Quantra versus Standard Hemostasis in Pediatric Cardiac Surgery: A Preliminary Study.

"QStat provides comparable information to the ROTEM delta and TEG 6s in trauma patients and can be useful for diagnosing TIC and guiding treatment. The Quantra's simplicity of use, ability to deploy at the POC, and rapid availability of results may provide clinicians with a faster, more convenient means to assess and manage TIC."

Comparison of the Point-Of-Care Coagulation Device Quantra With the TEG-5000 for Congenital Cardiac Surgery-A Pilot Study.

This study confirms that the Quantra System with the QStat Cartridge is a highly reliable alternative to the ROTEM delta for monitoring hemostasis during liver transplantation. Showing strong correlation and over 90% agreement in detecting fibrinolysis, the Quantra provides comparable clinical data through a faster, more user-friendly interface. Its point-of-care efficiency makes it a valuable tool for optimizing transfusion management in critical surgical settings.

While new cartridge-based VHA devices simplify point-of-care testing, their clinical value is not yet fully established. Current research highlights a lack of interchangeability between devices and a shortage of data linking them to patient outcomes or comparing them to rapid conventional assays. Consequently, despite their technical promise, robust randomized clinical trials are still required to prove their utility in critical care settings.

Modern cartridge-based VET - specifically the TEG 6s, HemoSonics Quantra, and ROTEM sigma - offers superior portability and ease of use compared to traditional laboratory methods. Despite limited randomized evidence for these new-generation devices, VET-guided algorithms effectively reduce blood product usage without compromising patient outcomes. Future validation of clinical cut-offs will be key to optimizing transfusion management.

"ROTEM sigma, TEG 6S, and Quantra performed similarly for exploring platelet count or residual circulating heparin. Thromboelastography 6S presented a weaker correlation with fibrinogen Clauss."
