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. 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.

Hemodilution effect

Although early animal studies indicated a potential benefit to hemodilution, strengthening the belief that hemodilution during cardiac surgery was without consequence, 13,14 most of these studies were limited in that they did not mimic CPB or reduce hematocrit below 30%. Abstract. Objective: Hemodilution has been associated with both hypocoagulability and hypercoagulability in studies based on thromboelastography (TEG). Severe hemodilution during cardiopulmonary bypass (CPB) is a risk factor for morbidity in cardiac surgery. This study investigated the effects of different degrees of hemodilution with CPB on post-CPB TEG parameters and coagulation-related outcomes. Hemodilution has the largest effect on drugs whose distribution is primarily confined to the bloodstream.

METHODOLOGY: Forty ASA I-II patients undergoing acute laparotomy were randomly divided into 2 groups (n=20 each): Patients of group A received Voluven 7 ml/kg in 20 mins before induction and 8 ml Effect of Hemodilution In Vitro with Hydroxyethyl Starch on Hemostasis May 2017 Medical Science Monitor: International Medical Journal of Experimental and Clinical Research 23:2189-2197 Our results show that hemodilution has an important effect on the oxygen consumption and delivery in rodents, which varies on whether the animal is at sea level or at 2,600 m above sea level. Additionally, the PFCOC performed differently in the two places, transporting and delivering more oxygen at sea level and becoming a more significant source of oxygen than at 2,600 m.

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. Anemia amongst hospitalized patients is widespread, occurring in up to 75% of inpatients.

CONCLUSIONS: Increased anesthetic depth with halothane or ketamine resulted in a decreased tolerance to acute anemia, as reflected by a significant increase in critical hemoglobin concentration. PMID: 12826848 Hemodilution reduces the need for blood transfusion and hereby the risk for transmission of infectious agents. The present study investigated effects on systemic and myocardial circulation and oxygenation, and blood lactate concentrations; induced by nitrous oxide, isoflurane, hypoxia, and uncompensated blood loss, in pigs hemodiluted to a hematocrit of 11%. In both groups the change in blood flow velocities is comparable.

On average, consumption because of activation resulted in less than a 1% drop in the concentration of coagulation and fibrinolytic factors during cardiopulmonary bypass.

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.
