title: [Cerebral blood flow monitoring].
abstract: Cerebral ischemic events remain a major problem in patients undergoing cardiac and thoracic aortic surgery. Efforts to improve outcomes have been made in many aspects which include cerebral monitoring. New technology is making it possible to shed a light to the brain, which historically used to be a black box during general anesthesia in the operating room. Cerebral brain monitoring methods include cerebral oxymetry using near infrared spectroscopy, trans cranial Doppler, Jugular venous oxygen saturation, bispectral index, temporal artery pressure monitoring. Cerebral oxymetry probably is the most commonly used method among these based on its simplicity and reproducibility. Though it is easy to obtain numbers from cerebral oxymetry, it is important to understand the principle and the limitations to interpret the results, properly.
