The present study aims at evaluating the correlation between the free radical formation and the healing action of lower limbs' ulcers in a randomized controlled trial with the use of an adhesive derived from natural latex associated with a light-emitting diode (LED) circuit. The sample consists of 15 participants with lower limb lesions divided into three groups: group 1 case (5 participants) received the proposed dressing system adhesive of the natural latex associated with the LED circuit; group 2 control (5 participants) received the dressings at home performed by nurses according to and established by the clinic of wounds (treated with calcium alginate or silver foam); and group 3 (5 participants) also received the dressing in their homes with the use of the dressing adhesive derived from the natural latex associated with the LED circuit. The collected data were analyzed qualitatively and quantitatively by electron paramagnetic resonance for determination of free radical formation. Kruskal-Wallis statistical test was used to evaluate the effect of treatment on the lower limb's ulcer cicatrization process and its correlation with free radical. The results obtained corroborated the hypothesis about the reduction of the quantity of these molecules in the end of treatment related to the healing wound.
Objetivo:caracterizar o Risco de Glicemia Instável de pacientes com feridas de membros inferiores em uso látex associado ao LED. Método: Estudo de coorte prospectivo com amostra n=15. Dividi-dos em três grupos Grupo 1 curativo com látex e LED; Grupo 2 carvão ativado; e Grupo 3 realiza-vam autocurativo com látex e LED e identificação do Risco de glicemia instável. Análise de dados realizada pelo software SPSS®. Resultados: Os participantes 60% homens, idade 59,93±10,88 anos, fatores de Risco de glicemia instável: atividade física diária menor que o recomendado; co-nhecimento insuficiente do controle da doença, em todos os grupos; condição de saúde comprome-tida grupos I e III; controle insuficiente do diabetes grupo I; falta de adesão ao plano de controle do diabetes início ao fim, exceto pelo grupo II. Ocorreu redução das feridas em todos os grupos e me-lhor cicatrização no grupo III. Conclusão: A feridas maiores estavam no grupo I e ocorreu redução das feridas todos os grupos. Os principais fatores de risco de glicemia instável atividade física diária menor que o recomendado no início e final; condição de saúde comprometida grupos I e III; conhe-cimento insuficiente do controle da doença em todos os grupos.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
