HUAIRS system was utilized during two orthopedic procedures. After each surgical case the air inlet filtration cartridge was analyzed for deposited debris via scanning electron microscopy. Significant particle contamination was evident after each orthopedic procedure. Various types and morphologies of particles suggest that they originated from multiple sources. Suspected cell-derived fragments were evident.
Deployment of HEPA/UV-C Air Recirculation System (HUAIRS) in active urology operating room (OR) resulted in ˃ 95% reduction in 1 µm, 3 µm and 10 µm viable particulates as well as 84% decrease in air content of 5 µm particles. The decline in airborne particle contamination strongly correlated with bacterial quantification results in support of the efficacy of HUAIRS in improving OR air quality.
Airborne bacteria are a major source for wound contamination during total joint arthroplasty. C-UVC filter units are designed to disinfect and recirculate air in the operating room (OR).
Periprosthetic joint infection (PJI) is a common complication. This study revealed a reduction in infection rate through the use of intraoperative air decontamination system.
Airborne particulates generated during a range of orthopedic, spinal and plastic surgery procedures was measured with and without the HEPA Ultraviolet Recirculation System (HUAIRS). This evaluation found procedure and environment influences airborne particles and using the HUAIRS, total and viable particulates were reduced.
