The aims of our study were to describe the hemodynamic effects of normovolemic hemodilution and to determine its effect on systolic and diastolic cardiac function by multiplane transesophageal echocardiography. Purpose Acute normovolemic hemodilution ( ANH) is an autologous transfusion method, using blood collected during surgery, to reduce the need for allogeneic blood transfusion. The use of acute normovolemic hemodilution ( ANH) during heart– lung bypass in cardiac surgery was first described in 1957, 1 but it was not used in non- cardiac surgical procedures until Messmer et al.
