Cerebral Oxygenation and Neurological Functioning After Cardiac Surgery

Cerebral Oxygenation and Neurological Functioning After Cardiac Surgery

The overall goal of this research program is to determine quantitative predictors of quantitative long-term neurological functioning following different cardiac surgery procedures. The investigators aim to generate a timeline of neurological function that includes pre-existing performance, post-operative delirium, and neurological outcome. Furthermore, the investigators will test the hypothesis that intraoperative regional cerebral oxygenation (rSO2) desaturations, as measured by near-infrared spectroscopy (NIRS) are associated with poor neurological functioning following cardiac surgery, as measured by a robotic device called the KINARM.

Inclusion Criteria:

• adult patients undergoing coronary artery bypass surgery +/- valvular surgery

Exclusion Criteria:

• pre-existing cognitive impairment or neurodegenerative condition
• any reason that participant cannot participate in follow up (lives too far away, limb amputation, speaks language other than english)
