QStat in Liver Transplant

2019-10-09 09:21:36 | BioPortfolio


This study will assess the clinical performance of the Quantra System with the QStat Cartridge in the liver transplant population.


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 propoerties of a whole blood sample during coagulation. The Quantra QStat Cartridge was developed to monitor hemostasis in the trauma and liver transplant populations which may experience a range of coagulopathies of various etiologies including fibrinolytic defects.

This single-center, prospective, observational stuey will evaluate the performance of the Quantra System with the QStat Cartridge as compared to corresponding measures determined using the TEG 5000.

Medical and Biotech [MESH] Definitions

Loss of blood during a surgical procedure.

Procedure in which arterial blood pressure is intentionally reduced in order to control blood loss during surgery. This procedure is performed either pharmacologically or by pre-surgical removal of blood.

Recovery of blood lost from surgical procedures for reuse by the same patient in AUTOLOGOUS BLOOD TRANSFUSIONS. It is collected during (intraoperatively) or after completion of (postoperatively) the surgical procedures.

Blocking of a blood vessel by air bubbles that enter the circulatory system, usually after TRAUMA; surgical procedures, or changes in atmospheric pressure.

Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
