  Purpose

The effects on brain perfusion of the two currently vasopressors used to treat accidental hypotension occurring during carotid surgery (i.e. ephedrine and phenylephrine) is not known, but a disadvantage to use phenylephrine is suspected, due to its mechanism of action and according to published reports
