Popis: The thermographic camera has been used to measure the surface temperature of the skin in subjects undergoing laser therapy for treatment of their port wine stains. Skin temperatures during therapy with the tunable dye laser reached a maximum of 46 °C at 6–7 J output. A normal subject showed a skin temperature of 38 °C at 5 J output and 46 °C at 10 J output. Skin temperatures during argon laser therapy in continuous mode reached estimated maxima of approximately 75 °C at an output of 1.2 W. A normal subject showed temperatures of 45–50 °C with a 0.2 s pulse at 1 W output and 50 °C with a 0.5 s pulse at 1 W output. At 5 W, the normal subject showed temperatures in excess of 70 °C with either 0.2 or 0.5 s pulses. The conclusion must be reached that there is little chance of heat damage to the skin with the tunable dye laser, but that heat damage to the skin in general is a significant risk with the argon laser.
