OBJECTIVES: To describe the adjunctive use of thromboelastography (TEG) in directing initial blood component therapy resuscitation of patients with polytrauma with acute pelvic/acetabular fractures. DESIGN: Retrospective cohort review. SETTING: Level-2 trauma center. PATIENTS: Forty adult trauma activations with acute pelvic and/or acetabular fractures were treated with standard fracture care and TEG with adjuvant platelet mapping (TEG/PM) analysis to guide their initial 24-hour resuscitation. INTERVENTION: TEG with PM provided goal-directed hemostatic resuscitation using component blood products and an established hospital transfusion protocol. Transfusions were triggered by abnormal TEG/PM results and/or the presence of active hemorrhage, persistent hemorrhagic shock, and abnormal base deficit levels. MAIN OUTCOME MEASUREMENT: The correction of trauma-induced coagulopathy was determined by the return of a normal TEG/PM tracing. The numbers of component blood products transfused in the first 24 hours using TEG/PM were calculated. Subgroup analysis of transfusion requirements and differences between pelvic ring and acetabular fracture patterns were determined. RESULTS: More than 90% of patients received a transfusion of at least 1 blood product with 84% of transfusions occurring within 6 hours of admission. TEG/PM-guided resuscitation yielded greater volumes of platelets and packed red blood cells (PRBCs) versus fresh frozen plasma (FFP) (P = 0.018) with an average transfusion ratio of 2.5:1:2.8 (PRBC:FFP:platelet). There was a trend toward greater transfusion requirements in combined injuries versus pelvic ring or acetabular fractures (P = 0.08). CONCLUSION: TEG with PM is a valuable adjunct to guide the acute phase of resuscitation in patients with polytrauma with pelvic injuries because it allows a real-time assessment of the coagulation status. The routine use of TEG/PM may result in transfusion ratios of blood products different from those of the current empiric 1:1:1 guidelines. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
