Back in 2015, Dr. Sergey Motov’s (@painfreeED) group published a study demonstrating the efficacy of low-dose ketamine compared to morphine for analgesia in the ED. Here’s my quick analysis of that study as a UMEM pearl. The question, though, is how best to administer the 0.3 mg/kg IV ketamine dose while minimizing the risk of adverse effects.
Fortunately, Dr. Motov’s group has just published a follow-up study addressing that exact question.

Ketamine is steadily gaining traction as a treatment option for excited delirium and/or severe agitation in both the prehospital and ED settings. We published a summary of the available data back in 2015 on Academic Life in EM. Last year in 2016, two prospective studies added important information to our understanding of the role of ketamine; one in the prehospital setting by Dr. Jon Cole’s group out of Minnesota and one in the ED from Dr. Geoffrey Isbister’s group in Australia. I was invited to write a commentary along with the Cole study, also published in 2016.
Hot off the press in 2017 is another prospective study, this time from Dr. Jeff Riddell’s group in California (@Jeff__Riddell).

Toxin-induced cardiogenic shock is a life-threatening condition characterized by severe hypotension and ineffective tissue perfusion. Many drugs can lead to cardiogenic shock in overdose, for example beta blockers or calcium channel blockers. Given the poor prognosis of these cases AND theoretically-sound reasoning, vasoactive agents make sense as a therapeutic option. A detailed, comprehensive review, just published online in Clinical Toxicology, asks the question “Are vasopressors useful in toxin-induced cardiogenic shock?”

The FDA-approved dosing for IV acetylcysteine (NAC) for acetaminophen overdose is complicated: a 1-hour loading dose, followed by a 4-hour maintenance infusion at a different rate, followed by a second maintenance infusion for 16 hours at yet a different rate. Back during my clinical toxicology fellowship, we published a study that found there was an interruption in antidotal therapy > 1 hour in 18.6% of cases (and medication errors in 33% of cases overall).

I had the opportunity to attend the North American Congress of Clinical Toxicology (NACCT), the annual meeting of the American Academy of Clinical Toxicology (AACT) held in Boston, Massachusetts September 12-16, 2016. Besides attending some awesome educational sessions related to clinical toxicology, I also had the chance to meet and connect with friends and acquaintances, old and new, from within the #FOAMtox community, which always proves to be a great experience.
I served as “ghost” tweeter behind the @ALiEMconf Twitter account, and shared clinical pearls from the meeting that are worth knowing and/or further exploration for the #FOAMed community. Among those that I shared from the account as well as my own personal Twitter account, listed below are my top 10 favorite pearls that I gained from the conference:
