Continuous Veno-Venous Hemofiltration ( CVVH ) machine or haemoperfusion machine ( Jafron Company ) if there was no need for renal replacement therapy ( RRT ). The only difference was the manufacturer-defined duration of adsorption : 6 h for HA 330 , and 24 h for Cytosorb .
Intraoperative HA was performed using a standard CPB roller pump ( Stockert S5 , LivaNova Deutschland GmbH ) with a mean arterial pressure of 68 – 84 mmHg and temperature control ( 35 ° C ). The HA 330 device was placed in the CPB venous circuit ( Figure 1 ), using a haemoperfusion machine . The blood flow rate on the haemoperfusion machine was 160 – 200 ml / min . The Cytosorb cartridge was placed in the CPB without a haemoperfusion machine with an inflow arterial line and returned to the venous line .
