[Comparative temperature measurement by thermoprobes and infrared pyrometry in the rewarming of frozen kidneys using short wave generators].
Mini pigs' kidneys were frozen to -20 degrees C after initial hypothermic perfusion and cryopreparation with dimethyl sulphoxide. They were subsequently thawed out with short-wave radiation. During this procedure continuous temperature measurement is only possible using infra-red pyrometry without physical contact. After completion of short-wave irradiation at ca. 4 degrees C the surface and internal temperatures are measured with thermoelements. In comparison with measurement by thermoprobes, infra-red pyrometry proves to be quite practicable, with certain limitations. If a homogeneous distribution of temperature in the organ is assumed; the internal temperature could be calculated from the surface temperature. Also, continuous observation of temperature changes ist possible.
