Monitoring Anticoagulation in Patients on ECMO for Severe Lung Failure
Study Details
Study Description
Brief Summary
A monocentric observational study evaluates the accuracy of anticoagulation monitoring in critically ill patients on ECLS (extracorporeal life support) using new markers of the effect of direct thrombin inhibitors and also the accuracy of anticoagulation monitoring in patients on unfractionated heparin using anti-Xa. A more accurate setting of anticoagulation may lead to a reduction in the number of serious bleeding and thrombotic complications in these patients.

Detailed Description
Anticoagulation using a direct thrombin inhibitor, argatroban, is one of the modern options for anticoagulation in patients on VV (veno-venous) ECMO (extracorporeal membrane oxygenation) support, and in 2021 the ECMO center of the University Hospital Ostrava changed the standard anticoagulation using UHF (unfractionated heparin) to anticoagulation using Argatroban as a new standard of routine care. Argatroban shows more stable levels and has a short half-life, and a number of foreign ECMO centers have been using Argatroban for a long time also as basic anticoagulation in all ECMO patients.
To monitor the effect of direct thrombin inhibitors, it is possible to use monitoring of anti-FIIa activity, which directly assesses the effect of the anticoagulant on thrombin activity. Anticoagulation with Argatroban may reduce the risk of serious bleeding complications. Target values of aPTT (Activated Partial Thromboplastin Time) and anti-FIIa can be determined according to ELSO (Extracorporeal Life Support Organization) guidelines.
