Charlottesville, VA – December 6, 2016– HemoSonics today announced the upcoming presentation of data at the Post Graduate Assembly in Anesthesiology (PGA) Meeting demonstrating the potential of the Quantra™ Hemostasis Analyzer to aid clinicians in identifying the need for transfusion of allogeneic blood products in major spine surgery. The conference will be held in New York, NY December 9 – 13, 2016.
The reported study was conducted at the University of Virginia in Charlottesville, VA and compared results obtained with a research version of the Quantra™ Hemostasis Analyzer to equivalent rotational thromboelastometery (ROTEM™) and conventional laboratory parameters.
The abstract “Predicting Cryoprecipitate and Platelet Transfusion During Major Spine Surgery with SEER Sonorheometry versus Rotational Thromboelastometry” authored by Dr. Bhiken Naik, Dr. Marcel Durieux, and Dr. Edward Nemergut, all faculty in the Department of Anesthesiology at the University of Virginia, showed significant differences in the Quantra measurements of Clot Stiffness, Platelet Contribution and Fibrinogen Contribution between the patients that received a transfusion and those that did not. The area under the Receiver Operative Curves (ROC), a measure of the performance of a diagnostic test, for Fibrinogen Contribution versus cryoprecipitate transfusion, Clot Stiffness versus cryoprecipitate-platelet transfusion, and Platelet Contribution versus platelet transfusions were 0.8, 0.79, and 0.8, respectively. These data indicate that the Quantra and SEER Sonorheometry may provide clinically relevant measurements that could be utilized to aid in the management of perioperative bleeding.
