Resumo
Infecções Relacionadas à Assistência à Saúde (IRAS) são foco de atenção nas
unidades de terapia intensiva (UTI), tendo em vista o risco para os pacientes
internados. Este estudo apurou a presença de bactérias em superfícies,
vestimentas e mãos em UTI de hospital público no norte de Santa Catarina.
Para isso, foram coletadas amostras para isolamento e identificação por
automação e/ou métodos manuais. Entre as 39 amostras coletadas, as
bactérias encontradas foram: Enterococcus faecalis (25,64%), Staphylococcus
spp (12,82%), Bacillus spp. (10,25%), Staphylococcus aureus (7,69%),
Staphylococcus spp. coagulase-negativa (7,69%), Enterococcus faecium
(5,12%), Staphylococcus epidermidis (5,12%), Staphylococcus equorum
(2,56%), Staphylococcus hominis (2,56%), Streptococcus spp. (2,56%),
Pseudomonas aeruginosa (2,56%), Proteus mirabilis (2,56%), Klebsiella
pneumoniae (2,56%). O isolado de Klebsiella pneumoniae foi identificado como
multidroga-resistente, produtora de carbapenemase e beta-lactamase de
espectro estendido (ESBL). Conclui-se que tais achados são importantes para
conscientização quanto a necessidade de elaboração de plano de ação para
reduzir a incidência de bactérias patogênicas, em especial as
multidrogas-resistentes, para garantir a segurança dos pacientes.
Hospital-acquired infections are the main concern in intensive care units (ICU), as they pose a risk for the patients under care. This research investigated the presence of bacteria in the hospital environment such as surfaces, scrubs and hands of healthcare professionals in an ICU of a public hospital in the north of Santa Catarina. For this purpose, samples were collected for bacterial isolation and characterization through automated and/or manual methods of identification. Within the 39 samples collected, the bacteria found were: Enterococcus faecalis (25,64%), Staphylococcus spp. (12,82%), Bacillus spp. (10,25%), Staphylococcus aureus (7,69%), Staphylococcus spp. coagulase-negativa (7,69%), Enterococcus faecium (5,12%), Staphylococcus epidermidis (5,12%), Staphylococcus equorum (2,56%), Staphylococcus hominis (2,56%), Streptococcus spp. (2,56%), Pseudomonas aeruginosa (2,56%), Proteus mirabilis (2,56%), Klebsiella pneumoniae (2,56%). One of the most concerning findings was an extended-spectrum-beta-lactamase and carbapenemase producing Klebsiella pneumoniae strain was identified as multidrug-resistant. Thus, these reports are significant to raise awareness for the need of establishing an action plan to reduce the incidence of pathogenic bacteria, particularly the multidrug-resistant, to insure patient safety.
