[Vasopressin analogue injection as ultimate measure for counteracting severe catecholamine-refractory poisoning by several vasodilators taken with suicidal intent].
METHODS
A 78-year-old woman was admitted to the intensive care unit 9 hours after ingestion of 2 g of isosorbitmononitrate, 430 mg of amlodipine, 250 mg of benazepril and 600 mg of mirtazapin in suicidal intent.


METHODS
Clinical findings and invasive monitoring showed signs of a hyperdynamic hemodynamic cardiovascular failure caused by toxic vasodilatation.


METHODS
Despite of primary detoxication, intravenous volume infusion with calcium gluconate, glucagon and naloxone and administration (norepinephrine up to 2 micro g/kg/min) no hemodynamic stabilization was achieved. Only when the vasopressin-analogue argipressin was given peripheral vasodilatation was overcome and hemodynamic stabilization resulted. 10 hours after discontinuing argipressin and norepinephrine the patient developed a mesenteric ischemia, and she finally died on the third day after admission.


CONCLUSIONS
In circulatory shock due to toxic vasodilatation the use of vasopressin analogue argipressin can be helpful as an ultima therapeutic measure in catecholamine refractory shock caused by vasodilatation. Attention must be paid to overwhelming vasoconstrictor effects resulting in mesenteric ischemia.
