![]() Therefore, a minority of the bacteria that contaminated the wound are estimated to have fallen directly from the air. The average number of bacteria that was washed out after surgery was 35 times lower compared to when conventional ventilation was applied. ![]() It was found that the bacterial count in the air was substantially lowered, representing a 97-fold reduction, when laminar flow ventilation was used. Journal of Hospital Infection, 3(2), 123-135.Īn investigation regarding bacterial wound contamination during hip and knee replacement surgery was conducted in an operating suite using either laminar flow or conventional ventilation. The importance of airborne bacterial contamination of wounds. In this study, laminar airflow ventilation manages to maintain ultraclean air within the surgical protection zone but a 55-fold increase of the mean value of airborne colony forming units was observed outside the protected area compared to the value inside. One main aspect of avoiding surgical site infections is to ensure the sterility of the medical devices and instruments in the operating room and their location in the operating room is important. Influence on different ventilations systems upon the contamination of medical devices. Patients underwent total joint arthroplasty in operating rooms equipped with either LAF or turbulent airflow. With an appropriate perioperative protocol for infection prevention, LAF does not seem to play a protective role in PJI prevention. This study suggests that the use of LAF in the operating room was not associated with a reduced incidence of PJI after primary total joint arthroplasty.
