Peripheral tissue blood flow (PTBF) of the index finger was measured by laser flowmeter during extracorporeal circulation (ECC) in coronary revascularization patients (group I n=15) and in repair of ASD or VSD patients (group II n=5) respectively. Before ECC, PTBF mesured in group I was 17.3±15.5 and that in group II was 18.61±9.0. But during ECC, PTBF of group I was 17.9±8.1 and higher (p<0.01) than 1.4±0.5 which was measured in group II. And Correlations between PTBF and hematocrit, systemic vascular resistance index and urine output during ECC were not significantly different.
