Results: (a) In prior studies using native plasma for hemodilution R0 averaged 50 +/- 8% of R0.45, while in studies using artificial solutions R0 averaged 32 +/- 12% of R0.45. The larger reduction of flow resistance upon dilution with artificial media is independent of viscosity and oncotic pressure. Other design characteristics did not show strong significant effects.

In addition to primary hematologic diseases, contributing factors include acute illness, phlebotomy and dilutional anemia. In fact, intravenous fluids are given to a majority of inpatients at some point during their hospitalization, and studies on fluid resuscitation in sepsis highlight the significant effect of hemodilution on anemia. Abstract. This study evaluates the effect of blood volume and hematocrit changes on brain tissue during temporary global ischemia. Normal saline was administered intravenously to 55 gerbils to achieve hypo-, normo-, and hypervolemic hemodilution and uniform 30% hematocrit reduction.

This study evaluates the effect of hemodilution by various common resuscitation fluids, and the efficacy of activated recombinant factor VII (rFVIIa) on coagulation parameters in human blood in vitro.Samples from normal healthy volunteers (n = 9) were hemodiluted from 0% to 90% with normal saline, or 0%, 40%, 60%, and 80% with 5% albumin, Hespan, Hextend, normal saline, or lactated Ringer's

Blood loss was the next most important resulting in an average 6% drop in factor levels during CPB, but the range was quite variable with some patients showing little change whereas others showed up to a 14% decrease in factor levels attributed to blood loss.

Clinically, the most noticeable effect of hemodilution is a marked reduction in the perfusion pressure at initiation of CPB. Gordon et al. showed that when hemodilution is used to decrease the hematocrit and when the flow rate on CPB is held constant, the perfusion pressure decreases in direct proportion to the change in viscosity . The potential impact of hemodilution on blood transfusions It is well established that iatrogenic hemodilution may lead to increased blood transfusion due to dilutional coagulopathy and increased surgical bleeding.

The larger reduction of flow resistance upon dilution with artificial media is independent of viscosity and oncotic pressure. 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.

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).

The initial results showed an improvement of visual acuity three months after isovolemic hemodilution in six of eleven patients in comparison to one of ten patients in the control group ( ) [ 20 ].

Hemodilution with dextran: Effects on blood flow and thrombus formation. The blood is diluted by overloading the vascular system [245]. After isovolemic bemodilution tbe dilution effect is more marked due to the pblebotomy.

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.
