Objective: The present study aimed to determine the generation and behavior of airborne particles that could carry microorganisms around the area of the feet while walking in a bio-clean operating room.
Methods: Four surgical staff members performed four walking patterns comprising combinations of the following: independently or as a group, and entering or exiting the operating room.
Results: Fine particle visualization and laser particle counts revealed large numbers of airborne particles on shoes, the hems of gowns, and the floor regardless of the walking pattern. Numerous airborne particles were generated by followers who walked in groups and even more particles were brought to the level of the operating table by groups compared to solitary walkers.
Conclusion: Surgical staff should be aware of transferring airborne particles from non-sterile areas to reduce the incidence of contamination by airborne bacteria in bio-clean rooms.
