    Trauma patients often have coagulation defects, impacting treatment. A simple tube-clot test can quickly assess blood coagulation in trauma patients before lab results are available.

    Area of Science:

    • Trauma care
    • Hematology
    • Surgical complications

    Background:

    • Coagulation abnormalities present significant risks for hemorrhaging patients and surgical interventions.
    • A high prevalence of coagulation defects was observed in trauma fatalities prior to treatment.

    Purpose of the Study:

    • To investigate the incidence and characteristics of coagulation defects in trauma patients.
    • To evaluate the potential of the tube-clot test as a rapid diagnostic tool for coagulation status in trauma.

    Main Methods:

    • Retrospective analysis of 180 trauma patients who died.
    • Review of coagulation test results including prothrombin time, platelet count, and partial thromboplastin time.
    • Clinical observation of bleeding and hematoma formation.

    Main Results:

    • 97.2% of deceased trauma patients exhibited coagulation defects before treatment.
    • Significant abnormalities were noted in prothrombin time (97%), platelet count (72%), and partial thromboplastin time (70%).
    • Head trauma patients showed the most severe coagulation abnormalities.

    Conclusions:

    • The high incidence suggests disseminated intravascular coagulation as a likely cause of pre-treatment coagulopathy.
    • The tube-clot test offers a rapid, practical method for assessing coagulation in trauma patients awaiting definitive laboratory results.
