High-dose insulin therapy based on a 1-10 U/kg/h dosing guideline and recommending avoidance of vasopressors appears to be effective in the treatment of toxin-induced cardiogenic shock. Hypoglycemia was the most frequent adverse event, followed by hypokalemia. Adverse events did not lead to adverse sequelae.
In this swine model, IN/G is superior to V/E to treat beta-blocker toxicity. IN/G has marked inotropic properties while the vasopressor effects of V/E depress CO and contribute to death. Increasing SVR in this condition is detrimental to survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
