Ischemic Postconditioning in Cardiac Surgery (IPICS)

December 11, 2023 updated by: Mari-Liis Kaljusto, Oslo University Hospital
Ischemic postconditioning by repetitive cycles of reperfusion and ischemia has been proven both in animal models and in humans. This study aims to investigate the effect of ischemic postconditioning on postoperative hemodynamic function in a standard heart surgery patient population.

Detailed Description

Ischemic postconditioning is studied using cardiopulmonary bypass (CPB) and moderate hypothermia (32-34°C) in a patient population undergoing surgery of the aortic valve (repair/replacement ) or the ascending aorta. Postconditioning is applied by introducing reperfusion/ischemia via the cardioplegia line while the aorta is still cross-clamped thereby preventing the risk of additional neurological complications. All patients > 20 years eligible for aortic or aortic valve surgery and not affected by exclusion criteria, will be included.

The study is carried out as a randomised controlled multicenter study including 5-6 heart surgery centers.
