PurposeThe purpose of this study was to determine if thromboelastography (TEG) is associated with reduced blood product utilization for trauma patients undergoing massive transfusion protocol (MTP) compared to traditional coagulation tests.MethodsA retrospective review was conducted on an intent-to-treat basis of trauma patients undergoing MTP (Pre-TEG = Period I vs. Post-TEG = Period II). Traditional coagulation tests guided transfusion during Period I (n = 20) and the intent was that TEG guided transfusions during Period II (n = 47). Blood product administration and outcomes were compared.ResultsIntent-to-treat analysis demonstrated a significant reduction in red blood cell transfusions (11 vs. 6 units, P = 0.001), number of patients receiving fresh frozen plasma (85.0 vs. 17.0%, P < 0.001), and platelets (75.0 vs. 38.3%, P = 0.006) in Period II. No difference was seen between Periods I and II in ICU days (7.0 vs. 11.0 days, P = 0.073), hospital length of stay (10.5 vs. 14.0 days, P = 0.618), or mortality (55.0 vs. 31.9%, P = 0.076).ConclusionUse of TEG-guided transfusion in the critically-ill trauma patient conserved blood product utilization and appears to offer similar outcomes when compared to traditional coagulation tests.Copyright © 2019.
