“…Pseudomonas is able to form biofilms, and these biofilms are extremely difficult to remove from plumbing, AERs, and endoscope channels (2,89). Serotype 10 of P. aeruginosa predominates in the published reports of Pseudomonas transmission (22,23,53,73,90,91). It is possible that slime production by P. aeruginosa serotype 10 in a biofilm can form a barrier to antibiotics and disinfectants and lead to antibacterial resistance, but no explanation was offered as to why specifically this serotype was isolated.…”

“…Many outbreaks of P. aeruginosa infection after GI endoscopy and bronchoscopy have been associated with inadequate cleaning and the use of inappropriate intermediate-level and low-level disinfectants (29,62,64,73,80,90,(95)(96)(97)(98), contaminated endoscope water bottles and the water supply to the endoscope (29,65,90,99,100), and drying of endoscope channels with no flushing with 70% ethanol after disinfection (22,30,70,(73)(74)(75) or lack of a drying procedure (26,64) (Tables 2 to 5). Two recent outbreaks of multidrug-resistant P. aeruginosa post-ERCP infections have been related to the remaining contamination of the endoscope despite accurate reprocessing followed by negative surveillance endoscope cultures (2,101).…”

SUMMARY Flexible endoscopy is a widely used diagnostic and therapeutic procedure. Contaminated endoscopes are the medical devices frequently associated with outbreaks of health care-associated infections. Accurate reprocessing of flexible endoscopes involves cleaning and high-level disinfection followed by rinsing and drying before storage. Most contemporary flexible endoscopes cannot be heat sterilized and are designed with multiple channels, which are difficult to clean and disinfect. The ability of bacteria to form biofilms on the inner channel surfaces can contribute to failure of the decontamination process. Implementation of microbiological surveillance of endoscope reprocessing is appropriate to detect early colonization and biofilm formation in the endoscope and to prevent contamination and infection in patients after endoscopic procedures. This review presents an overview of the infections and cross-contaminations related to flexible gastrointestinal endoscopy and bronchoscopy and illustrates the impact of biofilm on endoscope reprocessing and postendoscopic infection.

“…Rubbo et al (52) relataram que 99,99% de esporos de Bacillus anthracis e Clostridium tetani foram eliminados com o tempo de 15 e 30 minutos, respectivamente. Muitos fabricantes, no entanto, têm recomendado de 10 a 12 horas para a esterilização com o glutaraldeído, no caso de haver fatores adversos, como esporos resistentes ou rediluição da solução germicida ou, ainda, inativação desta por maté-ria orgânica (53) . Na pesquisa de BAAR, deste estudo, não houve resultados positivos.…”

“…Leers (27) , em 1980, recomenda tratamento com glutaraldeído a 2% por 10 a 30 minutos para desinfecção de endoscópios fibroópticos, precedido de adequada limpeza. Um grande número de trabalhos, também, demonstrou a atividade antiviral efetiva do glutaraldeído a 2%, mesmo em presença de matéria orgânica, embora esta a lentifique (53,60) . A matéria orgânica, inevitável e associada ao constante uso da solução, ajuda a mudar seu potencial germicida.…”

Avaliação do risco de contaminação por bactérias, no paciente submetido à broncoscopia, após o reprocessamento do broncoscópio

et al. 2002

Introdução: A broncoscopia é um procedimento diagnóstico e terapêutico realizado com a introdução nas vias aéreas de um tubo flexível que permite visualizar até as menores delas. Para evitar ou reduzir o risco de infecções, o broncoscópio deve ser adequadamente desinfetado com, pelo menos, desinfecção de alto nível. Objetivo: Verificar se há risco de contaminação bacteriana para os pacientes submetidos à broncoscopia do Hospital São Paulo da Unifesp, Estado de São Paulo. Métodos: No período de 1997 a 1998, o reprocessamento do broncoscópio incluiu limpeza e enxágüe com água estéril ou potável, seguida de rinsagem com glutaraldeído a 2% por 20 minutos, novo enxágüe com água estéril ou potável e rinsagem com álcool etílico a 70% e secagem com ar forçado pelo canal de sucção. Foram colhidas amostras de 65 pacientes para exames microbiológicos, instalando-se soro fisiológico estéril pelo canal de sucção do broncoscópio. Resultados: Após o reprocessamento foram encontrados nas amostras Staphylococcus epidermidis, Enterobacter sp, Acinetobacter baumanni, Streptococcus viridans, Staphylococcus aureus, Streptococcus beta hemoliticus A, Staphylococcus coagulase negativa e em cinco amostras houve crescimento de microbactéria na cultura. Conclusões: A desinfecç ão do broncoscópio com glutaraldeído a 2% não foi suficiente para garantir a desinfecção do aparelho e a presença de Staphylococcus epidermidis indica que houve contaminação do broncoscópio pela manipulação após a desinfecção.

“…4,5 However, even cleaning and disinfection have been a challenge because of the complex design of flexible bronchoscopes, 6 prompting the publication of guidelines. [7][8][9][10][11] Several bronchoscope-related outbreaks and pseudo-outbreaks of Pseudomonas aeruginosa and Serratia marcescens infection have been reported, [12][13][14][15][16][17] all of which resulted from some breach of the cleaning and disinfection guidelines. 9,11,18 In September 2001, an infection-control practitioner at a community hospital notified the Tennessee Department of Health of an increase in the number of P. aeruginosa and S. marcescens isolates associated with bronchoscopy.…”
