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.
