Abstract: Although the attainment of normal hemodynamic values has always been assumed to be the therapeutic target for critically ill patients, recent studies reported increased values in oxygen transport varia bles in survivors of high-risk surgery. It has been supposed that the higher values observed in survivors might indicate a physiological compensation for the increased metabolic requirements due to disease. We designed a randomized, multicentric trial to evaluate the effect of high values of cardiac index(CI) and oxygen delivery (DO2) in critically ill patients. Patients enrolled in the study are randomized to three different hemodynamic targets:normal values of CI (2.5 < CI < 3.5 L min m, and mixed venous oxygen saturation (SvO2) > 70% or (Sata-Satv) < 20%. Two different monitoring systems are used to maintain the target: conventional Swan-Ganz catheter with scheduled samples of mixed venous O2 saturation, and optical catheter with continuous SvO2 evaluation.
