WebPhenylephrine (PE) and norepinephrine (NE) may be used to maintain adequate blood pressure and tissue perfusion in patients with septic shock, but the effect of NE combined with PE (NE-PE) on mortality remains unclear. We hypothesized that NE-PE would not inferior to NE alone for all-cause hospital mortality in patients with septic shock. WebOct 10, 2011 · The effects of NE-induced variations in mean arterial blood pressure (MAP) on renal blood flow (RBF), oxygen delivery (RDO (2)), glomerular filtration rate (GFR) and the renal oxygen supply/demand relationship (renal oxygenation) in vasodilatory shock with AKI have not been previously studied.
Phenylephrine - an overview ScienceDirect Topics
Phenylephrine is widely believed to reduce renal blood flow and thereby impair renal function. However, phenylephrine doesn't vasoconstrict the renal vasculature more than other vascular beds. Thus, it is possible that the effect of phenylephrine on renal blood flow, similar to the effect on cardiac output, may be context … See more Make no mistake, I'm not very fond of phenylephrine.
