One of the anaesthetist's main objectives is to maintain proper organ function by ensuring that organs are well perfused and oxygenated. Hypoperfusion during general anaesthesia (perfusion that is too low) increases the risk of post-operative organ dysfunction, and can therefore have serious consequences for the patient's health. Among the noble organs, the brain is the most sensitive to intraoperative hypotension, due to its high metabolic activity. However, no specific biomarker of cerebral hypoperfusion is currently available for routine use. The aim of this fellowship is to study how to easily detect cerebral hypoperfusion during general anesthesia using routinely available EEG biomarkers. These biomarkers will help determine the optimal personalized blood pressure level to be maintained under general anesthesia, and ultimately reduce postoperative complications.
