Vasopressor Use in the Critical Care Unit for Treatment of Persistent Post-carotid Artery Stent Induced Hypotension

Introduction Hypotension is common following carotid artery stenting (CAS), and may be mediated by vagal stimulation and/or suppression of spinal sympathetic outflow. Both mixed α/β agonists (dopamine (DA)), and more selective α- agonists (norepinephrine (NE) and phenylephrine (PE)), have been used, but the most effective treatment of post-CAS hypotension is unknown.
