Abstract
New system of our blood pump has been tested in 1-atrio femoral bypass in 11 dogs. Their pumping was controlled automatically by changing the pumping rate and the stroke volume according to the preload and the afterload. Results obtained were as follows. 1) no heparin, 2) can be started by anyone, even untrained, by only turning the switch on, 3) maintained automatically, 4) bypass rate was 50 to 90% of normal cardiac output, 5) easier weaning, by only extracting the inflow duct without re=opening the chest, 6) extreemly lower cost, 7) easier transportation of the patient.
Thus, this simple methode may be more convenient and easier for use after cardiac surgery, as same as IABP.
