Abstract Background— Anemia frequently occurs in chronic heart failure (CHF) patients and is associated with a poor prognosis. A low hematocrit may result from an increased plasma volume (hemodilution) or from reduced red blood cell volume (true anemia). The prevalence and clinical outcome of CHF patients with hemodilution is unknown.

2003;107:226-229.) Hemodilution caused a further reduction in Pbr (O (2)) in the TBI-anemia group relative to the TBI group without anemia (7.8 +/- 2.7 vs. 14.8 +/- 3.9 Torr, P < 0.05). The rCBF remained stable after TBI and increased comparably after hemodilution in both anemia and TBI-anemia groups. Hemodilution is defined as the reduction in concentration of normal blood constituents [49]. It is termed normovolemic when the volume of circulating blood is kept within normal limits. Anemia in heart failure (HF) is commonly diagnosed according to hemoglobin concentration [Hb], hence may be the result of hemodilution or true red blood cell volume (RBCV) deficit.

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.

During acute surgical blood loss, the adrenergic nervous system is stimulated, which leads to vasoconstriction and tachycardia. Keywords: Hemodilution, Anemia, Mean arterial pressure, Cardiac output, Hypotension, Partial pressure of oxygen in tissue Background The optimal care of critically ill patients often involves management of multiple risk factors for inadequate organ perfusion, including hypotension and anemia.

We hypothesized that the negative cardiovascular effects of anesthetic agents may exceed their effects on tissue metabolism, so that increasing the level of anesthesia may reduce tolerance to acute isovolemic anemia and increase the critical hemoglobin. We tested this hypothesis in a dog model of stepwise isovolemic hemodilution.

The destruction of red blood cells is called hemolysis. Red blood cells carry oxygen to all parts of your body. If you have a lower than normal amount of red blood cells, you have anemia. Thus during pregnancy, anemia is defined as hemoglobin (Hb) < 10 g/dL (Hct < 30%). If Hb is < 11.5 g/dL at the onset of pregnancy, women may be treated prophylactically because subsequent hemodilution usually reduces Hb to < 10 g/dL. Despite hemodilution, oxygen-carrying capacity remains normal throughout pregnancy.

3 reported that in approximately half the cases anemia can be explained as a result of hemodilution (increased plasma volume [PV]) rather than by a reduction in red cell mass (RCM), especially in chronic heart and liver diseases. These results, obtained by using total hemoglobin mass measurement with carbon Blood volume analysis can distinguish true anemia from hemodilution in critically ill patients Use of blood volume analysis in critically ill patients may help to distinguish true anemia from hemodilution, potentially preventing unnecessary interventions. In a recent study, Otto et al. 3 reported that in approximately half the cases anemia can be explained as a result of hemodilution (increased plasma volume [PV]) rather than by a reduction in red cell mass (RCM), especially in chronic heart and liver diseases.

Anemia is associated with a poor prognosis in CHF. Patients with hemodilution tend to do worse than patients with true anemia, which suggests that volume overload may be an important mechanism contributing to the poor outcome in anemic CHF patients. (Circulation. 2003;107:226-229.) Hemodilution caused a further reduction in Pbr (O (2)) in the TBI-anemia group relative to the TBI group without anemia (7.8 +/- 2.7 vs. 14.8 +/- 3.9 Torr, P < 0.05).
