vasoactive

 [vas″o-ak´tiv]
exerting an effect upon the caliber of blood vessels.
vasoactive intestinal polypeptide (VIP) a peptide hormone that, in addition to its vasoactive properties, stimulates intestinal secretion of water and electrolytes, inhibits gastric secretion, promotes glycogenesis, causes hyperglycemia, and stimulates production of pancreatic juice.

vasoactive intestinal peptide (VIP), vasoactive intestinal polypeptide
a peptide hormone that, in addition to its vasoactive properties, stimulates intestinal secretion of water and electrolytes, inhibits gastric secretion, promotes glycogenesis, causes hyperglycemia and stimulates secretion of pancreatic juice.
vasoactive substances
substances which cause constriction of blood vessels; substances which actively dilate vessels, rather than relax an existing vasoconstriction, should be included. See vasoconstrictor agents and vasodilator agents.
vasoactive substances, endothelium-derived
includes nitrous oxide, prostacyclin and other prostanoids, unnamed relaxing or constricting factors released as a result of a tissue insult, e.g. hypoxia or excessive stretch.

Low intake of fluids, loss of fluids because of vomiting and pyrexial sweating, cytokine and NO mediated arterial vasodilatation specifically organ specific release of NO, resistance to vasoactive hormones, cytopathic hypoxia leading to decreased ATP synthesis, cytoadherence of PRBCs, etc all may contribute singly or in combination towards malarial ARF.

1,2) In contrast, another study performed on 75 patients with systemic hypoperfusion (defined as systolic blood pressure less than 90 mm Hg or requirement for vasoactive agents) found relatively good agreement between capillary whole blood and arterial whole blood glucose, with 95% limits of agreement of approximately [+ or -]30 mg/dL.
I started out, hesitant, skeptical and actually clueless, but I knew that if I could titrate vasoactive drips to maintain physiological homeostasis in critically ill patients, the computer couldn't possibly be that threatening
