Background: Extracorporeal circulation causes a systemic inflammatory response, that may cause postoperative haemodynamic instability and end-organ dysfunction. This study aimed to investigate the impact of minimal invasive extracorporeal circulation (MiECC) on the systemic inflammatory response compared with conventional extracorporeal circulation (CECC).
Methods: Patients undergoing coronary artery bypass grafting were randomized to MiECC (n = 30) and CECC (n = 30).
