Compared Efficacy and Tolerance of Two Vasopressors Used to Treat Preoperative Hypotension During Carotid Surgery (VP-hTA-XCar)

August 5, 2026 updated by: University Hospital, Clermont-Ferrand

Compared Efficacy and Tolerance of Two Vasopressors Used to Treat Preoperative Hypotension During Carotid Surgery. Prospective Randomised Controlled and Single Centre Trial

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
