OR Package Studies

Please visit the following links to review articles from as far back as 1935, in publications that include The Journal of Bone and Joint Surgery, the American Academy of Orthopedic Surgeons, and Annals of Surgery. Studies address topics that include using UV light during orthopedic surgery; benefits of using UV in the OR; and using ultraviolet light to reduce unexplained infections in a clean wound.

Testing

Irradiating the air and surfaces with safe and effective UVC energy before, during, and after a procedure has been shown to reduce post-operative infections. An infection at the site of a surgical wound is a complication that prolongs recovery times for patients, and can be fatal.

Roughly 290,000 patients every year contract infections while undergoing surgery, according to the Centers for Disease Control and Prevention. The CDC also reports that SSIs represent 20% of all health care acquired infections (HAIs), and the Center for Healthcare Design (CHD) estimates that more than 30% of SSIs are caused by airborne pathogens.

The primary sources of bacteria transmitted to the surgical site through the air are squames, or skin scales. Approximately 1.15 × 106 to 0.9 to 108 squames are generated in a typical two to four hour surgical procedure, according to a study published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

OR Package Coverage

Full and complete coverage is provided by the hard-mounted UVC OR package. Shadowed areas are minimized or eliminated, and only one cycle is required for full UV disinfection.
