NCT04210830

Brief Summary

Human Research Project Risk Category A. In this study no additional intervention or treatment are performed. The whole blood samples are taken from a routinely placed arterial catheter. The blood loss caused by the two additional blood samples is estimated with 2x 2.7ml. The Risk for the patients to participate in this study is minimal. Clinical observational study of a point of care in vitro diagnostic device, the Quantra®system (Quantra), that received the CE Mark in April 2017 and is approved by the Swiss Medic for clinical use. The Quantra estimates the coagulation strength of whole blood by sonorheometry technology applying a series of ultrasound pulses to a whole blood sample and measuring its stiffness by returning echoes.
