In group 2 (<jats:italic>n<\/jats:italic>\u2003=\u200325) patients received aprotinin (30.000\u2003KIU\u00b7kg<jats:sup>\u22121<\/jats:sup> after induction of anesthesia, 30.000\u2003KIU\u00b7kg<jats:sup>\u22121<\/jats:sup> in the pump prime and 30.000\u2003KIU\u00b7kg<jats:sup>\u22121<\/jats:sup> after weaning from bypass).

In group 4 (<jats:italic>n<\/jats:italic>\u2003=\u200325) patients received a combination of the two agents in the same manner. Total blood loss and transfusion requirements during the period from protamine administration until 24\u2003h after admission to the intensive care unit were recorded. In addition, hemoglobin, platelet counts and coagulation studies were recorded.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> Postoperative blood loss was significantly higher in the control group (group 1) compared with children in other groups who were treated with aprotinin, tranexamic acid or a combination of the two agents (groups 2, 3 and 4) during the first 24\u2003h after admission to cardiac intensive care unit (40\u2003\u00b1\u200318\u2003ml\u00b7kg<jats:sup>\u22121<\/jats:sup>\u00b724\u2003h<jats:sup>\u22121<\/jats:sup>, aprotinin; 35\u2003\u00b1\u200316\u2003ml\u00b7kg<jats:sup>\u22121<\/jats:sup>\u00b724\u2003h<jats:sup>\u22121<\/jats:sup>, tranexamic acid; 34\u2003\u00b1\u200319\u2003ml\u00b7kg<jats:sup>\u22121<\/jats:sup>\u00b724\u2003h<jats:sup>\u22121<\/jats:sup>, combination; 35\u2003\u00b1\u200315\u2003ml\u00b7kg<jats:sup>\u22121<\/jats:sup>\u00b724\u2003h<jats:sup>\u22121<\/jats:sup>). The total transfusion requirements were also significantly less in the all treatment groups. Time taken for sternal closure was longer in the control group (68\u2003\u00b1\u200311\u2003min) compared with treatment groups 2, 3 and 4, respectively (40\u2003\u00b1\u200318, 42\u2003\u00b1\u200311, 42\u2003\u00b1\u200313\u2003min, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05).
