Bleeding Clinical Trial
— CASUAL-ECMOOfficial title:
A Three-arm Randomized Controlled Non-inferiority Pilot Study Comparing Anticoagulation Strategies Using Unfractionated Heparin, Argatroban and Low-molecular-weight Heparin for Extracorporeal Membrane Oxygenation Support
A three-arm randomized controlled non-inferiority pilot study comparing anticoagulation strategies using unfractionated heparin, argatroban and enoxaparin for extracorporeal membrane oxygenation support conducted as an investigator-initiated, prospective, parallel group, open-label, active comparator controlled, single center, phase IV study to evaluate the non-inferiority of enoxaparin or argatroban for anticoagulation during ECMO therapy in comparison to the current standard, unfractionated heparin, as measured by the incidence of thromboembolic events during the duration of ECMO therapy
