Active cycle breathing techniques como técnica de higiene brônquica na asma: estudo piloto

RESUMO: Relevância e Objectivos: O objectivo deste estudo consistiu em verificar a eficácia e segurança de uma técnica de higiene brônquica – Active Cycle breathing technique (ACBT), na remoção de secreções e desinsuflação em crianças asmáticas. É uma técnica recente, que ainda não foi estudada nesta população. Metodologia: A amostra foi constituída por um total de 14 crianças, com idades compreendidas entre os 6 e 18 anos, com o diagnóstico de asma. Foi dividida em dois grupos: grupo de controlo, constituído por asmáticos estáveis e grupo experimental constituído por asmáticos pós-crise. Ambos receberam o mesmo tratamento, que consistiu numa única sessão de ACBT. Realizaram um exame da função respiratória (variáveis FEV1, PEF, MEF75%, RV e FRC) antes e após a aplicação da técnica. Mediu-se a Saturação de O2 antes, a meio e no fim da aplicação da técnica. Por último, pesaram-se as secreções recolhidas durante a sessão de tratamento. Resultados: Como resultados, quando omparamos o antes e após aplicação do ACBT, obtivemos diferenças significativas no RV (p <0,05) e FRC (p <0,05); muito significativa na Sa02 (p <0,01) e peso de secreções, nos asmáticos pós crise. Ocorreu uma melhoria significativa da saturação (p <0,05) em asmáticos estáveis, não havendo secreções. Não houve efeitos adversos nem broncoespasmo em ambos os grupos.Conclusão: O ACBT é uma técnica que promove a remoção de secreções e diminuição da insuflação na população de asmáticos.--------------------ABSTRACT:Relevance and Goals: the goal of this study was to verify the efficiency and security of a bronchial hygienic technique - Active Cycle Breathing Technique (ACBT) – in the obstruction and insufflation of asthmatic children. This is a new technique that has not yet been studied in this population. Procedures: The subjects were 14 children aged between 6 and 18 years old with asthma diagnosis. They were divided in two groups: the control group with stable asthmatics and the experimental group with post-crisis asthmatics. Both received the same treatment that was a single session of ACBT. They made a lung function test before and after the application of the technique (variables FEV1, PEF, MEF75%, RV and FRC). The level of O2 saturation was measured before, during and after the procedure. In the end, the secretions collected during the treatment were weighted. Results: We observed a significant difference on RV (p ˂0,05), FRC (p ˂0,05), Sa02 (p ˂0,01) and in the weight of the secretions in the post-crisis asthmatics after ACBT. There was a significant improvement of saturation (p ˂0,05) only in the stable asthmatics. There were no adverse effects or bronchospasm in both groups.

Spore differentiation in relation to the infectious cycle of the enteric pathogen Clostridium difficile

Clostridium difficile is a gram positive, spore former, anaerobic bacterium that is able to cause infection and disease, with symptoms ranging from mild diarrhea to pseudomembranous colitis, toxic megacolon, sepsis and death. In the last decade new strains have emerged that caused outbreaks of increased disease severity and higher recurrence, morbidity and mortality rates, and C. difficile is now considered both a main nosocomial pathogen associated with antibiotic therapy as well as a major concern in the community.(...)
