Transfusion Threshold of Hemoglobin 80 g/L Is Comparable to 100 g/L in Terms of Bleeding in Cardiac Surgery: A Prospective Randomized Study

摘要

Objective: Anemia is common after cardiac surgery and, according to some suggestive evidence, may be associated with increased bleeding, other morbidity, and mortality. However, transfusion of red blood cells (RBC) may cause adverse effects and increase cost. The authors hypothesized that the restrictive hemoglobin threshold (Hb of 80 g/L) may aggravate bleeding more than the higher Hb threshold (Hb 100 g/L).
