Medical applications (Dermatology, HF surgery)

Laser surgery is a source of hazardous particles. The aerosols derived from laser surgery consist of parts of human tissue that become airborne when the tissue is being treated with the laser beam. The fume and vapours released by laser surgery spread explosively while the actual health hazard comes from microbes such as bacteria, fungi and viruses smaller than 2µm. When these microbes are inhaled they settle in the lung. Thus, they impose a serious infection risk on surgery staff as well as on the patients.

Dangers and hazards in the laser surgery

The surgery facemask doesn’t offer protection in front of air-suppor- ted particles. Up to 25% of the respiratory is passing the facemask! It was developed around the patient to protect him from an airborne infection by the operation staff.

In the laser surgery aerosols will be generated with a particle size of 0,1μ -10μm. Those laser aerosols (LGAC = Laser Generated air- boune Contaminants) consist of serveral parts of human fabric. This one being removed from the fabric explosively as a steam or gas mixture. Dangers start out from microorganisms like bacteria, viruses and fungi. These have a particle size of smaller than 2μ and can be completely breathing in and therefore are deposited in the lungs. There is an acute infection risk with that for the operating staff and patient.
