Objectives:
To investigate the impact of a cytokine haemoadsorption (HA) device (CytoSorb®) on inflammatory markers and patients' outcome during aortic root surgery.
Methods:
Prospective, observational study including all-comers with quasi-randomization by strictly alternating inclusion (1:1 basis). Sixty patients undergoing elective aortic surgery were assigned to either HA group (n = 30) with intraoperative HA, or a control (C) group (n = 30). Primary outcomes were: (i) impact of HA on haemodynamic stability and need for vasopressors (vasoactive-inotropic score) and (ii) sequential organ failure assessment (SOFA) score. Secondary parameters included the impact of HA on the course of hyperinflammation using interleukin-6 and procalcitonin, duration of mechanical ventilation, and lengths of intensive care unit and hospital stay.
Results:
Noradrenaline requirement was significantly reduced in the HA group postoperatively compared to the C group (HA: 0.03 µg/kg/min vs C: 0.08 µg/kg/min, P = 0.004 at 2 h, and HA: 0.02 µg/kg/min vs C: 0.04 µg/kg/min, P = 0.004 at 24 h). This translated into a significantly lower vasoactive-inotropic score in the HA group. SOFA score was less in the HA group at all time points and reached statistical significance 2 h postoperatively (HA: 5.77 vs C: 7.43, P < 0.001). Intraoperative HA significantly reduced interleukin-6 levels (P < 0.05) at all time points, and procalcitonin at 2 h after discontinuation from cardiopulmonary bypass (P = 0.005). The duration of ventilation, intensive care unit and hospital stays were shorter in the HA group compared to the C group.
Conclusions:
Intraoperative HA has the potential to mitigate hyperinflammatory response leading to improved haemodynamics after aortic root surgery, thereby shortening the duration of ventilation, and lengths of intensive care unit and hospital stay. However, it must be evaluated in larger cohorts.
