Figure 2

Changes in (a) oxygen delivery index and (b) central venous oxygen saturation following surgery in the three treatment groups. *Significant difference between groups over time for oxygen delivery index (DO2I) and central venous oxygen saturation (ScvO2; P < 0.0001; two-way repeated measures analysis of variance). Significant increase in DO2I over time: SV group P = 0.003; SV & DPX group P < 0.0001. Significant increase in ScvO2 over time: SV & DPX group P < 0.0001; no change in the SV group (P = 0.22) or CVP group (P = 0.98). †At hour eight, there was a significant difference in DO2I between the CVP and SV & DPX groups (P < 0.001) but no difference between the SV and CVP groups (P > 0.05). At hour eight, there was a significant difference in ScvO2 between the CVP and SV & DPX groups (P < 0.05) but no difference between the SV and CVP groups (P > 0.05). CVP, central venous pressure; DPX, dopexamine; SV, stroke volume.
