Utilization of activated carbon hemoperfusion to assist recovery of ischemically damaged canine liver allografts.

abstract：:Nonpulsatile blood pumps are mainly used in extracorporeal life support systems. Although pulsating blood flow is known to be physiological, a pulsatile pump is not commonly applied in a circuit with a membrane oxygenator because of damage to the blood cells. The hypothesis that the placement of a pressure-relieving c...
