Abstract

Information on pyrolysis products such as particle size distribution, concentration of plume aerosols and volatile organic compounds produced by laser treatment is required to evaluate the potential health hazards during treatment of biological tissue. In-vitro measurements and `in vivo' collection of samples were carried out for comparison. The concentration of pyrolysis products were determined for ENT and gynecological surgical laser treatments using a Nd:YAG laser and CO₂ laser. In consideration of the ventilation systems, room volume and suction efficiency the concentration of volatile organic compounds were measured by means of a multisorbent sampler and a gas chromatography system coupled with a FTIR spectrometer.
