Registration Number
NCT03754868

University Hospital Goettingen
Brief Summary

Hemorrhagic and thromboembolic complications are common in Veno-venous ECMO therapy. The aim of this study is to provide a detailed analysis of the activity of different coagulation factors and changes in functional coagulation measurements as in rotational thrombelastometry and multiple electrode aggregometry in the course of ECMO therapy.
