The Effect of a Novel Air Decontamination-Recirculation System on Viable and Total Airborne Particulates During Surgery

Accepted for Presentation at the
European Bone and Joint Infection Society (EBJIS) 36th Annual Meeting
September 7 – 9 2017 in Nantes, France

Aim

The prevention of post-operative wound infection is important. The size range and amount of airborne particulate generated during different surgical procedures has not been extensively studied. We surveyed the airborne particulate generated across a range of orthopaedic, spinal and plastic surgery procedures (Phase 1). We also examined viable particles using a real time laser-induced fluorescence (LIF) system and bacteria cultures during routine arthroplasty surgery with and without a novel air decontamination-recirculation system (ADRS) (Phase 2).

Results

In Phase 1 the amount, size and timing of airborne particles correlated well with traffic and the surgical activity. Particles of 0.3-1 micron were generated throughout the whole procedure while larger particles appeared to be related to increased activity. The particle count versus time provided a profile for activity levels and the procedure itself. In Phase 2 the ADRS reduced the total and viable airborne particulates as well a colony forming units (CFU) per cubic meter. The LIF viable particle counter correlated well with the bacteria cultures and represents a surrogate measure of CFU with the advantage of continuous monitoring. Bacteria cultures provided a snap shot in time which is a limitation of this endpoint.
