Abstract

An infrared camera was used to measure the temperature rise which takes place in endotracheal tubes under laser irradiation. It was seen that a metallic tube was heated up within a second to temperatures of 200 degrees to 300 degrees Celsius which was very destructive to the PVC conduits inside of the tube. A compound tube, on the other hand, reached temperatures of only 38 degrees Celsius at its inner surface. The thermal induced destruction of the conduits inside of the metallic tube is seen as the reason for complications like airway blocking. Furthermore preliminary results of a randomized clinical study are presented, showing that the metallic tube needed higher pressure levels than the compound tube.
