Study summary

We evaluated the impact on macrocirculatory hemodynamics and microcirculation in patients after cardiac surgery and compared the evolutions of those parameters between patients with tissue hypoperfusion and normal perfusion. Consecutive patients after cardiac surgery who required mechanical ventilation and for whom sublingual microcirculation measurements were possible enrolled.
