Noradrenaline, an adrenergic agonist with weak β-adrenergic activity, has been reported to have a more favourable haemodynamic profile than phenylephrine.
Phenylephrine increases cardiac output by raising cardiac preload …
WebIntroduction. Phenylephrine has been advocated as a first-line vasopressor agent for the treatment of maternal hypotension after spinal anesthesia for cesarean delivery; 1,2 however, the exact dose difference is poorly documented, especially in parturients with severe preeclampsia compared to parturients with normotension. 3 Previous studies have … WebInduction of general anesthesia frequently induces arterial hypotension, which is often treated with a vasopressor, such as phenylephrine. As a pure α-agonist, phenylephrine is conventionally considered to solely induce arterial vasoconstriction and thus increase cardiac afterload but not cardiac preload. mot fashion
