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 کاملAcute normovolemic hemodilution improves oxygenation in ischemic flap tissue.
BACKGROUND The flaps used in reconstructive surgery are prone to ischemia and hypoxia, which imply a considerable risk of wound-healing complications. During normovolemic hemodilution, the oxygenation may further deteriorate because of the lack of erythrocytes or improve because of increased microcirculatory blood flow. The aim of this study was to investigate the net effect of normovolemic hem...
متن کاملImpact of Acute Normovolemic Hemodilution in Organ and Cell Structure
Rigorous control procedures adopted presently by blood banks have reduced transfusionassociated risks, such as transmission of infectious diseases. Nevertheless, other complications related with blood-transfusions remain, such as transfusion-related acute lung injury (TRALI) and other immune disorders. In critically ill patients, transfusion has been associated with increase in morbidity and mo...
