As a result of laser imaging studies in an ultraclean theatre we concluded that obstructions to horizontal airflow at the periphery might produce areas of high particulate residence times. High residence times may allow a higher proportion of infected particles to land. We decided to investigate this effect by placing
Deep infection occurs in 2–4% of lower limb arthroplasty resulting in increasing cost, co-morbidity and challenging revision arthroplasty surgery. Identifying the potential sources of infection helps reduce infection rates. The aim of our study is to identify the impact and potential for contamination of our hands and gowns whilst scrubbing using SSHS. A colony-forming unit (CFU) is a pathogenic particle of 0.5 micrometers to 5 micrometers. Concurrent particle counts and blood agar exposure
