Item Avaliação dos testes de resistência em luvas de látex utilizadas em procedimentos odontológicos.(Universidade Brasil, 2024) Beserra, Leidiana Viana; Costa, Mardoqueu Martins daIn clinical practice, professional activities are subject to various occupational risks, among which biological risks stand out for involving pathogens such as bacteria, fungi, protozoa, viruses, and parasites. These agents can invade the body via cutaneous, digestive, and/or respiratory routes, manifesting according to the individual’s immune response. To ensure safe practice and minimize potential contamination, biosafety measures include adopting rigorous protocols and using Personal Protective Equipment such as latex gloves. However, these products can present variations in quality and mechanical resistance among different brands, which compromises the safety of professionals and patients. Therefore, this study aimed to evaluate the quality of latex procedure gloves used in dental clinics, focusing on their mechanical resistance and impermeability. Four brands were analyzed through visual inspection and integrity testing, impermeability testing, and tensile strength tests, which made it possible to determine the maximum force, maximum tension, and elongation before rupture. Dimensional tests revealed no significant difference in glove length among the manufacturers, and width remained consistent, with no notable differences between brands A and D. In the impermeability test, deformation was observed in all brands, with gloves A and B showing no tears, while gloves C had multiple holes and gloves D exhibited leakage near the cuff. Regarding tensile strength, a good stretching capacity before rupture was found, with a maximum force ranging from 12.16 N to 17.94 N (mean of 14.86±2.45 N) and a maximum tension ranging from 38.30 MPa to 56.52 MPa (mean of 46.81±7.76 MPa). Elongation values ranged from 907.04% to 1137.21%, with a mean of 1037.32±89.20%, indicating differences in performance among the analyzed brands and underscoring the importance of carefully selecting products with proven quality control. It is concluded that significant differences exist in terms of impermeability and mechanical resistance of latex gloves, emphasizing the need for a thorough evaluation of these materials to ensure the safety of professionals and patients, thereby helping reduce biological risks in clinical practice and serving as a basis for future research on the quality of this personal protective equipment.Item Manual técnico em biossegurança na paramentação e desparamentação dos equipamentos de proteção individual dos profissionais de saúde que atuam na linha de frente à Covid-19(Universidade Brasil, 2021) Abreu, Regiane Cristina Santos; Navarro, Ricardo Scarparo; Frade-Barros, Amanda FarageThe pandemic triggered by the new Corona virus (SARS-CoV-2), which causes COVID-19, has affected many healthcare professionals worldwide who have been infected, some of them progressing to death. The use of personal protective equipment is ensured as a measure to protect the health and safety of the worker. The preparation of this study aimed to build a technical manual for the attire and undressing of health professionals in the correct execution of the removal and placement of personal protective equipment in patient care with COVID19. The development of the study took place from August 2020 to May 2021. For systematization, the following inclusion criteria were established: article publications and scientific journals from 2015 to 2021 with contextualization on the proposed topic. As exclusion criteria: studies that did not cover the topic in question, articles that were outside the delimited years. Searches were also carried out in the journal Database and CAPES theses database for dissertations and theses on the proposed topic. Six articles were selected, 1 from 2015 and another 15 from 2020. An analysis was made of the materials found, texts and illustrations, allowing the selection of updated contents in the context and illustration, enabling the construction of informative texts. In this study, the “Technical manual on biosafety in the use of PPE for healthcare professionals who work on the front line in combating Covid-19” was developed, aimed at health professionals working on the front line in the fight against COVID-19. This manual will be made available in an e-book allowing the use of health professionals such as doctors, nurses, nutritionists, pharmacists, and physiotherapists.
