ABSTRACT
Objective To observe the changes of hemorheology after acute hypervolemic hemodilution (AHH), and provide theoretic basis for clinical rationally using artificial plasma substitutes. Methods 90 patients undergoing hip joint operation were randomly divided into 3 groups (each group containing 30 patients), which received intravenous infusion of 6% hydroxyethyl starch (HES), 4% gelofusine or ringer's solution at 20ml/kg, respectively before operation. The whole blood viscosity, plasma viscosity, Hct, index of RBC aggregation and index of RBC deformation were measured before and after hemodilution. Resutls Hemodynamics was stable after AHH, and the amounts of perioperatively blood transfusion in the patients received colloid solution were obviously less than those in the patients received crystalloid solution. The whole blood viscosity, Hct and index of RBC aggregation significantly decreased after AHH in all the patients, and index of RBC deformation markedly increased in the patients after AHH with 6% HES. Conclusion AHH could effectively maintain hemodynamics stable, improve hemorheological condition and perfusion of microcirculation, enhance the tolerance of blood loss, and reduce homologous blood transfusion. Colloid solution was better than crystalloid solution for AHH.
