Análisis bacteriológico de superficies inertes y sensibilidad antibiótica en el Servicio de Cirugía General del Hospital Regional de Ica / Bacteriological analysis of inert surfaces and antibiotic sensitivity in the General Surgery Service of the Regional Hospital of Ica

RESUMEN

Objetivo: Identificar las bacterias presentes en superficies inertes del área de cirugía y conocer su respectiva sensibilidad antibiótica según corresponda. Materiales y métodos: Estudio observacional, descriptivo, transversal, prospectivo. Investigación para identificar microorganismos patógenos en superficies inanimadas del Hospital Regional de Ica. Se procedió a las tomas de muestra humedeciendo el hisopo en el caldo cerebro corazón y luego sembrado en agar sangre 5%, agar Mac Conkey y agar manitol salado, incubándolos durante 24 horas a 37ºC, tinción de Gram, pruebas de catalasa y oxidasa. Se realizó la primera lectura dentro de las 24 horas. Resultados: Estafilococus coagulasa negativo se aislaron en el lavadero, coche de medicación, mesa de comer, coche de curación de cirugía B y mesa de comer. Bacillus sp. se aislaron en pared y mesa de comer de Cirugía General. Staphylococsus aureus se aislaron en coche de medicación y coche de curación. Pseudomonas sp. Se aisló en mesa de comer de Cirugía General. El Staphylococcus aureus es resistente a la mayoría de antibióticos que usualmente se utiliza en el departamento de cirugía general del Hospital Regional de Ica. La Psudomona Sp. es resistente a antibióticos que usualmente se utiliza en el servicio de cirugía general, aunque es sensible a algunos antibióticos utilizados en este servicio. Conclusiones: Se encontraron gérmenes en superficies inanimadas que están en intimo contacto con pacientes del departamento de cirugía del Hospital Regional de Ica que pone en riesgo a contraer infecciones intrahospitalarias. El Staphylococcus aureus presenta mayor resistencia antibiótica que la Pseudomona Sp. (AU)

ABSTRACT

Objective: To identify the bacteria present in inert surfaces of the surgery area and to know their respective antibiotic sensitivity as appropriate. Materials and methods: Observational, descriptive, cross-sectional, prospective study. Research to identify pathogenic microorganisms on inanimate surfaces of the Regional Hospital of Ica. The samples were taken by moistening the swab in the brain heart broth and then seeded on 5% blood agar, Mac Conkey agar and salted mannitol agar, incubating them for 24 hours at 37 ° C, Gram stain, catalase and oxidase tests. The first reading was made within 24 hours. Results: Staphylococcus coagulase negative were isolated in the laundry, medication car, eating table, surgery B healing car and eating table. Bacillus sp. They were isolated in the wall and table of eating of General Surgery. Staphylococcus aureus were isolated in medication car and healing car. Pseudomonas sp. It was isolated on a General Surgery table. Staphylococcus aureus is resistant to most antibiotics that is usually used in the general surgery service of the Regional Hospital of Ica. And Psudomona Sp. Is resistant to antibiotics that is usually used in the general surgery service, although it is sensitive to some antibiotics used in this service. Conclusions: Germs were found on inanimate surfaces that are in intimate contact with patients of the surgical departament of the Regional Hospital of Ica, which puts them at risk of contracting nosocomial infections. Staphylococcus aureus has greater antibiotic resistance than Pseudomona Sp. (AU)
