The Effects of a Novel Decontamination-recirculating System in Reducing Airborne Particulate: a Laboratory Based Study
Accepted for Presentation at the
European Bone and Joint Infection Society (EBJIS) 36th Annual Meeting
September 7 – 9 2017 in Nantes, France
The prevention of surgical-site infection (SSI) is of great importance. Airborne particulate correlates with microbial load and SSI. There are many potential sources of airborne particulates in theatre and from an experimental point of view impossible to control. We evaluated the effectiveness of a novel air decontamination-recirculation system (ADRS) in reducing airborne particles in a laboratory environment and controlled the introduction of particulate using diathermy.
The ADRS significantly reduced baseline airborne particles in the empty PC2 laboratory. When using electrocauterization (as a source of particle generation), peak particles were significantly higher at 0.5m compared to 3m. Small particles (0.3-0.5 microns) were reduced at 0.5m with ADRS whilst larger particles were not. The ADRS significantly reduced all particles of 0.3-10.0 microns at 3m. Particles also returned to a lower baseline and at a faster rate with the ADRS.
