C-UVC units significantly reduce total and viable particle counts

Background

Airborne bacteria are a major source for wound contamination during total joint arthroplasty. Crystalline ultraviolet C (C-UVC) filter units were designed to disinfect and recirculate air in the operating room (OR). This preliminary study assessed the particle reducing capacity of C-UVC units in a highly controlled OR setting.

Objective

The purpose of this preliminary study is to measure the ability of a C-UVC unit to reduce airborne particulate matter related to OR foot traffic in a strictly controlled OR setting, prior to measuring it’s efficacy in an active, dynamic OR environment.

Reduction of Particles in the Operating Room Using Ultraviolet Air Disinfection and Recirculation Units

Results and Conclusions

The C-UVC unit at 4 m had significantly lower particle levels. C-UVC units have shown to be capable of significantly reducing TPC and VPC in a highly controlled OR setting. Reducing airborne particles using C UVC units may reduce infection rates following total joint arthroplasty.
