Abstract
Intraoperative hypotension is normally avoided by anesthesiologists. However, for the Personalized External Aortic Root Support (PEARS) procedure, deep-induced hypotension is an essential requirement for the surgeon to be able to manipulate the aortic root. In this procedure, blood pressure and middle cerebral artery blood flow velocity were monitored. In this study, we assessed cerebral autoregulation during sustained hypotension, to give an insight into its behavior during hypotension.
