Avaliação da eficácia de um nebulizador de alta vazão na desinfecção de ambientes hospitalares

Abstract

The hospital segment lacks automated and efficient solutions with regard to the disinfection of environments, depending on traditional tools and methods that are subject to human error. This study aims to evaluate the effectiveness of nebulization as a disinfection process in hospital environments. The equipment used has already passed preliminary tests, followed by tests with microorganisms that cause nosocomial infections. Therefore, a biological evaluation protocol - Spread plate, was adapted and used in the assessment of the population reduction of K. pneumoniae carbapenemase after nebulization of a sanitizer with quaternary ammonium active principle. The experiment carried out in triplicate showed that the operation was capable of destroying 6 logarithmic cycles of the enterobacteria, showing no growth in the Test Group of the samples.
