Summary

The application of acute Normovolemic Hemodilution in cardiac surgery can effectively reduce perioperative blood transfusion, reduce postoperative complications and mortality, and is a low-cost, operable and effective blood protection measure.For the application of Acute Normovolemic Hemodilution in heart surgery, we still face an urgent problem: to what extent can Acute Normovolemic Hemodilution achieve better "blood saving effect", that is, whether a large number of Acute Normovolemic Hemodilution can reduce perioperative blood transfusion to a greater extent.

Conditions

  • Cardiac Valve Surgery

Interventions

PROCEDURE

Acute Normovolemic Hemodilution

Following induction of anesthesia, the volume of blood to be removed during Acute Normovolemic Hemodilution was calculated using an established formula:V=Weight（Kg）×12-15（mL/Kg）;Blood to be removed was capped at： Vmax=EVB×(Hi-Hf)/Hav（EBV= estimated blood volume （male:70mL/Kg，female:65mL/Kg）；Hi= initial hemoglobin ；Hf=target Hb（ 10g/dL ）；Hav= the average of the initial and minimal allowable hemoglobin）.Ensure the volume of removed blood does not exceed the upper limit and Hb ≥10g/dL after blood removed.
