Evaluación microbiológica del aire y las superficies de las áreas de quirófanos del Hospital del Instituto Ecuatoriano de Seguridad Social de Riobamba.

Abstract

Health facilities are environments where people greater or lesser degree have problems with their health congregate. In this context the environment hospital is a space in which they can get nosocomial infections with the consequent deterioration of existing clinical picture. In the present study evaluations in hospital environments of a public hospital at Riobamba city, Ecuador taking into account the most vulnerable areas such as surgery rooms were made the method swab was used, whereas for air samples sedimentation Method or open plate was used to process the samples were the incubated for 24 to 48 hours at 37 °C. for collecting surface samples for identifying microorganisms found microbiological identification tests as primary oxidase, catalase and Gram staining was used together microbial identification kits Microgen TM GN ID A+B In 4 surgery rooms evaluated 0.68,1.04,0.23,0.58 CFU/cm2 was obtained for each operating room, getting less than the values reported in the UNE EN ISO 14698, while in the air evaluation, surgery rooms would be in the category of very clean environments established by the UNE-EN ISO 14644-1:2000 indicating that must have <10 CFU/cm3 of air to belong to this classification. The most frequently identified microorganisms were Escherichia coli, hafnia alvei, Citrobacter freundi, Burkholderia pseudomallei.
