Análise de microrganismos patogênicos nas mãos de profissionais de saúde e em equipamentos hospitalares da unidade de terapia intensiva (uti) de um hospital regional

Abstract

INTRODUCTION: The hospital environment is a place that favors the spread of microorganisms, especially because it is constantly occupied by sick patients, facilitating the occurrence of Healthcare-Related Infections. The hands of healthcare professionals and hospital equipment, which are in direct contact with patients, they can be important vehicles and deposits of pathogenic microorganisms. OBJECTIVE: To analyze the presence of pathogenic microorganisms on the hands of healthcare professionals and on hospital equipment in the Intensive Care Unit of a regional hospital. METHODOLOGY: Research carried out in the ICU of a regional hospital in Caxias-MA, by collecting samples from the hands of 35 health professionals and 37 hospital equipment, totaling 72 samples. The samples were incubated for 24 hours, and microorganisms were isolated through sowing on Blood Agar and Methylene Blue Eosin Agar plates, and identification through morphological and biochemical analysis. The susceptibility profile of microorganisms was sought using the Kirb-Bauer technique, and the characterization of bacteria regarding the production of extended-spectrum beta-lactamase. RESULTS: The isolation of 108 microorganisms was found, of which 67 were classified as bacteria with the potential to trigger HAIs, of which: 14 Staphylococcus aureus, 14 Staphylococcus epidermidis, 13 Enterobacter spp., 8 Klebsiella pneumoniae, 6 Escherichia coli, 4 Streptococcus viridans, 3 Proteus spp., 2 Pseudomonas aeruginosa, 2 Serratia spp. and 1 Alcaligenes spp. In the susceptibility profile, 67.2% presented a high level of resistance to the antimicrobials tested, with emphasis on Gram negative microorganisms, which presented 65.8% resistant isolates. CONCLUSION: Thus, it was found that the hands of healthcare professionals and hospital equipment are important reservoirs of microorganisms, especially multi-resistant and ESBL producers. Therefore, hand hygiene by healthcare professionals and the cleaning and disinfection of equipment are essential measures to prevent and/or minimize harm to patient safety.
