Rotational thromboelastometry (ROTEM) parameters, specifically FIBTEM and EXTEM, reliably predict mid-term platelet transfusions in trauma patients. These tests correlate with conventional coagulation markers, aiding transfusion guidance.
Area of Science:
- Coagulation diagnostics
- Trauma patient management
- Transfusion medicine
Background:
- Rotational thromboelastometry (ROTEM) is a global coagulation test used in guiding platelet transfusions for trauma patients.
- Predicting the need for mid-term platelet transfusions in trauma patients is crucial for effective management.
Purpose of the Study:
- To evaluate the predictive capability of ROTEM parameters for mid-term (five-day) platelet transfusion requirements in trauma patients.
- To assess the correlation of ROTEM parameters with conventional coagulation tests.
Main Methods:
- Retrospective analysis of ROTEM parameters (FIBTEM, EXTEM, PLTEM) from 82 hospitalized trauma patients post-resuscitation.
- Maximum clot firmness and clot amplitudes (A5, A10, A15) were analyzed.
- Platelet transfusion data was reviewed for five days post-ROTEM analysis.
Main Results:
- FIBTEM and EXTEM demonstrated high predictive accuracy (AUC 0.915-0.923 and 0.878-0.896, respectively) for predicting >12 U platelet concentrate transfusion.
- PLTEM showed moderate predictive value (AUC 0.551-0.735).
- Strong correlations were observed between platelet count and EXTEM/PLTEM, platelet function and EXTEM, and fibrinogen levels and FIBTEM parameters.
Conclusions:
- FIBTEM and EXTEM are reliable tools for predicting mid-term platelet transfusion needs in trauma patients.
- ROTEM parameters correlate with conventional coagulation tests, including platelet counts and fibrinogen levels.
