Perfusion cooling by pulsatile flow.
Organ temperature changes and the temperature gradient between organs with cooling and rewarming were studied in rabbits using pulsatile flow perfusion. The temperature gradient between organs was within 3 degrees C. At the initial stage of cooling and rewarming, organ temperatures changed rapidly. During circulatory arrest, organ temperatures rose gradually. Brain temperature changes were similar to other organs.
