Paper Abstract

Reactions of biological tissues treated with either laser or electrosurgery devices are mainly governed by the temperature field in the area of treatment. The dependence of the emission rate of volatile organic compounds (VOC) on the temperature of the reaction zone was determined in vitro for these devices. Different kinds of tissue (porcine liver, muscle and skin) were vaporized under standard conditions. Power settings of a Nd:YAG laser and a CO2 laser and those of an electrocauter were varied in different measurements. The temperature development in the area of treatment was determined with a thermocamera. VOCs were collected simultaneously under realistic conditions during the treatment. The samples were evaluated and analyzed using a multisorbent sampler and capillary gas chromatograph system (GC).
