Hemodynamic compensation during acute normovolemic hemodilution.
To the Editor:—Acute normovolemic hemodilution (ANH) causes a reduction in arterial oxygen content because of reduced hemoglobin concentration. The primary compensatory mechanism during ANH is an increase in cardiac output to maintain systemic oxygen delivery. Therefore, the lower limit of an acceptable hemoglobin concentration is related to how low hemoglobin can be reduced without jeopardizin...

متن کاملAcute decrease in renal microvascular PO2 during acute normovolemic hemodilution.
Large differences in the tolerance of organ systems to conditions of decreased O(2) delivery such as hemodilution exist. The kidney receives approximately 25% of the cardiac output and O(2) delivery is in excess of the oxygen demand under normal circumstances. In a rat model of acute normovolemic hemodilution (ANH), we studied the effect of reduced hematocrit on renal regional and microvascular...

COVID-19 pandemic has imposed adverse economic consequences on the whole population. This is while the elderly and those with comorbidities, the economically disadvantaged and ethnic minorities were at increased risk of viral infection. Moreover, the mortality rate an...
متن کاملAcute Normovolemic Hemodilution: A Practical Approach
Justifications: Perioperative allogeneic blood transfusion can be reduced or even completely avoided by using a set of different strategies: meticulous hemostasis, the use of pharmaceutical agents that assist in the process of coagulation/ fibrinolysis, the use of blood substitutes, induced hypotension, preoperative autologous blood donation, collection and reinfusion of autologous blood during...
