New Development in Brain Monitoring for Cardiac Surgery

Published:November 18, 2022DOI:https://doi.org/10.1016/j.cjca.2022.11.006
      Use of brain function monitoring is gaining interest to improve patient safety during cardiac surgery and in the intensive care unit. In this review, we highlight the clinical relevance of brain monitoring such as the cerebral near-infrared spectroscopy (NIRS), processed electroencephalography (pEEG), and transcranial Doppler (TCD). A clinical case will be presented to illustrate the potential of combining those technologies to optimize patient management during cardiac surgery. Even if brain monitoring alters management, interpretation in brain function requires knowledge about hemodynamic parameters and should be combined with other monitoring technology.
