Evolution during the first 24 h of hemodynamic variables in transfused and non-transfused patients. A ΔPCO_{2 fem}. B SvO_{2 fem} and C lactate. All data are reported as mean ± SD. *P < 0.05; **P < 0.005; ***P < 0.001. Parameters were measured at hospital admission and over the first 24 h. ΔPCO_{2 fem} femoral venous-arterial difference in carbon dioxide pressure. SvO_{2 fem} femoral venous oxygen saturation
