NCT04007484

Brief Summary

This study is a single-center, randomized, controlled, double-blind clinical trial. The main purpose of this study is to evaluate if hemoperfusion is sufficient to improve the prognosis of acute type A aortic dissection patients undergoing cardiopulmonary bypass and deep hypothermia circulatory arrest.

Study Arms (2)

HP+CPB/DHCA group

EXPERIMENTAL

For patients randomized into the intervention group, a hemoperfusion device will be connected in series to the extracorporeal circulation machine in advance to ensure that every single patient will undergo continuous hemoperfusion from the beginning to the end of CPB.

Device: Hemoperfusion

CPB/DHCA group

NO INTERVENTION

For patients randomized into the CPB/DHCA group, no hemoperfusion device will be connect to the extracorporeal circulation machine. Patients will undergo CPB and DHCA without continuous hemoperfusion.

Interventions

Hemoperfusion is achieved by blood filtration with a hemoperfusion device. Specifically, the hemoperfusion device composed of multiple parallel resin cartridges is connected in parallel to the oxygenator and blood reservoir and perfused at a rate of 200-250ml/min. The purpose of hemoperfusion is to decrease inflammatory mediators produced during cardiopulmonary bypass through resin cartridges adsorption, such as cytokines, free hemoglobin and other toxins. The ultimate goal of hemoperfusion is to decrease postoperative complications, improve postoperative recovery, and eventually shorten the length of hospital stay.
