Figure 4

Changes in tissue oxygenation following surgery in the three treatment groups. *Significant difference between groups over time (P = 0.0005; two-way repeated measures analysis of variance). Significant increase in tissue oxygenation (PtO2) over time in the SV & DPX group (P = 0.0003), no change in the SV (P = 0.14) or CVP groups (P = 0.20). †At hour eight, there was a significant difference in PtO2 between the SV & DPX and CVP groups (P < 0.005) but not between the SV and CVP groups (P > 0.05). CVP, central venous pressure; DPX, dopexamine; SV, stroke volume.
