Changes in advanced hemodynamic monitoring during major gynecological abdominal tumor surgery. Advanced hemodynamic monitoring was established after induction of anesthesia and before beginning of surgery. Cardiac index (CI), stroke volume index (SVI), stroke volume variation (SVV), and systemic vascular resistance index (SVRI) were measured continuously by pulse contour analysis. Baseline values before beginning of surgery are plotted on left Y axis (median values indicated by black bar). Intraoperative values were normalized to the baseline and are given as percentage change (plotted on right Y axis, median indicated by red bar) Figure shows absolute values with the respective median, the thin line indicates the level of baseline value (100%).
