[Effect of temperature on the donor and the thrombocyte function in thrombopheresis with a cell separator (Aminco)].

In the continuous cell separation (Aminco) the temperature of the extracorporal blood is diminished by 9.3 degrees C. The calculated cooling of the intracardiac blood of 0.1 degrees C does not lead to an irregular cardiac rhythm. The donor only needs 0.339 kcal/min to rewarm the blood. It is necessary to rewarm the blood before retransfusion only if you have proved evidence of coldness antibodies with an extremely wide amplitude of temperature.
