There are a variety of invasive or non-invasive methods for monitoring cerebral blood flow and cerebral metabolism in patients during operation with anesthesia, and different methods have their own scope of use. Transcranial Doppler can be used to monitor high-risk patients with intraoperative cerebral blood flow autoregulation dysfunction and patients with special positions during operation because of its convenience, continuity, and strong repeatability. Changes in cerebral blood flow detected by transcranial Doppler may be associated with postoperative central nervous system complications in patients. This article reviews the application of transcranial Doppler monitoring of cerebral blood flow in operation with anesthesia, aiming to provide a certain basis for the promotion of this technology in operation with anesthesia.
