The Evaluation of Pre-Post Smoke Evacuation Uses on Surgical Smoke and Bio-Aerosols in Operating Rooms

"The intervention group, using the smoke evacuation (RapidVac Smoke Evacuator) in each OR, the data collection for the amount of surgical smoke and bio-aerosols' particles will be collected during pre-surgery and during surgery (every 30 mins).~Before using the smoke evacuation, the amount of surgical smoke and bio-aerosols' particles in the surgical field and OR environment will be measured by AeroTraxTM Handheld Airborne Particle Counter. This record includes the amount and size of smoke and bio-aerosol particles in each area such as anesthetic area (anesthesiologist physicians and nurses area); instrument preparation area (circulating nurses area) and surgical area (surgeons and scrub nurses areas)."
