Abstract Electrocautery, laser tissue ablation and ultrasonic scalpel tissue dissection all generate a "surgical smoke" containing ultrafine (<100nm) and accumulation mode particles (<1µm). The objective of this study was to measure the amount of particulates in surgical smoke generated during various surgical procedures and to determine the particle concentrations to which operation room personnel are exposed using a condensation particle counter. Electro-cauterization and argon plasma tissue coagulation caused a very high number concentration (>100000/cm3) of particles in the diameter range of 10nm to 12µm. The peak concentration was confined to the immediate local surroundings. In the presence of an efficient air circulating system, ultrafine particles were evacuated within seconds. Other findings are discussed.
