A Comparison of a New Ultrasound-Based Whole Blood Viscoelastic Test (SEER Sonorheometry) Versus Thromboelastography in Cardiac Surgery

摘要

BACKGROUND: Viscoelastic thromboelastography tests such as TEG (TM) are now routine for assessing the coagulation status of cardiac surgery patients. We compared TEG (TM) with a new technology, sonic estimation of elasticity via resonance (SEER) sonorheometry, to compare measures of coagulation dynamics of whole blood and assess its potential for rapid, near-point-of-care monitoring of hemostasis during cardiac surgery.
