#FOAMed Follow Up is back following the holiday hiatus. This past week was our quarterly tox rounds, and they focused primarily on cardiotoxicity.  A subset of EM FOAM has broken off into its own realm of FOAMTox, which has created numerous additional resources. Some popular sites to check out are The Poison Review and the toxicology library at Life in the Fast Lane.

• Dr. Hedge was tasked with covering the hypotensive and bradycardic patient, and he went over the presentation and treatment of the ABCDs mnemonic. The LIFTL EKG library crushes it per usual. Here’s beta/calcium channel blocker, digoxin effect, and digoxin toxicity. EMCrit has a breakdown of calcium channel blocker overdose treatment (with guest Leon Gussow of The Poison Review). LIFTL also has a short case of clonidine overdose. Recall that both clonidine and dexmetatomadine are both alpha-2 agonists.
• Dr. Nefcy ran through some cases, one of which was an OD on theophylline. Becoming more old school, but remains a drug that we need to know the side effects of. LIFTL has a short break down of it here.
• Dr. King covered Torsades de Pointe as well as some shakeweight gifs. Rob Orman of ERCast/EMRap interviewed ED ECMO’s Joe Bellezzo this past November regarding this very subject (sans shakeweight). There’s a great half hour podcast here. After listening, be sure to check out the write-up on the website of T de P by Dr. Weingart.
• Dr. Baltarowich discussed takotsubo. Sticking with a heavy LIFTL links this week, here’s an intro to takotsubo and a short case. Radiopaedia has some nice images as well.

That’s all for this week.
