Aim： Was to analyze the effectiveness of tubes decontamination made by disinfectant substances used in a clinical setting and to identify the microorganisms found on their surface. Materials and Methods： 14 anesthetic tubes were collected from dental clinic, on 5 groups. 01 plastic and 01 glass tubes that were not submitted to any disinfection process composed the control group and they had been sown in Agar Blood. Experimental groups underwent immersion and fixation with the proposed chemicals for 1 minute, laminar flow hood was used to seed it in Agar Blood and then it was transferred to incubator for 24 hours at 37℃. Tests were used to identify the main Gram positive pathogenic genera. Gram-negative pathogenic colonies isolated were seeded in biochemical means of identification. Results： It was possible to identify the presence of Staphylococcus coagulase negative, Staphylococcus aureus, Streptococcus viridans, Staphylococcus saprophyticus, Escherichia coli and Acinetobacter spp, as well as the effectiveness of chemical solutions proposed in this study. Conclusions： All chemical solutions proposed in this study were effective for the surface disinfection process of anesthetic tubes.展开更多
