Study Summary
The purpose of this study is to assess cerebral blood flow velocity (CBFV) following regional anesthesia for shoulder surgery. The results of this study will help to further understand the physiologic effect of the interscalene nerve block on cerebral blood flow.
Primary Outcome
The TCD automatically measures blood flow velocity in the main cerebral arteries of the circle of Willis. We will target the MCA which is the closest to the temporal bone therefore the most easily accessible for insonation and monitoring. We will do a bilateral monitoring.
