April 13, 2023 updated by: Litao Zhang, Wuhan Asia Heart Hospital
D-dimer to Improve Anticoagulation Management in Adult Patients Supported With Extracorporeal Membrane Oxygenation: a Prospective Cohort Study
This was a prospective, cohort study.
Study Overview
Status
Active, not recruiting
Intervention / Treatment
Detailed Description
Adult Patients receiving ECMO surpport in Wuhan Asia Heart Hospital were enrolled by cohort.
Unfractionated heparin was used for Anticoagulation therapy, APTT or Anti-Xa activity is monitored for dose adjustment.
Meanwhile, D-dimer is mornitored.
If D-dimer levels continue to rise (>1.5 times previous result ), increase the dose of heparin to reach the upper limit of the treatment target; If the D-dimer levels is stable (<1.5 times previous result ) or is decreasing, the anticoagulation dose is maintained at current level (no active bleeding) or decreased (active bleeding).
All patients were followed up The occurrence of endpoints during in-hospital and 30 days after discharge, including bleeding events, thrombotic events and all-cause deaths were recorded.

D-dimer and anti-Xa are mornitored.
If D-dimer levels continue to rise (>1.5 times previous result ), increase the dose of heparin to reach the upper limit of the treatment target; If the D-dimer levels is stable (<1.5 times previous result ) or is decreasing, the anticoagulation dose is maintained at current level (no active bleeding) or decreased (active bleeding).

Active Comparator: Control group
Heparin dose adjusted according to anti-Xa activity or activated partial thromboplastin time (aPTT).
The target range is aPTT 1.5 to 2.5 times the upper limit of normal or therapeutic anti-Xa levels (0.3 U/ml to 0.7 U/ml) for unfractionated heparin.

0.3-0.7U/ml of anti-Xa activity or APTT 1.5-2.5 times of control
