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 The pathogenesis of anemia in CHF is multifactorial. In our study, the incidence of hemodilution was extremely common, occurring in 46% of the anemic patients. Identification of patients with true anemia selects patients who require further diagnostic work-up and treatment of their anemia. CHF patients with hemodilution may simply require an After hemodilution, there was a small increase in the MAP and CVP, relative to baseline, immediately following hemodilution, in both the anemia and TBI-anemia groups (Fig. 2, P < 0.05).

Hemodilution anemia

Over the past two decades, clinical trends have led to progressive reductions in the acceptable hemoglobin threshold. This has resulted in an increased incidence of acute hemodilution due to transfusion avoidance and an increase in the degree of non-blood fluid resuscitation. 1975-06-01 · An understanding of the physiology involved in hemodilution aids the physician to understand the adaptive response to blood loss. As the hematocrit and viscosity decrease, the flow through the microcirculation increases within certain limits if the cardiac function is adequate. Various mechanisms have been proposed to explain the origin of anemia in trypanosomiasis, these include suppression of erythropoietic activity due to bone marrow depression, hemodilution, hemolysis resulting from immunological factors, direct parasite action and the products released by parasites. Conclusion—Hemodilution is common in CHF patients. 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.

Tolerance to severe anemia could also be improved by hyperoxic ventilation and -Extreme hemodilution reduces oxygen delivery to the body and will, hence, decrease the tolerance to challenges with increased oxygen demand such as shivering.-Cooling is modestly protective during severe anemia. Following hemodilution, the hemoglobin concentration in the anemia and TBI-anemia groups decreased comparably to minimum values of 56 ± 15 and 52 ± 13 g/l, respectively (Table 1, P < 0.05). The blood oxygen content was also reduced to a similar level in both groups. the spleen. Instead, anemia results from an increase in blood volume (hemodilution).

Hemodilution has not been associated with systemic or cardiac markers of inadequate oxygenation in patients undergoing coronary artery surgery. 22,23The coronary vasculature has a reserve dilatory capacity, which, in response to acute anemia, can increase blood flow by several fold.

compared with nHct, diagnosed anemia (Hct 30) nearly equal within the hypovolemic and normovolemic groups. However, pHct overdiagnosed anemia in 46.7% of hypervolemic patients. Conclusion: Use of blood volume analysis in critically ill patients may help to distinguish true anemia from hemodilution, potentially preventing unnec-essary interventions.
