Table 4 Comparison between ECMO and CPB
ECMO | CPB | |
|---|---|---|
Pump | Centrifugal | Roller |
Heparinization | 50–100 units/kg | 200–300 units/kg |
Circuit type | Opened | Closed |
Maximal possible time of circulation | Weeks (Veno-venous, as a bridge to LuTx or post LuTx) | Hours |
Ischemia of lower limbs | Common (peripheral ECMO) | Rare |
Bleeding complications | Less frequent | More frequent |
Primary graft dysfunction (PGD) | Less often | More often |
Activated clotting time (ACT) necessary | 150–170 s | > 400 s |
Reservoir | Absent | Present |
Open air contact | Absent | Present |
