Blood Loss, Surgical Clinical Trial
Official title:
Pre-surgical Evaluation for the Quantra System in Adult Patients Undergoing Cardiac Surgery
This study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the QPlus Cartridge in patients taking anitplatelet medication that are scheduled to undergo cardiac surgery.
The Quantra System is a fully integrated and automated in vitro diagnostic device which uses
SEER Sonorheometry, an ultrasound-based technology, to characterize the viscoelastic
properties of a whole blood sample during coagulation. The Quantra QPlus Cartridge was
developed to monitor hemostasis during major surgical procedures in adult patients. The
cartridge consists of four independent channels each containing different sets of reagents,
which provide four measurements performed in parallel yielding six parameters that depict the
functional status of a patient's coagulation system.
This single-site, prospective, observational study will evaluate the performance of the
Quantra System as compared to standard coagulation tests and comparable measures determined
using TEG in patients taking antiplatelet medication that are scheduled to undergo cardiac
surgery.
