Neurologic Monitoring During Cardiac SurgeryUniversity Hospital Campus-LHSC, University of Western Ontario, London, Ontario, Canada; Department of Anesthesiology and Perioperative Medicine, University Hospital Campus-LHSC, 339 Windermere Rd., London, Ontario, Canada N6A 5A5 Strategies for basic and advanced neuromonitoring techniques are reviewed. Cerebral hyperthermia during rewarming and unrecognized jugular venous obstruction are associated with cerebral compromise and can be readily detected and avoided. The strengths and limitations of transcranial Doppler and electroencephalographic monitoring are reviewed, as is use of noninvasive cerebral optical spectroscopy and jugular venous oximetry. The potential for reduction in perioperative stroke by using epiaortic scanning to detect and avoid otherwise nonpalpable atherosclerotic plaque, is also reviewed.
