Detailed Description
The research subjects are to be treated with CPB with according to local standards (perfusion index 2.4 x body surface area). While measuring impact on cerebral autoregulation with the aid of Near InfraRed Spectroscopy (NIRS) and brain injury markers in blood, research subjects depending on initial hemoglobin value, will divide into two subgroups: one with DO2I of >280 ml/min/m2, and one with DO2I of <280 ml/min/m2.
DO2I will during CPB be calculated using the patient data monitoring system Metavision.
With a correlation analysis between NIRS and MAP (mean arterial pressure) a COx (Cerebral Oxymetry Index) r-value can indicate impact on cerebral autoregulation with values >0.3 - 0.5 during use of CPB 4.
Brain injury markers (Tau, Glial Fibrillary Acidic Protein (GFAP), Neurospecific Enolase (NSE)) are collected during 5 occasions during the first 24 hours and then once per day for 4 days, as well as markers for AKI (S-Creatinine) in some extent.
Registrations during the intensive care regarding delirium, stroke or other neurological impact will also be included in the study.
