A Review of the Current Role of Blood Clotting Analyzers in Clinical Practice.

BACKGROUND: Viscoelastic tests (VETs) such as thromboelastography, rotational thromboelastography, and the Sonoclot Analyzer assess the entire process of clot formation through dissolution in real-time, and may provide additional therapeutic value to conventional laboratory coagulation tests. With the ability to obtain rapid results and identify specific coagulopathies, VETs has been examined in a variety of clinical scenarios, including cardiac surgery, trauma, obstetric emergencies, and liver transplant.
CONCLUSION: This review provides a summary of clinical trials utilizing VETs in the aforementioned clinical scenarios, and suggests that VETs have demonstrated a capability to identify coagulopathies, utility in guiding algorithms to reduce the amount of transfusions, and a limited ability to predict bleeding events or mortality.
