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 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...
متن کاملPreoperative acute hypervolemic hemodilution with hydroxyethylstarch: an alternative to acute normovolemic hemodilution?
Acute normovolemic hemodilution (ANH) may help to reduce demand for homologous blood but requires extra time and apparatus. A more simple procedure is acute hypervolemic hemodilution (HHD), where hydroxyethylstarch is administered preoperatively without removal of blood. In a prospectively randomized study we compared ANH (preoperatively 15 mL/kg autologous blood removal and replacement with 15...
متن کاملAcute normovolemic hemodilution in children submitted to posterior spinal fusion.
BACKGROUND AND OBJECTIVES Acute Normovolemic Hemodilution (ANH) is a simple and low-cost autologous transfusion method. This study aimed at evaluating whether ANH is able to decrease homologous transfusions in children undergoing posterior spinal fusion and at verifying hemodilution-induced complications in those patients. METHODS Participated in this study 25 children, physical status ASA I ...
