Objective: to determine the microbiological profile of bacteria isolated and identified from beds and infusion pumps in the intensive care unit of a university hospital in Rio de Janeiro state. Method: nine samples were collected from patients’ bed side rails and eight from infusion pump keypads in an intensive care unit in October 2014. An area of 100cm² was delimited as the sampling parameter. Samples were collected using sterile swabs, which were wetted and transported with Cary-Blair. The microorganisms were isolated, classified, and then tested for antimicrobial resistance. Results: coagulase-negative Staphylococcus was the most prevalent type. Antimicrobial susceptibility testing indicated some of these Staphylococci were multi-drug resistant. Conclusion: multi-professional discussion of hospital safety issues must be expanded, and continuing professional development emerges as one possible pathway to success in nosocomial infection control.
RESUMO
Objetivo: determinar o perfil microbiológico de bactérias isoladas e identificadas nos leitos e bombas infusoras na unidade de terapia intensiva de um hospital universitário do Estado do Rio de Janeiro. Métodos: foram coletadas nove amostras de grades das camas dos pacientes e oito de teclados de bomba infusora de uma unidade de terapia intensiva, em outubro de 2014, delimitando-se uma área de 100cm² como parâmetro para ambas as coletas. As amostras foram coletadas através de swabs estéreis que foram umedecidos e transportados em Carry & Blair. Os microrganismos foram isolados, classificados e depois testados em relação à resistência antimicrobiana. Resultados: o gênero Staphylococcus coagulase negativa foi o mais prevalente. Os testes de suscetibilidade a antimicrobianos apontaram alguns destes Staphylococci como multirresistentes. Conclusão: chama-se atenção para a necessidade de ampliação do debate multiprofissional sobre questões de segurança hospitalar, apresentando a educação permanente como um possível caminho de sucesso no controle das infecções.
RESUMEN
Objetivo: determinar el perfil microbiológico de bacterias aisladas e identificadas en las camas y las bombas de infusión en la unidad de terapia intensiva de un hospital universitario de Rio de Janeiro. Métodos: se recolectaron nueve muestras de rejas de camas de pacientes y ocho de paneles de las bombas de infusión de una unidad de terapia intensiva, en octubre de 2014, delimitandose un área de 100 cm2 como parámetro para ambas recolecciones. Se recolectaron las muestras a través de swabs estériles que fueron humedecidos y transportados en Carry y Blair. Los microorganismos fueron aislados, clasificados y después probados repecto a la resistencia antimicrobiana. Resultados: el género Staphylococcus coagulasa negativo fue el más prevalente. Las pruebas de susceptibilidad a antimicrobianos mostraron algunos Staphylococci como resistentes a múltiples fármacos. Conclusión: se señala la necesidad de ampliación del debate entre los profesionales de la salud, sobre cuestiones de seguridad hospitalaria, presentando la educación permanente como un posible camino de éxito en el control de las infecciones.
