An overview of thrombelastography research
Introduction: Thrombelastography (TEG) is a method to assess clot formation and destruction. Various applications have been suggested in the literature.
Objective: To provide an overview of the current knowledge about TEG applications.
Methods: Adatabase search in PubMedwas performed up to July 2012 using the term "Thrombelastography [MeSH Terms]". We analysed retrospective and prospective studies, reviews and guidelines with information about the applications of TEG written in English and Spanish.
Results: The search resulted in 3139 papers since 1962. These were classified in 8 categories: 862 (27.6%) in non-surgical diseases, 294 (9.4%) in liver transplant, 711 (22.6%) in basic research, 174 (5.5%) in obstetrics, 228 (7.3%) in cardiovascular surgery, 177 (5.6%) in other types of surgery, 234 (7.4%) in anaesthetic techniques, and 459 (14.6%) in relation with medications.
Conclusion: The application of TEG as a diagnostic tool and as a guide in transfusion therapy is increasing. Its use is still in development in different clinical fields and the advantages and limitations of this technique still have to be defined. It is evident that thrombelastography should be used with caution, and its strengths and weaknesses as well as new applications must continue to be explored.
