Eficácia da biomembrana de látex natural incorporada com extrato de Stryphnodendron barbatimam mart na cicatrização de úlceras cutâneas /

Silva, Rosângela Gonçalves da. January 2015 (has links)
Orientador: Rondinelli Donizetti Herculano / Banca: Marco Andrey Cipriani Frade / Banca: Aldo Eloizo Job / Resumo: A biomembrana de látex da seringueira (Hevea brasiliensis) tem sido utilizada como curativo para úlceras cutâneas e os estudos de sua utilização como sistema de liberação prolongada para carrear compostos bioativos capazes de acelerar e estimular o processo de cicatrização tecidual estão em ascendência. A cicatrização lenta caracteriza a cronicidade da lesão e se dá na ocorrência da ausência ou insuficiência do fechamento da ferida, excedendo o período fisiológico da cicatrização de 2 a 3 semanas. As razões para esta alteração são os distúrbios locais ou sistêmicos (DEALEY, 2008). O objetivo deste estudo foi avaliar a eficácia e segurança do tratamento das úlceras crônicas com a utilização da biomembrana de látex natural da seringueira Hevea brasiliensis incorporada com extrato de Stryphnodendron barbatimam Mart (barbatimão). Foram selecionados 45 pacientes com úlceras crônicas de diferentes etiologias com idade entre 35 e 90 anos, cadastrados no Sistema Único de Saúde (SUS) e em sua respectiva unidade de atendimento. Estes sujeitos foram divididos em três grupos de 15 indivíduos cada e foram tratados por um período mínimo de 30 dias que se iniciou em abril de 2014, sendo apresentados como: grupo teste G1- Biomembrana de látex natural incorporada com extrato de barbatimão, tendo ocorrido 1 exclusão; grupo controle G2- Biomembrana de látex natural, tendo ocorrido 7 exclusões; e grupo controle G3- extrato de barbatimão, tendo ocorrido 10 exclusões. Além dos curativos, foram realizadas coleta de amostras para semeadura em meios seletivos, demonstrando que mesmo com a presença de microrganismos não houve interferência na cicatrização. Os curativos realizados com biomembrana incorporada apresentaram melhores resultados na cicatrização, além de controle e até redução da colonização microrgânica ...

The slow healing features the chronicity of the wound and it occurs in the wound closure absence or failure, exceeding the physiological healing period of 2 to 3 weeks. The reasons for such change are local and systemic disorders. This study was carried out to assess the effectiveness and safety of chronic ulcer treatment by using the natural latex biomembrane derived from the Hevea brasiliensis rubber tree incorporated with the Stryphnodendron barbatimam Mart (barbatimão) extract. In the research 45 patients were selected, they were suffering from chronic ulcers of different etiologies, age between 35 and 90, registered in the National Health System (SUS) and under the care of their respective health care unit. Those subjects were divided into three groups comprising 15 patients each who were treated along a minimum period of 30 days which began in April 2014, and they were characterized as G1 test group- natural latex biomembrane combined with barbatimão extract, with 1 exclusion; G2- natural latex biomenbrane, with 7 exclusions; and G3- barbatimão extract, with 10 exclusions. Besides the dressings, sample collections were carried out for sowing in selective environments, showing that despite the presence of microorganisms there was no interference in wound healing. The dressings made from combined biomembrane yielded better results not only in wound healing, but also in controlling and reducing microorganism colonies, in comparison with the other control groups. The results found surely provide subsidies for future ... (Complete abstract click electronic access below) / Mestre
