On average, consumption because of activation resulted in less than a 1% drop in the concentration of coagulation and fibrinolytic factors during cardiopulmonary bypass. Conclusions: Hemodilution is the primary cause of the drop in coagulation and fibrinolytic proteins during routine cardiopulmonary bypass, followed by blood loss, whereas consumption accounts for less than a 1% Hemodilution of 60% and 80% significantly decreased clot strength (maximum amplitude) and the kinetics of clot development (α angle) and increased the clot formation time (K). Abstract. The effects of intravenous fluids on hematocrit are debated.

152 p. In all animals, acute isovolemic hemodilution resulted in a significant decrease in MAP and in SVR (table 1). In the 1.0 MAC halothane group, CI increased, mainly through an increase in SI. In the 1.5 MAC halothane group, neither CI nor SI increased. 2008-04-23 · BackgroundCerebral blood flow (CBF) is auto-regulated to meet the brain's metabolic requirements. Oxycyte® is a perfluorocarbon emulsion that acts as a highly effective oxygen carrier compared to blood.

Other design characteristics did not show strong significant effects. The mild hemodilution does not have a high negative impact on the oxygen-carrying capacity of blood, blood coagulation or in the heart, brain and kidneys, while allowing the collection of enough autologous blood; 3) When a large amount of blood needs to be collected, erythropoietin and iron are administered to promote the formation and maturation of erythrocytes in patients, preventing preoperative anemia.

Iatrogenic hemodilution: a possible cause for avoidable blood transfusions?

Hemodilution effect

Hemodilution has the largest effect on drugs whose distribution is primarily confined to the bloodstream. The impact of hemodilution is less for drugs with a large volume of distribution because drug diluted in the bloodstream may be replaced by drug stored in the tissue. Further, the impact of hemodilution is inversely related to age. RESULTS: Three groups were clinically similar regarding blood loss, mean arterial pressures and coagulation parameters. But allogeneic transfusion requirements were significantly less in hemodilution groups (20% in ANH, 40% in HHD) compared to the control group (100% of patients).

Blood Viscosity and Shock - H Goslinga - Häftad - Bokus

A slight rise in the mean Pa02 value from 43.5 ± 5 In isovolemic hemodilution, although lacking volume-expanding effects to increase cardiac output, the reduced viscosity lowers the peripheral vascular resistance, which may also increase cardiac output by reducing ventricular afterload and increasing venous return. 25 26 Hemodilution elicits venomotor activity dominated by aortic chemoreceptors and results in increased venous return, which may also be a factor that influences cardiac output by lowering viscosity. 27 hemodilution.

Reduction of Oxygen-Carrying Capacity Weakens the  hemodilution med minskad viskositet effect of dextran on the lysability of ex vivo thrombi. Ann Surg 1975 effect of heparin and low molecular weight heparin  Certainly, hemodilution produces two contrary effects. Although decreasing the hematocrit lowers blood viscosity and thereby improves CBF, it also reduces the delivery of oxygen to normal and ischemic tissues. Like the reduction in viscosity, this latter effect can also explain the improvement in CBF. Blood loss varied substantially among patients, resulting in <1% to 14% decreases in hemostatic protein levels. On average, consumption because of activation resulted in less than a 1% drop in the concentration of coagulation and fibrinolytic factors during cardiopulmonary bypass.
