Application of Large Volume Acute Normovolemic Hemodilution in Cardiac Surgery

Not Applicable

Completed

• Conditions: Cardiac Surgery; Acute Normovolemic Hemodilution
• Interventions: Procedure: Large volume Acute Normovolemic Hemodilution

• Registration Number: NCT04369443
• Lead Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University

Brief 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
