Paper Abstract

Volatile organic compound (VOCs) emissions from laser surgery and electrosurgery were evaluated using a multisorbent sampler and capillary gas chromatograph system (GC). The experiments were carried out by vaporization of different tissues (liver, muscle, skin) under standardized conditions by use of CO2 and Nd:YAG lasers. As comparison the VOCs produced with an electrocauter surgical unit were investigated. With the use of a described sample and analyzer train a mixture of about 150 VOCs has been obtained. Up to now 15 substances have been identified as non-aromatic aldehydes, nitrils and aromatic hydrocarbons. The studies focus on quantitative results for these identified components. By use of the Toluene production the dependence of the emitted concentration on parameters as wavelength, power density, total energy applied, and tissue type can be shown.
