Use of Nafamostat Mesilate for Anticoagulation in Patients With ECMO

Use of Nafamostat Mesilate for Anticoagulation in Patients With Extracorporeal Membrane Oxygenation After Cardiac Surgery: Efficacy and Safety

The purpose of this study is to evaluate the effectiveness and safety of nafamostat mesilate compared with unfractionated heparin for anticoagulation in patients with ECMO after cardiac surgery.

Selecting patients who require systemic anticoagulation as the study subjects from patients undergoing extracorporeal membrane oxygenation assistance after cardiac surgery. Randomly divided into the nafamostat mesilate group and unfractionated heparin group. To evaluate the efficacy and safety of nafamostat mesilate by comparing the incidence of bleeding and thrombosis within the target anticoagulant level range between two groups of patients during ECMO

4. Severe liver insufficiency
5. Connective tissue disease
6. There is a history of allergy to heparin or nemolastat mesylate.
