the Efficacy and Safety of New Anticoagulation Strategies of Maintain Normal Clot Rate to Prevent Hemorrhage While VV-ECMO

Effective and normative anticoagulation is one of the most important components of Extracorporeal membrane oxygenation (ECMO) management. Excessive anticoagulation may lead to hemorrhage, which is the most common and serious complication. Currently, the most common factors for monitoring anticoagulation of ECMO are the activated clotting time (ACT) and activated partial thromboplastin time (APTT). However, there is a lack of a unified understanding of the related monitoring measures, monitoring targets, and bleeding risk assessments, which have been chosen mainly because of experiences reported by various ECMO centers or the results of retrospective studies.Therefore, anticoagulation strategies need to be improved. Our research have found ECMO anticoagulation management should be transformed from monitoring only the APTT/activated clotting time (ACT) to considering the entire coagulation process. To maintain thrombosis ability and PLT function within normal ranges may help reduce hemorrhage rates and improve prognoses. This randomized controlled study aim to develop the safety and efficacy new anticoagulation strategies of VV-ECMO.
