Changes in Microcirculatory Perfusion Using Acute Normovolemic Hemodilution (ANH) with HES (130/0,4) During Cardiac Surgery

Cardiac surgery remains a major consumer of blood components. ANH provides fresh autologous blood units for later retransfusion after control of surgical bleeding. The real efficacy of ANH in reducing allogeneic blood transfusions is discussed controversially in the literature. Thus, the present investigation was performed to effects of ANH with HES (130/0.4) on microcirculation in cardiac surgery.
