Rastreamento de bactérias em leitos de um hospital regional da Paraíba, Brasil.

Abstract

Hospitals have an environment that offers patients the risk of infection by various microorganisms, an example of Staphylococcus aureus, bacteria that can remain viable on emanated surfaces for several days. Therefore, this study aimed to track bacteria on bed mattresses of a Regional Hospital in Paraíba. The collections of the collections were carried out in 12 bed mattresses, after a disinfection process carried out by the nursing team. For collection, sterile SWABs moistened with saline were used, then these were inserted into test tubes containing Brain Heart Infusion (BHI) to be transported to the laboratory. After arrival in the laboratory, tubes with BHI were incubated at 36 ° C for up to 48 hours, then sowing was carried out in the media, which in view of bacterial growth, macroscopic evaluation of colonies, Gram staining, optical microscopy and biochemical tests were carried out. . At the end of the research, S. aureus was not detected, but other microorganisms were found, such as Escherichia coli, which corresponded to 5 (50%) of the fertilizing bacteria. In conclusion, even after cleaning, 83.33% of the mattresses provided remained with some contamination, with emphasis on the stabilization and medical clinic sectors, although the mattresses sampled in the small dressing room and surgical block were free from contamination, the fact may put users' health at risk, requiring a review of the disinfection protocols used by the Hospital.
