Abstract:
30% after ANH) and blood volume was maintained with crystalloid and colloid (1 : 3) . The preoperatively collected blood and the blood salvaged during operation were infused back to the patient after CPB. The operations were performed under CPB with moderate hypothermia. In patients undergoing atrial or ventricular septal defect tranexamic acid 20 ml-kg-1 was given and in other patients aprotinin 5 000 000 U was given. Hb, Hct and platelet count (PLT) were measured and recorded before operation, after ANH and 24h after operation. The volume of RBC salvaged during operation, CPB time and the volume of chest tube drainage at 24h after operation, the volume of whole blood, plasma, packed RBC, cryoprecipitate and platelet transfused and hospitalization time were also recorded. Results The demographic data were comparable between the two groups. There was no significant difference in CPB time and the total days of hospitalization between the two groups. The Hb at 24h after operation was significantly higher in group A +C [(122.2+18.8)g/L] than that in group C [(112.3+15.6)g/L] (P
