RESUMO
OBJECTIVE: To evaluate the effectiveness of automated cleaning of 4 mm liposuction cannulas using ultrasonic washer machine, screening for dirt using a cannulate microscope device and the screening of viable strains of Staphylococcus aureus, with microbiological analysis. METHOD: Experimental study with 14 units of 4 mm liposuction cannulas performed at the Central Sterile Services Department and at the Microbiology Laboratory of a Hospital Complex, located in Porto Alegre, RS, Brazil, from October 2018 to April 2019. RESULTS: Of the 14 liposuction cannulas that constituted the sample, 42.9% remained dirty despite automated cleaning, and all of them showed recovery of viable microrganisms in the microbiological laboratory. CONCLUSION: The study showed that it is not possible to ensure the cleaning efficacy of automated cleaning of 4 mm liposuction cannulas, especially due to the conformation of the material with internal spaces with accumulation of dirt.

RESUMEN Objetivo: Evaluar la efectividad de la limpieza automatizada mediante la lavadora ultrasónica de las cánulas de liposucción de 4 mm, mediante el rastreo de la suciedad interna, utilizando el dispositivo de microscopía para canulados y el cribado de cepas viables de Stphylococcus aureus, mediante análisis microbiológico. Método: Estudio experimental realizado con 14 cánulas de liposucción de 4 mm en un Centro de Material y Esterilización y en el laboratorio de microbiología de un hospital de Porto Alegre, Brasil, de octubre de 2018 a abril de 2019. Resultados: De 14 cánulas de liposucción que constituyeron la muestra, el 42,9% permaneció sucio, incluso después de la limpieza automática y todos mostraron recuperación de micoorganismos viables en el laboratorio de mocrobiogía . Conclusión: El estudio mostró que no es posible garantizar la efectividad de la limpieza automática en las cánulas de liposucción de 4 mm, especialmente por la conformación del material con lugares donde se acumula suciedad.
RESUMO Objetivo: Avaliar a eficácia da limpeza automatizada realizada com lavadora ultrassônica de cânulas de aspiração de 4 mm, por meio do rastreamento de sujidade interna feito com aparelho de microscopia para canulados e o rastreamento de cepas viáveis de Staphylococcus aureus, por análise microbiológica. Métodos: Estudo experimental realizado com 14 cânulas de lipoaspiração de 4 mm em um Centro de Material e Esterilização e no laboratório de microbiologia de um hospital de Porto Alegre, Brasil, no período de outubro de 2018 a abril de 2019. Resultados: Das 14 cânulas de lipoaspiração que constituíram a amostra, 42,9% permaneceram com sujidade mesmo após a limpeza automatizada e todas apresentaram recuperação de microrganismos viáveis nos testes do laboratório de microbiologia. Conclusão: O estudo mostrou não ser possível garantir a eficácia da limpeza automatizada nas cânulas de lipoaspiração de 4 mm, em especial devido à conformação do material com locais onde acumula sujidade.
RESUMO
BACKGROUND: Traditional resources, such as bundles, can help experts define essential steps of health product processing to prevent infections. The present study developed bundle content construction and validation criteria for central sterile supply departments (CSSDs). METHODS: The present study employed a Delphi technique modified for content evaluation. Eleven professionals with at least 4 years of experience in sterilization were enlisted. Participants discussed main stages of the process virtually and compiled a list of items based on scientific references justified by law and/or logical reasoning. Agreement, disagreement, and/or suggestions on each step resulted in bundles for a CSSD. Items were then reassessed by experts using a Likert scale with a 90% approval criterion. RESULTS: Six bundles were developed: cleaning, inspection, preparation and packaging, sterilization, and storage resulting from 384 responses and 373 agreements (Interassessor coefficientâ¯=â¯97%). DISCUSSIONS: Items obtained from the criteria assessment received majority agreement from the first document. CONCLUSIONS: Agreement among varying professionals was achieved, and bundles were successfully developed to evaluate the processing of goods in CSSDs.
