The purpose of this study is to evaluate the clinical utility of thrombelastography (TEG) to predict and identify trauma patients at increased risk of receiving blood transfusion, develop multiple organ failure and mortality.

TEG has been proposed as a superior tool to rapidly diagnose and help guide resuscitation with blood products and preclinical data suggest that TEG is both more sensitive and specific than PT or PTT for coagulation abnormalities. Based on the preclinical work led by Dr. Holcomb, our hypothesis is that the Rapid TEG will help to identify these coagulopathic patients earlier, allow for rapid MT protocol activation, and assist in developing data driven blood product transfusion guidelines.

Condition Intervention

Further study details as provided by The University of Texas Health Science Center, Houston:

Primary Outcome Measures:
  • To determine the prevalence and severity of immediate disturbances in coagulation by both RapidTEG and conventional coagulation parameters among major trauma activations. [ Time Frame: First 5 days of hospitalization ]

Secondary Outcome Measures:
  • To determine if there are specific abnormalities of RapidTEG that correlate with specific early blood product utilization. [ Time Frame: First 5 days of hospitalization ]
  • To determine if RapidTEG abnormalities, when compared to kaolin-activated TEG, PT, INR and aPTT, correlate with patient outcomes in severely injured patients. [ Time Frame: First 5 days of hospitalization ]
  • To determine the temporal relationship between rapid TEG parameters and anatomic injury, mechanism of injury, and severity of injury. [ Time Frame: First 5 days of hospitalization ]

Groups/Cohorts Assigned Interventions
Adult trauma patients
Patients admitted to the emergency department (ED) as the highest level of acuity following a traumatic injury at three Level 1 trauma centers in the United States (UT Houston, UC San Francisco, Oregon Health Center).
Procedure: RapidTEG test
The RapidTEG test will be done at the study time points (3, 6, 12, 24 hours and 4 addiitonal days).
