About this trial
The impact of acute normovolemic hemodilution (ANH) using hydroxyethyl starch before initiating cardiopulmonary bypass (CPB) on whole blood viscoelastic profile after CPB has not been well established. Patients undergoing cardiac surgery employing moderate hypothermic CPB are randomly allocated into one of two groups: in Group-ANH, ANH is applied by using a balanced hydroxyethyl starch (HES 130/0.6); and in Group-C, ANH is not applied. After weaning from CPB, intergroup differences of INTEM, EXTEM, FIBTEM, and APTEM profiles are analyzed. As a primary outcome, the inter-group differences between maximal clot firmness of EXTEM will be determined at 10 min after ANH in Group-ANH and that at control.
