Resumo: | A autora apresenta protocolo de descontaminação de máscaras de filtro N95 por meio da irradiação ultravioleta de ondas-curtas (UV-C), assim como, resultados da testagem microbiológica de validação do dispositivo UV-C e de pesquisa qualitativa sobre a adesão de profissionais do Hospital Universitário João de Barros Barreto, do Complexo Hospitalar Universitário da Universidade Federal do Pará (HUJBB), ao referido protocolo. Os testes microbiológicos demonstraram a eficácia do protocolo de descontaminação, pois não houve crescimento bacteriano em meios de cultura inoculados com esfregaços de máscaras usadas no hospital e descontaminadas no dispositivo UV-C, o que comprovou a eficiência germicida da irradiação UV-C. Os resultados da pesquisa qualitativa apontam para adesão dos profissionais da enfermagem à prática de descontaminação das máscaras, reconhecendo a praticidade e a contribuição do protocolo para a biossegurança e segurança ocupacional. Como parte do mesmo protocolo, é apresentada uma alternativa de embalagem para armazenamento das máscaras nos intervalos de uso das máscaras N95, considerando sua reutilização segura. O protocolo apresenta, ainda, como vantagens: o baixo custo e a praticidade de uso, além de contribuir para a redução do lixo infectante. |
Abstract: | he author presents a protocol for decontamination of N95 filter masks by means of short wave ultraviolet irradiation (UV-C), as well as the results of the microbiological validation testing of the UV-C device and qualitative research on the adherence of professionals from the João de Barros Barreto University Hospital, of the University Hospital Complex of the Federal University of Pará (HUJBB) to the aforementioned protocol. The microbiological tests demonstrated the efficacy of the decontamination protocol, as there was no bacterial growth in culture media inoculated with swabs of masks used in the hospital and decontaminated in the UV-C device, which proved the germicidal efficiency of UV-C irradiation. The results of the qualitative research point to the adherence of nursing professionals to the practice of mask decontamination, recognizing the practicality and contribution of the protocol to biosafety and occupational safety. As part of the same protocol, an alternative packaging for storing masks in the intervals of use of N95 masks is presented, considering their safe reuse. The protocol also has the following advantages: low cost and practicality of use, in addition to contributing to the reduction of infectious waste. Descriptors: Decontamination. Ultraviolet Rays.
