Ultraviolet Lighting During Orthopaedic Surgery and Rate of Infection

In this study, Ritter et al. compared the disinfection efficacy of laminar airflow (LAF) and conventional UV light over a nineteen-year period in operating rooms during hip and knee replacement surgeries. The researchers found that the infection rate when using LAF was 1.77 %, but it decreased to only 0.57 % when using conventional UV light. It should be noted that using conventional UV light requires complete gowns and eye protection for staff and patients. This highlights the potential of using UV222 for decontaminating the air in operating rooms and reducing the risk of surgical site infections.
