WebMar 14, 2016 · Phenylephrine can affect cardiac output in several ways: Reflex bradycardia: Increased blood pressure may trigger the carotid baroreflex, causing a decreased heart rate which reduces cardiac output. Venoconstriction: Constriction of veins increases venous return (i.e. the preload), potentially increasing cardiac output.

WebJul 11, 2024 · Phenylephrine is a direct-acting sympathomimetic amine that functions as an alpha-1 adrenergic agonist. Its chemical structure is related to epinephrine and ephedrine and possesses potent vasoconstriction properties when given intravenously or applied directly to mucosal membranes. WebPhenylephrine is a commonly used vasopressor in the neurologic intensive care unit (neuro ICU), and due to its modest potency, the risk of local tissue injury from extravasation may be overestimated. The purpose of this study was to evaluate the safety of phenylephrine infusion through peripheral intravenous catheter (PIV) in the neuro ICU.
