ABSTRACT
BACKGROUD: Endoscopes are routinely used in hospitals and clinics of the world and they can be potential sources of cross-infection when the decontamination process is unsuitable AIM: The routines of flexible endoscope (bronchoscopes, esophagogastroduodenoscopes and colonoscopes) disinfection procedures used in two Brazilian university hospitals were evaluated during a 3-year period METHODS: Aleatory samples from internal channels of endoscopes were collected after patient examination and after cleaning/disinfection procedures RESULTS: A contamination >3 log10 was achieved in samples recovered from endoscopes after patient examination. These samples yielded gram-negative bacilli (n = 142: 56 percent), gram-positive cocci (n = 43: 17 percent), yeast cells (n = 43: 17 percent), and gram-positive bacilli (n = 26: 10 percent). Approximately, 72 out of 149 samples (48.32 percent) collected after undergoing the cleaning and disinfection procedures disclosed gram-negative bacilli (n = 55: 61 percent), gram-positive cocci (n = 21: 23 percent), gram-positive bacilli (n = 8: 9 percent) and yeast cells (n = 6: 7 percent). Esophagogastroduodenoscopes and colonoscopes were the most frequently contaminated devices. Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Enterobacter spp, Serratia marcescens, Proteus mirabilis, Citrobacter freundii, Staphylococcus aureus, Staphylococcus coagulase negative, Micrococcus luteus, Candida albicans, C. tropicalis, C. glabrata, C. guilliermondii, Bacillus spp and Corynebacterium spp were predominantly identified CONCLUSION: Inappropriate cleaning and low times of disinfection were respectively the major factors associated with the presence of microorganisms in colonoscopes and esophagogastroduodenoscopes. By analyzing the identified germs, hospital disinfection was considered of either intermediate or poor level. After this investigation, both university centers improved their previous protocols for...
RESUMO
RACIONAL: Endoscópios são rotineiramente utilizados em hospitais e clínicas e podem ser fontes potenciais de infecção cruzada quando a descontaminação é inadequada OBJETIVO: As rotinas de descontaminação dos endoscópios flexíveis (broncoscópios, gastrocópios e colonoscópios) realizadas em dois hospitais universitários do Brasil foram avaliadas durante 3 anos MATERIAL E MÉTODOS: Amostras aleatórias foram coletadas dos canais internos dos endoscópios, depois que o aparelho era utilizado nos pacientes e após o processo de desinfecção RESULTADOS: Contaminação superior a 103 foi verificada em amostras coletadas após o exame endoscópico, sendo isolado bacilos gram-negativos (n = 142: 56 por cento), cocos gram-positivos (n = 43: 17 por cento), leveduras (n = 43: 17 por cento) e bacilos gram-positivos (n = 26: 10 por cento). Em 72 das 149 amostras coletadas após procedimentos de limpeza e desinfecção, detectou-se bacilos gram-negativos (n = 55: 61 por cento), cocos gram-positivos (n = 21: 23 por cento), bacilos gram-positivos (n = 8: 9 por cento) e leveduras (n = 6: 7 por cento). Gastroscópios e colonoscópios eram os aparelhos com maior freqüência e taxa de contaminação. Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Enterobacter spp, Serratia marcescens, Proteus mirabilis, Citrobacter freundii, Staphylococcus aureus, Staphylococcus coagulase negative, Micrococcus luteus, Candida albicans, C. tropicalis, C. glabrata, C. guilliermondii, Bacillus spp and Corynebacterium spp foram os mais identificados CONCLUSÃO: A limpeza inapropriada e curto período de tempo de desinfecção eram, respectivamente, os maiores fatores associados com a presença de microrganismos em gastroscópios e colonoscópios. De acordo com os organismos isolados, considera-se que a desinfecção nos hospitais era de nível baixo a intermediário. Após a investigação, os centros de endoscopia adequaram seus protocolos, sanando os problemas verificados nos procedimentos...
