| Popis: | Cardiac displacement during off-pump coronary artery bypass (OPCAB) surgery causes a fall in cardiac output. Here, we investigate how this drop in systemic perfusion is transferred to the oxygenation of sublingual and cerebral tissue. Sublingual microcirculatory perfusion or microcirculatory hemoglobin oxygen saturation (mu HbSO(2)) measurements were performed using sidestream dark-field imaging and reflectance spectrophotometry, respectively (both n=12). The cerebral tissue oxygenation index was measured by near-infrared spectrophotometry (n=12). Cardiac output was calculated by pulse contour analysis of arterial pressure. Cardiac displacement reduced the cardiac output from 4.3 +/- 0.8 to 1.2 +/- 0.3 l/min (P |
