Abstract nosocomial infections occur worldwide and affect both developed and developing countries. Airborne associated infections represent one third of all nosocomial infections. Operating rooms are classified into ultra-clean and clean operating rooms according to the type of their ventilation. Operating room ventilation is essentially designed to reduce airborne infection by removing or diluting airborne microorganisms originating from the environment or operating theatre staff. It is important to assess the airborne contamination of healthcare facilities when the maintenance of clean environment is required. Evaluation of the air quality in operating rooms can be performed routinely by microbiological sampling and particle counting. Chemical disinfectants are widely used in infection control. Among the various disinfectants that satisfy most of the requisites are hydrogen peroxide and its compounds. They yield very good results in terms of disinfection efficacy and seem to be able to replace the currently used substances that are more problematic from a toxicological stand point. In the current study, air and surface samples were collected from fourteen operating rooms in El-Demerdash University Hospital during February 2011, the studied rooms were divided into three groups according to the applied infection control measures. The samples were collected after terminal cleaning, nebulization of Bafry, spraying of Bafry and spraying of Huwa-San (one at a time). A significant decrease in microbial air counts was observed after the use of the two hydrogen peroxide formulas, however, this decrease was greater with Bafry than Huwa-San. There was no observed difference between the use of Neburotor Europa and the Automist, however, the use of Neburotor is better because the full automation of it decreases the exposure of the workers to the disinfectants. |
