ABSTRACT

Introduction: Laryngoscope metallic blades are potential infection sources to have contact with the patient’s oral mucosa during intubation. Handle is contaminated when the blade is folded, microorganisms can then be transmitted to gloves and hands of anesthesiologists. The objective was bacterial identification of laryngoscopes and hands of anesthesiologists compared with pathogens found in nosocomial pneumonias reported in Mocel Hospital. Material and methods: It was taken cultures of anesthesiologist´s hands, blade and handle of the laryngoscope prior to 40 patients intubation. Specimens were inoculated onto blood agar and Thioglycolate broth incubating at 37 °C for 72 hours and identification of microorganisms. The revision of patients was at 12, 24, 48 and 72 hours. Results: Positive cultures: Hands: 19 (47.5%), Staphylococcus epidermidis (36.8%), Pseudomona aeruginosa (26.3%), Staphylococcus aureus (10.5%). Handle cultures: 21 (52.5%), Staphylococcus epidermidis (42.8%), Pseudomona aeruginosa (23.8%), Staphylococcus hominis (9.5%). Blade cultures: 11 (27.5%), Staphylococcus epidermidis (27.2%), Pseudomona aeruginosa (18.8%), Staphylococcus hominis (18.8%). When these results are compared with nosocomial pneumonias reports coincide bacteria as: Pseudomona aeruginosa, Staphylococcus aureus, Staphylococcus warneri, Enterococcus faecalis and Staphylococcus hominis. No patient presented pneumonia. Conclusions: The bacteria found are potentially pathogenic, it is necessary to apply high-level disinfection methods.
