Overview

Randomized trial demonstrates that TEG-guided transfusion reduces blood product use in complex cardiac surgery, suggesting point-of-care monitoring improves targeted hemostasis.

Key Points

To evaluate whether a point-of-care thromboelastography (TEG)-guided transfusion algorithm reduces blood product requirements compared with routine transfusion therapy in patients undergoing complex cardiac surgery.
Conducted a prospective, randomized, blinded clinical trial enrolling cardiac surgical patients at moderate to high risk of transfusion after cardiopulmonary bypass.
Randomly assigned patients to either a TEG-guided transfusion algorithm (n = 53) or routine transfusion therapy (n = 52), with all patients receiving prophylactic antifibrinolytic therapy.
Evaluated transfusion volumes, specific blood components, coagulation test variables, and mediastinal chest tube drainage at serial postoperative intervals.
Significantly fewer patients required fresh-frozen plasma in the TEG group (4 of 53 [7.5%]) compared with the control group (16 of 52 [30.8%]; P < 0.002).
Platelet transfusions were administered to fewer patients in the TEG arm (7 of 53 [13.2%]) than in the control arm (15 of 52 [28.8%]; P < 0.05), and TEG patients received less fresh-frozen plasma volume (36 ± 142 mL vs 217 ± 463 mL; P < 0.04).
Mediastinal tube drainage did not significantly differ between groups at 6, 12, or 24 hours postoperatively, and intraoperative transfusion rates were similar.
