Högdos insulin–euglykemiterapi vid svår toxisk myokarddepression. Ett viktigt tillskott i behandlingsarsenalen
Sammanfattning
Fifty-nine patients who developed hemodynamic symptoms necessitating treatment with vasopressors or inotropes after poisoning with calcium channel blockers (CCB) and beta blockers (BB) between January 2010 and August 2016 were identified by a search of the Poisons Information Centre database. In-hospital circulatory arrest occurred in 16/59 (27 %) and the mortality rate was 7/59 (12 %). Two cases of analytically confirmed combined BB and CCB poisoning were treated with high dose insulin therapy (HIE) and are presented in detail. The outcome in both cases was good. They were the only cases in the study population treated with HIE, although signs of cardiac dysfunction was present in 55/59 (93%) and in all cases of circulatory arrest. Animal studies and international clinical cases indicate that HIE is a safe and effective method to improve cardiac function in CCB and BB poisoning, and its implementation in Sweden may improve the outcome for this at risk population.
