To specifically assess the intrinsic effect of plasma substitute molecules on blood coagulation as opposed to a dilutional effect, hemodilution with lactated Ringer’s solution was first analyzed . At 10:10 hemodilution ratio, compared with baseline values, K increased and MA decreased in statistical significance.

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. Effect of albumin and mannitol on organ blood flow, oxygen delivery, water content, and renal function during hypothermic hemodilution cardiopulmonary bypass. Ann Thorac Surg 1982 ; 33: 250 – 257 . This was related to a marked blunting of the cardiac output response to hemodilution in the animals receiving the higher anesthetic dosage.

Aim To re-evaluate currently use hemodilution algorithm 48 hrs prior to consent/blood draw. Background and Purpose To evaluate the effects of hemodilution on cerebral hemodynamics and oxygen metabolism in the normal human brain, we measured regional cerebral blood flow, oxygen extraction fraction, oxygen metabolic rate, and regional cerebral blood volume in eight normal volunteers before and after hemodilution using positron emission tomography and oxygen-15–labeled gas inhalation Briden KL, Teltzer M, Weiss HR (1979) The effect of mild normovolemic hemodilution on regional flow, oxygenation an small vessel blood content in the rabbit heart subjected to acute coronary occlusion.

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.

Hemodilution. The dilutional effects of fluid administration on the coagulation system are proportionate to the degree of hemodilution. The effects include decreasing platelet number, but not function, and decreasing procoagulant and anticoagulant [e.g., antithrombin (AT)] proteins to varying degrees . The effect of hemodilution is often not

The dilutional effects of fluid administration on the coagulation system are proportionate to the degree of hemodilution. The effects include decreasing platelet number, but not function, and decreasing procoagulant and anticoagulant [e.g., antithrombin (AT)] proteins to varying degrees . The effect of hemodilution is often not In settings requiring rapid transfusion of RBC units, needleless connectors should not be used and hemodilution should be considered in order to decrease the time required to deliver an equivalent red cell mass.

The effect of hemodilution during normothermic cardiac surgery on renal physiology and function: a review Although the definitions of renal dysfunction vary, loss of renal function is a common complication following cardiac surgery using cardiopulmonary bypass (CPB).

We sought to determine whether maintenance or bolus fluid therapy causes a significant change in the hematocrit and other hematologic parameters included in the complete blood count. Nine subjects completed a randomized three-period crossover designed trial in which they were given no fluid, maintenance fluid, or a bolus of fluid followed by maintenance fluid. 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. 2526 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.

Iatrogenic hemodilution: a possible cause for avoidable blood transfusions? The effect of fluid administration on the hemoglobin concentration. Fluid administration may result in a beneficial The potential impact of hemodilution on blood transfusions.

There was no difference in hemoglobin or hematocrit during the no fluid or maintenance fluid treatments. No significant changes occurred in white blood cell or platelet counts. The effect of isovolemic hemodilution on the circulation of red blood cells (RBCs) in the cerebrocortical capillary network was studied by intravital videomicroscopy with use of a closed-cranial-wi Effect of hemodilution on RBC velocity, supply rate, and hematocrit in the cerebral capillary network | Journal of Applied Physiology However, if the hemodilution is preceded by heparinase treatment of the microvessels , the value of R 0/0.45 (0.65±0.14) is close to the mean value (0.59±0.08) for the ‘plasma’ class and to predictions based on glass tube rheology (0.62±0.015), suggesting that only the red cell dependent effect of hemodilution is present. Hemodilution innebär att blodet spädes ut, dvs koncentrationen av blodkroppar minskar.

Abstract. The effects of intravenous fluids on hematocrit are debated. We sought to determine whether maintenance or bolus fluid therapy causes a significant change in the hematocrit and other hematologic parameters included in the complete blood count. Nine subjects completed a randomized three-period crossover designed trial in which they were given no fluid, maintenance fluid, or a bolus of fluid followed by maintenance fluid. 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. 2526 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.
