Time course of intraoperative haemodynamic parameters.

<p>Time course of stroke volume index (SVI) of the two intervention groups displayed by ODM (A1) and PPA (A2); time course of pulse pressure variation (PPV) of the two intervention groups displayed by PPA (B) and systemic vascular resistance index (SVRI) of the two intervention groups displayed by ODM (C). Data are shown as median (25%; 75%) quartiles over the time course of surgery and the nonparametric analysis for the parameters that are outlined with corresponding p values. Statistical significances: # for comparisons with respect to time points within the group (exact Wilcoxon tests); #1: p<0.05 vs. T1, #2: p<0.05 vs. T2, #3: p<0.05 vs. T3 and * for comparisons between the ODM and PPA group (Mann-Whitney tests) with p<0.05 at the time point ODM group vs. PPA group.
