US, Canadian and European critical care and toxicology societies recently published a consensus recommendation is the management of CCB poisoning.
1. First line therapy remains unchanged: IV calcium, atropin, high-dose insulin (HIE) therapy, vasopressor support (norepinephrine and/or epinephrine).
2. Refractory to first line therapy: increase HIE, lipid-emulsion, transvenous pacemaker
3. Refractory shock, periarrest or cardiac arrest: Above (#1 & #2) plus ECMO if available.
Overall, there has not been a signficant changes to the current management of CCB poisoning. However, there is a nice flow chart of the algorithm/recommendation in the article. The authors note that the "level of evidenc was very low" for all intervention.
A. asymptomatic patients
B. First line therapy
