EEG Monitoring During Cardiopulmonary Bypass Procedures
Severe neurologic complications following heart surgery are less prevalent due to improvements in surgical technique, perioperative care and extracorporeal circulation equipment [1, 2]. However, subtle neurological deficits still occur at rates up to 79% following cardiopulmonary bypass (CPB) [3, 4]. Multiple etiologic factors have been implicated and studied. Included are: equipment related microemboli, intraoperative hypotension, cannula placement and emboli from the surgical field [5, 6, 7]. Not examined are the effects of intraoperative treatment based on concurrent brain activity monitored intraoperatively by electroencephalography (EEG).
