    Notes: Abstract Changes in arterial blood ketone body ratio (KBR) were investigated in 47 human liver transplantations. Of the 20 grafts preserved with University of Wisconsin (UW) solution, 10 had a cold preservation period of less than 10 h (UWS group) and 10 of more than 10 h (UWL group). In 27 other cases, grafts were preserved with EuroCollins (EC) solution for less than 10 h (EC group). In the EC group, KBR increased over 0.7 within 6 h after reperfusion of the graft in 17 cases (63%) and within 24 h in 7 cases (26%). In the 3 other cases, KBR failed to recover, and these patients underwent retransplantation. In the UW group, KBR recovered within 6 h in 13 cases (65%) and within 24 h in 7 cases (35%). There were no significant differences between the UWS and UWL groups. It is shown that the mitochondrial function of liver grafts preserved with UW solution can be well maintained even after extended preservation periods of more than 10 h.

    Description / Table of Contents: Zusammenfassung In der vorliegenden Arbeit werden die Adsorptionseigenschaften von 6 verschiedenen Materialien, die bei der Hämoperfusion eingesetzt werden in vitro geprüft: Amberlite XAD-2 und XAD-4, Haemocol, Collodium verkapselte Aktivkohle, Collodium verkapselte und Albumin beschichtete Aktivkohle und Aktivkohle-Hohlfaser. Carbromal wird am schnellsten eliminiert von Amberlite XAD-2 und XAD-4, ebenso Diazepam. Beim Vergleich der verschiedenen Kohlepräparate werden Carbromal und Diazepam am schnellsten von Haemocol aus der Lösung entfernt, Phenobarbital von Aktivkohle-Hohlfaser, wenn man eine 5-stündige Perfusion zu Grunde legt. Die gerinnungsphysiologischen und klinisch-chemischen Untersuchungen mit Hilfe von heparinisiertem Frischblut lassen schwerwiegende Nebenwirkungen erkennen. Die Abnahme der Thrombozyten ist am ausgeprägtesten bei Amberlite XAD-2 und XAD-4, sie ist aber auch bei den Kohlepräparationen nachweisbar: Nach 5stündiger Hämoperfusion ist ihre Zahl auf bis zu 10% des Ausgangswertes abgefallen. Die Hämolyse ist besonders stark bei Amberlite XAD-2 und XAD-4, sowie Haemocol. Die je nach Giftstoff unterschiedlich große Adsorption der geprüften Materialien und ihre verschieden stark ausgeprägten Nebenwirkungen erfordern nach unseren Ergebnissen einen der individuellen Situation des Patienten angepaßten Einsatz.
    Notes: Summary The properties of six adsorbents for Haemoperfusion were investigated in vitro: Amberlite XAD-2; Amberlite XAD-4; Haemocol; collodion coated charcoal; albumine-collodion encapsulated charcoal and activated carbon fibers. Carbromal and diazepam are most quickly removed from aqueous solutions by Amberlite XAD-2 and XAD-4. Of the charcoal containing materials, Haemocol eliminates most rapidly carbromal and diazepam; while activated carbon fibers remove phenobarbital faster. When heparinized blood is perfused, a remarkable reduction in platelet count is observed. The drop is most pronounced with Amberlite XAD-2 and XAD-4, but even when using charcoal preparations the platelet depletion can reach 10% of the original number over 5 hours. Haemolysis is most pronounced with Amberlite XAD-2, XAD-4 and Haemocol. As the efficiency of the adsorbents towards the various drugs differ and as their adverse effects also vary, the decision for a particular material will have to be made according to the individual case.
