Brief summary

The purpose of this study was to compare the efficacy and safety of nafamostat mesylate and unfractionated heparin during ECMO anticoagulation in critically ill patients.

Detailed description

During ECMO treatment, nafamostat mesylate and unfractionated heparin were randomly administered for continuous anticoagulation, respectively, and the incidence of bleeding and thrombotic complications during anticoagulation was compared between the two groups.

Interventions

ECMO patients were given continuous anticoagulation with nafamostat mesylate, coagulation function was monitored every 6 hours, and APTT was maintained at 1-1.75 times the upper limit of normal detection until reaching the study endpoints, including 14 days after enrollment, 24 hours after withdrawal from ECMO, or any switch to ECMO mode during ECMO treatment.

DRUGUnfractionated Heparin

ECMO patients were given continuous anticoagulation with unfractionated heparin, coagulation function was monitored every 6 hours, and APTT was maintained at 1-1.75 times the upper limit of normal detection until reaching the study endpoints, including 14 days after enrollment, 24 hours after withdrawal from ECMO, or any switch to ECMO mode during ECMO treatment.

Inclusion criteria

* Patients aged \>= 18 and \<= 80 years; * Successfully established ECMO (VA/VV) treatment by percutaneous puncture due to cardiogenic shock or respiratory failure; * Anticoagulation required during ECMO treatment; Before the establishment of ECMO, the APTT test value was within the normal range, and the platelets were not less than 80G/L; * Within 48 hours of ECMO establishment, APTT test results were between 1 and 1.75 times the upper limit of normal, PLT\>80 G/L, and no serious bleeding and thrombosis; * Sign the informed consent.

Exclusion criteria
