no que tange ao cuidado à mulher com UVC. Estas devem fundamentar a aplicação do conhecimento deste estudo nos referidos âmbitos, valorizando os diversos aspectos objetivos e subjetivos entremeados no cuidado a essa mulher. / The care of chronic wounds is part of daily nursing, being relevant to know your experience and expectations regarding the treatment of people with chronic venous ulcers (CVU). A study used the approach of Social Phenomenology by Alfred Schutz to understand the experiences and expectations of nurses who cared for women with Chronic Venous Leg Ulcers (CVLU) in primary health care. This study was conducted with seven nurses who were working in Primary Health Care units, Juiz de Fora, Minas Gerais. The taking of statements took place in January 2012, utilizing the phenomenological interview approach, asking the following questions: How do you take care of women with CVLU? What are your expectations when caring for a woman with CVLU? The comprehensive analysis resulted in classifying the professional nurse as one who identifies the difficulties of women to perform self-care, considering the issues inherent in their daily life, low self-esteem and lack of family support for the continuation of treatment. Perceived limitations in therapy are affected by values and beliefs related to the condition and the woman\'s and nurses frustration, mainly due to reoccurrence of the wounds. The study also refers to the lack of inputs and technology, interdisciplinary work and training of nursing staff as limiting factors for treatment. The expectation is that the treatment of CVLU, underlining the necessity of continuous care, self care guidelines and standardization of ducts to treat wounds and preventing recurrences of the injury, thereby allows women to achieve a better quality of life. It was evident that the limits and possibilities that permeate the care of this disease are due to various situations, including institutions and health policies related to it. It is hoped that this research allows will result in reflections and actions in health care, education and research regarding the care of women with CVLU. This research should support the application of knowledge in these areas of study, highlighting the various objective and subjective aspects woven into the care of woman.
