[The effect of pulsatile perfusion on aortocoronary bypass grafting]

To evaluate the effect of pulsatile perfusion on myocardial protection and peripheral circulation, 23 patients undergoing aortocoronary bypass grafting were studied by dividing two groups; one with pulsatile perfusion technique (11 patients) and the other with non-pulsatile (12 patients). The cardiac functional assessments were made on CI, LVSWI, PCWP, CVP at 3, 6, 12 and 24 hours after the operation and the enzyme (CPK, CPK-MB, LDH, GOT) sampling were performed on 1, 2, 4 and 7 days after the operation. The difference between esophageal and rectal temperature, and urine output during cardiopulmonary bypass, indicating the peripheral circulation, were also measured. From these clinical results, it is concluded that pulsatile perfusion method is to be beneficial in myocardial protection and peripheral circulation during operation of aortocoronary bypass grafting.
