- Introduction: Intravascular fluids administered to patients may influence hemostasis. In patients undergoing cardiac surgery with cardiopulmonary bypass, the heart-lung machine is primed with 1300 ml of fluid. We assessed postoperative coagulation and platelet function in patients randomized to two different priming solu-tions, one colloid-based (dextran 40) and one crystalloid-based.Materials and methods: Eighty-four elective cardiac surgery patients were randomized to either a dextran-based prime or Ringer's acetate with added mannitol. Blood samples were collected before, and 2 and 24 h after cardiopulmonary bypass. Coagulation was assessed by standard coagulation tests and rotational thromboelas-tometry. Platelet function was assessed with impedance aggregometry. Bleeding volumes and transfusion re-quirements were recorded.Results: Comparing the groups 2 h after bypass, the dextran group showed lower hemoglobin concentration, hematocrit, platelet count, and fibrinogen concentration, and higher INR and aPTT, as well as longer clot for-mation time (+41 +/- 21 % vs. +8 +/- 18 %, p < 0.001) and a larger reduction in fibrinogen-dependent clot strength (-37 +/- 12 % vs.-7 +/- 20 %, p < 0.001). Adenosine diphosphate-dependent platelet activation was reduced in the dextran group but not in the crystalloid group 2 h after bypass (-14 +/- 29 % vs.-1 +/- 41 %, p = 0.041). No significant between-group differences in hemostatic variables remained after 24 h, and no significant differences in perioperative bleeding volumes, re-explorations for bleeding, or transfusion rates were observed.Conclusions: Compared to a crystalloid solution, a dextran-based prime had measurable negative impact on he-mostatic variables but no detectable increase in bleeding volume or transfusion requirements in cardiac surgery patients.
