NCT01021631

Brief Summary

Blood transfusion is related to worse outcomes and the triggers for red blood cells transfusion are not well defined in cardiac surgery. Retrospective studies in cardiac surgery do not show benefits of red blood cell transfusion in reduction of morbidity and mortality in cardiac surgery. There are no prospective studies comparing outcomes between restrictive or liberal strategy in cardiac surgery.This study is a double-blind randomized study comparing clinical outcomes between two strategies of transfusion in cardiac surgery - liberal or restrictive.

Outcome Measures

Primary Outcomes (1)

  • The primary purpose of this study is to compare clinical outcomes after cardiac surgery in patients submitted to different strategies of red blood cell transfusion

    30 days after surgery

Secondary Outcomes (1)

  • To compare length of stay in ICU, length of stay in Hospital, health-related quality of life, hospital costs and mortality between groups.

    3 months

Study Arms (2)

Liberal Transfusion Strategy

ACTIVE COMPARATOR

Liberal Group - transfusion when hematocrit is lower than 30%

Other: Red blood cell transfusion

Restrictive Transfusion Strategy

ACTIVE COMPARATOR

Restrictive Group - transfusion when hematocrit is lower than 24%

Other: Red blood cell transfusion

Interventions

Red blood cell (RBC) transfusion will be given when hematocrit fall below 30% since intraoperative until the discharge of intensive care unit. Following administration of the 1 RBC unit, a repeat hematocrit is performed;if a patient's hematocrit is 30% or higher, no additional transfusion is necessary.
