“…[8][9][10][11] To assess the effects of different designs, French (Fr) sizes, position and negative pressure on flow through femoral venous cannulae, gravity siphon drainage was compared to that augmented by a centrifugal pump. Published flow-charts have been available since the early perfusion literature [12][13][14] and are currently supplied by cannula manufacturers. Previous reports have documented venous cannulae flows in the laboratory [15][16][17][18][19][20] or clinically.…”

“…The rate of flow obtainable during cardiopulmonary bypass is generally limited by the length and orifice diameter of the venous cannulae 7 • Other factors that effect the rate of venous flow include position of the cannulae in the vena cavae, the pressure gradient and resistance across the venous circuit 8 , and mechanical factors such as kinks in the venous line.…”

“…Die extrakorporale Zirkulation führt durch Traumatisierung der Erythrozyten in Filtern und Pumpen zur Hämolyse, deren Bedeutung für das NV aber noch nicht geklärt ist. Experimentell und klinisch ist lediglich erwie-sen, daß freies Hämoglobin das Glomerulumfiltrat senkt und im Zusammenwirken mit einer Vasokonstriktion zur Tubulusnekrose führen kann (2,14,16,17,26,28,34).…”
