“…In the US, it is estimated that flexible endoscopes are used for diagnosis and treatment of gastrointestinal diseases in more than 10 million cases per year (17,20) . Endoscopes are considered semi-critical items because they are designed to come into contact with the mucosa without penetrating the tissue (11) . The safety of endoscopic procedures has been an important issue in the last decade due to the possibility of transmission of microorganisms (6,24) .…”

-Context -The endoscopic procedure safety depends on the use of an adequately reprocessed device which quality is related to each of its operational steps. Objective -To characterize the reprocessing of endoscopes using glutaraldehyde in endoscopy services Methods -Study was conducted by observing the reprocessing of 60 endoscopes from 20 medical practices of the municipality of Goiânia, GO, central area of Brazil. Results -This study showed failure in all reprocessing steps. The pre-washing was performed in 24 (40.0%) of the endoscope. In the cleaning steps, was identify the improper use of enzymatic detergent, and in 27 (45.0%) cases, the brushing of internal channels was not performed. All 60 endoscopes were submitted to this disinfectant. However, for 33 (55.0%) of the cases the internal channels was not filled. The total immersion of endoscope in the glutaraldehyde was not performed in 39 (65.0%) cases. The recommended minimum total immersion time for exposure to 2% glutaraldehyde solution was followed only for 12 (20.0%) endoscopes. There was no filter for water treatment used in the rinse of most endoscopes 54 (90.0%) and to dry the internal channels only 6 (10.0%) of them used compressed air. Adequate storing conditions were identified. Conclusion -Considering the particularities of the endoscope and its reprocessing, it is imperative to establish protocols to ensure the quality of the disinfection and the prevention of cross-contamination.

“…A principal razão para isso é a falta de estudos adequados sobre esse assunto. 16 De acordo com os resultados desta revisão sistemática verifi cou-se uma grande variedade nos estudos quanto aos artigos, tipos de investigação, métodos de análises empregados e procedimentos de reprocessamento, o que contribuiu para resultados diversos sobre esta pesquisa. É fundamental considerar todos os procedimentos envolvidos no reprocessamento e nas análises para sua qualifi cação.…”

DESCRITORES Esterilização Infecção hospitalar Equipamentos cirúrgicos Saúde pública KEYWORDS Sterilization Cross infection Surgical Equipment Public HealthJustifi cativa e Objetivos: Os instrumentos cirúrgicos são amplamente reprocessados, principalmente em países em desenvolvimento, onde os custos da utilização desses insumos são altos. A literatura científi ca aponta a ausência de processos validados de limpeza e esterilização. O objetivo do trabalho foi avaliar por meio de uma revisão bibliográfi ca evidências que apoiem ou não a prática do reprocessamento e reutilização de instrumentos médico-hospitalares, a princípio de uso único. Método:Foram selecionados 27 artigos em revistas indexadas nas bases de dados LILACS, Pubmed e Medline, e pesquisas no Science Direct publicados sob os unitermos "esterilização", "artigos de uso único", "infecção hospitalar" e "aparelhos cirúrgicos" nos idiomas inglês e português. Foram excluídos os artigos que não contemplavam a temática do estudo. Resultados: Verifi cou-se grande variedade dos instrumentos estudados e formas de reprocessamento. A maioria dos artigos evidencia uma inefi cácia da esterilização, identifi cando microrganismos ao fi nal do processo. Conclusão: Baseado no conhecimento atual é importante considerar cada caso validando protocolos de reprocessamento e reuso dos materiais cirúrgicos com base em conhecimento científi co. A partir da análise dos artigos em estudo, conclui-se que essa prática não pode ser realizada indiscriminadamente. Backgound and Objectives:Surgical instruments are widely reprocessed, mainly in developing countries, where the cost of using these materials is high. Scientifi c literature indicates the absence of validated cleaning and sterilization processes. The study aimed at evaluating, through a literature review, the evidence to support or not the practice of reprocessing and reuse of originally single-use, medical-hospital materials. Methods: A total of 27 articles in English and Portuguese were selected from journals indexed in the LILACS, Pubmed and Medline databases, as well as studies published in ScienceDirect website using the following key words: sterilization, single-use articles, hospital infection and surgical instruments. Articles that did not fi t the study subject were excluded. Results: There was a great variety of studied instruments and reprocessing methods. Most articles emphasize the sterilization ineffectiveness, identifying microorganisms at the end of the process. Conclusion: Based on the current knowledge, it is important to consider each case validating surgical materials reprocessing and reuse protocols based on scientifi c knowledge. Based on the analysis of the study articles, we concluded that this practice cannot be performed indiscriminately.

Marked bactericidal activity of the electrolyzed acid water (EAW) and its less undesirable effects on biological tissues and the environment has been successfully utilized in dental practice. A review of literature reveals that not many studies have been performed to determine the disinfection effect of EAW on heat cured acrylic denture bases. The objective of the study is to determine the efficacy of EAW in disinfecting heat cured acrylic resin specimens as compared to the efficacy of disinfecting the specimens using 2% glutaraldehyde. Heat cured acrylic resin plates were immersed in Bacteria suspensions of Staphylococcus aureus and later disinfected using EAW which was produced using a custom made electrolyzing apparatus and 2% glutaraldehyde for different time intervals. The numbers of surviving bacteria were counted. As the control, the bacteria attached on the specimens were counted with out any disinfection treatment. The results obtained were statistically analyzed using ANOVA and post-hoc test. The disinfection potential of 2% glutaraldehyde was better than EAW when the specimens were disinfected for 1 and 3 min. Where as when the disinfection time was increased to 5 min there was no difference between EAW and 2% glutaraldehyde. However considering that the disinfecting time can be easily extended to 5 min, EAW can be effectively used for disinfecting the acrylic denture.
