Abstract

Highlights
•Airborne particles released from surgical team members are major sources of surgical site infections.
•Effect of surgeon’s posture on particle distribution within the surgical area is not well known and documented.
•Mobile laminar units were investigated as an addition to conventional turbulent-mixing operating theatre.
•With proper work practice, the laminar units reduced the airborne bacteria concentration down to an acceptable level.
•Lower source strength in general resulted from a high protective clothing system reduce the bacteria concentration.
