WebFeb 12, 1998 · We conclude that, unlike the effects of administering norepinephrine under baseline conditions, norepinephrine infusion during endotoxic shock actually increases renal blood flow and that this effect is not the result of an increase in perfusion pressure alone. WebAug 1, 2011 · Arterial hypotension is a common anesthetic complication. Perfusion of vital organs depends largely on arterial blood pressure. Mean arterial blood pressure (MAP) below 60 mmHg and systolic blood pressures below 80 mmHg can result in reduced perfusion of the vital organs. Oxygen debt can ensue in morbidity and mortality.
WebPhenylephrine is a pure vasoconstrictor and is not recommended for empiric use, although niche uses for phenylephrine include (1) difficulty raising mean arterial pressure in the presence of high cardiac output as well as (2) serious tachyarrhythmias induced by norepinephrine (not usually an issue).
