[Ischemia, hypothermia, length of death-perfusion and temperature related factors for preservation of organs].

In order to guarantee the comparability of the results of the various working teams and experimental conditions within the preservation of organs, above all of the preservation of kidneys, it is referred to the importance which belongs to the clear establishment of the used notions, such as time of hyperthermy (duration), time of ischaemia and dead time (warm and cold). For the practice of kidney taking simple time determinations between two steps of taking have made their way. The warm dead time is the duration between clamping of the renal vessels and the beginning of the flow with cold preservation solution. This establishment is justified by the standardised conditions of taking. For reserach these pauschal temporary data are not sufficient and the exact establishment of the notion used is necessary.
