Objective: To evaluate the disinfectant effectiveness of alcohol 70% (w/v) using friction, without previous cleaning, on work surfaces, as a concurrent disinfecting procedure in Health Services.Method: An experimental, randomized and single-blinded laboratory study was undertaken.The samples were enamelled surfaces, intentionally contaminated with Serratia marcescens microorganisms ATCC 14756 10 6 CFU/mL with 10% of human saliva added, and were submitted to the procedure of disinfection WITHOUT previous cleaning. The results were compared to disinfection preceded by cleaning. Results: There was a reduction of six logarithms of the initial microbial population, equal in the groups WITH and WITHOUT previous cleaning (p=0.440) and a residual microbial load ≤ 10 2 CFU. Conclusion: The research demonstrated the acceptability of the practice evaluated, bringing an important response to the area of health, in particular to Nursing, which most undertakes procedures of concurrent cleaning /disinfecting of these work surfaces.

OBJECTIVE: this study aimed to evaluate the efficacy of hand hygiene performed with two different soap formulations: 0.3% Melaleuca alternifolia essential oil versus 0.5% triclosan, and to compare them with two reference hygiene procedures: the official methodology procedure (soft soap) versus the draft version of the procedure (soft soap + propan-2-ol). METHOD: using the European EN 1499 method, logarithmic reduction factors were determined for the number of colony forming units of Escherichia coli K12 before and after hand hygiene of 15 volunteer subjects, and compared using the one-tailed Wilcoxon test. RESULTS: referring to the soft soap, there was no difference between the performance of soap with 0.3% M. alternifolia and soap containing 0.5% triclosan. The soft soap + propan-2-ol proved to be more effective than the other hand hygiene procedures. CONCLUSION: studies to verify the therapeutic efficacy of essential oil in hand hygiene can improve adherence to this practice.

RESUMoSão diversificadas as recomendações referentes à temperatura (T°) e umidade relativa do ar (UR) no armazenamento de materiais esterilizados em Centrais de Material e Esterilização (CME), sem que essas recomendações estejam embasadas em referenciais teóricos ou experimentos. A prá-tica mostra dificuldades em controlar esses parâmetros, suscitando dúvidas quanto ao risco para a manutenção da esterilidade dos materiais. Este artigo propôs, por meio de uma revisão bibliográfica integrativa, identificar e analisar as recomendações referentes à T° e UR indicadas para o setor de guarda dos materiais na CME. Não foi encontrada literatura que justifique tais recomendações. Foram incluídas sete publicações que analisaram as variáveis T° e UR da área de armazenagem como fatores que podem afetar a manutenção do material esterilizado, e apresentaram resultados contraditórios quanto à interferência desses fatores na manutenção da esterilidade dos materiais. ABSTRACTThe recommendations for temperature (T°) and relative humidity (RU) for the storage of sterilized materials in Sterilization Central Supply (SCS) vary according to different sources, and are not based on theoretical frameworks or experiments. The practice shows difficulties in controlling these parameters, leading to doubts regarding the maintenance of the sterility of these materials. This article proposed, through a literature review, to identify and analyze the recommendations for T° and RU for the sterile storage area. We did not find any literature that justifies the referred recommendations. Seven articles were included which analyzed the variables T° and RU in the storage area as factors that could affect the sterility of the materials, and showed contradictory results regarding these factors' interference in maintaining the sterility of the materials.
