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.

This experimental, comparative, laboratory study evaluated the effectiveness of the sterilization of single-use laparoscopic instruments -SULIs (grasper, dissector, scissors, Veress needle and electrosurgical probe system), after contamination-challenge with bacterial spores and sheep blood, and compared the results of the sterilization tests with those of the equivalent reusable instruments. The cleaning methods used were; ultrasonic washer with pulsatile water jet and enzymatic detergent, manual cleaning, cleaning with pressurized water and rinsing. The SULIs were sterilized with ethylene oxide and the reusable instruments in an autoclave. Sterility tests showed 100% negative results for recovery of contaminate microorganisms in both groups. It was concluded that, regarding the sterilization, that it is possible to reprocess SULIs. Evaluación de la esterilidad del instrumental laparoscópico descartable reprocesadoSe trata de un estudio, experimental, de laboratorio y comparativo, que evaluó la eficacia de la esterilidad de los instrumentos laparoscópicos de uso único(ILUU): grasper, disector, tijera, aguja de Veres y el sistema de sonda electroquirúrgica, después de "contaminación desafío" con esporas bacterianas y sangre de carnero; los resultados de las pruebas de esterilidad fueron comparados con los de los instrumentos equivalentes "permanentes". Para efectuar la limpieza se utilizó: lavadora ultrasónica con chorro pulsante y detergente enzimático, limpieza manual, agua bajo presión y enjuague.Los ILUU fueron esterilizados con óxido de etileno, los instrumentos "permanentes" en autoclave. Las pruebas de esterilidad mostraron resultados 100% negativos para la recuperación de los microorganismos contaminantes en los dos grupos. Se concluye que, en relación al alcance de la esterilidad, es posible reprocesar los ILUU.

The present study evaluated the efficacy of disposable surgical masks as a microbial barrier with 95% of Bacteria Filtration Efficacy (BFE) according to the wearing time (1, 2, 4 and 6 hours). The masks showed a decrease in efficacy after a 4-hour wearing time.

Objective: to assess the efficacy and the effectiveness of 60-80% alcohol (v/v) in the disinfection of semi-critical materials which were either previously cleaned or not. Method: studies obtained from BIREME, IBECS, MEDLINE, ScIELO, PubMed, Ask Medline web portals, and references from other studies. Criteria were created to assess the methodological quality of articles. Out of the 906 studies found, 14 have been included. Results: after materials were disinfected with alcohol, microorganisms were detected in 104/282 (36.9%) effectiveness tests and in 23/92 (25.0%) efficacy tests that were conducted. In the field studies, disinfection was not achieved for 74/218 (33.9%) of the products that were submitted to previous cleaning and for 30/64 (46.9%) of the ones which were not submitted to previous cleaning. In the experimental studies, alcohol disinfection was not efficacy in 11/30 (36.7%) and 12/62 (19.4%) of products, respectively. The studies were not found to have followed standardized methods. Conclusion: disinfection of semi-critical products with alcohol 70% - or in an approximate concentration - cannot be recommended to all health care products in an unrestricted way. However, according to the type of semi-critical product, disinfection can be attained with or without previous cleaning.

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.

Este estudo teve como objetivo comparar a eficácia de preparações alcoó-licas com os produtos tradicionais na antissepsia cirúrgica das mãos por meio de uma revisão sistemática da literatura. Foram considerados estudos primários ou secundários, tendo como desfecho a contagem microbiana das mãos ou taxas de infecções do sítio cirúrgico. A busca foi realizada no Portal BVS, PubMed, Ask e MEDLINE. Foram selecionados 25 estudos (2 revisões sistemáticas, 19 experimentais e 4 de corte). As preparações alcoólicas tiveram uma redução microbiana igual e/ou maior aos produtos tradicionais em 17 estudos e inferior em 4; as taxas de infecções do sítio cirúrgico foram similares. Portanto, existem evidências científicas que suportam a segurança das preparações alcoólicas para antissepsia cirúrgica das mãos. dEScRitoRES Antissepsia Cirurgia geral Lavagem de mãos Controle de infecções Enfermagem de Centro CirúrgicoA systematic review of surgical hand antisepsis using an alcohol preparation compared to traditional products * Original article AbStRActSurgical hand antisepsis aims at preventing surgical site infections, an important cause of postoperative morbidity and mortality and escalating hospital costs. The objectives of this study were to compare the efficacy of alcohol preparations with traditional surgical hand antisepsis products by means of a systematic review of the literature. Primary and secondary studies were included, considering the microbial count or surgical site infection rates as outcomes. The search was performed on the BVS Portal, PubMed, Ask and MEDLINE. Twentyfive studies were selected (two systematic reviews, nineteen experimental and four cohort studies). The alcohol preparations promoted a microbial reduction equal to and/or greater than traditional products in 17 studies, and a lesser reduction in four studies; similar surgical site infection rates were identified. Therefore, there is scientific evidence that support the safety of alcohol preparations for surgical hand antisepsis.
