Definitely very different levels of engagement.

There's still such an important place for medical education in social media.
As education lead it's a source of so many great and thought provoking papers and concepts out residents benefit from

The BICAR-ICU-2 trial just dropped!

RCT involving IV bicarb in metabolic acidosis among patients with mod-severe AKI

Bicarb didn't affect mortality but it reduced the need for dialysis & risk of bacteremia

VERY similar conclusions to BICAR-ICU-1

"One intangible advantage of capillary refill time is that performing it brings the clinician back to the bedside to reassess the patient. This act may be itself the holy grail of early sepsis management."

great piece on #sepsis

I would normally not have batted an eye at this paper

But it’s by Robert Hahn, and is a nice overview of everything we know about fluid redistribution in the critically unwell- including gel phase, some glycocalyx stuff, 3 compartment models, and albumin escape rates

normal mentation *doesn't* indicate adequate systemic perfusion

especially in cardiogenic shock, people can mentate well despite terrible CO & systemic perfusion

poor mentation is sometimes an early sign of *septic* shock, but often a very late indicator of other shock states #EMIMCC

I.e. "I wondered if it could be a PE but the Wells Score is low so I don't think it is a PE"
Or
"Someone sent a DDimer which is positive but I checked the Wells Score and it's low risk so I don't think it's a PE"

It sounds basic, and I see you allude to this point in the table, but the main pitfall I see is people using Wells to decide whether they should be considering PE, instead of using it because they've already used their acumen to suspect it and want to determine how to now investigate.

minor updates to the antiemetic chapter

🀒 inhaled isopropyl alcohol pads are safe, fast, and underutilized

🀒 ondansetron is often a front-line drug due to favorable safety profile

🀒 olanzapine is a highly effective, broad-spectrum agent that is underutilized

I’m obviously a bit biased, but I believe there is greater danger in misclassification of non-septic shock (especially cardiogenic) as septic shock than from delayed recognition of septic shock. #emimcc #cccsky

Sub30: Feasibility study of a pre-hospital extracorporeal membrane oxygenation (ECMO) in patients with refractory out-of-hospital cardiac arrest in London, United Kingdom Out-of-hospital cardiac arrest (OHCA) carries a significantly poor prognosis with fewer than one in ten patients (∼9%) surviving to hospital discharge with some evidence suggesting that survival rates may even be decreasing to 7.8β€―%1–2 Survival is inversely correlated to the time taken to restore a spontaneous circulation, and cardiac arrests refractory to initial resuscitation attempts lead to very low neurologically intact survival rates.3 Extracorporeal cardiopulmonary resuscitation (ECPR) describes the implementation of extra-corporeal membrane oxygenation (ECMO) during ongoing resuscitation and is emerging as a treatment to improve outcomes for patients in refractory cardiac arrest.

Beautifully articulated as always

It's not just about rate of patients seen. *Emergency* Medicine needs time and space to train, reflect, innovate, discuss and enjoy the unique challenges it faces. These aspects are still work and service. They've been devalued but they're more important than ever

Defibrillation and refractory ventricular fibrillation Of patients with out-of-hospital cardiac arrest (OHCA) presenting in ventricular fibrillation (VF), the majority require multiple shocks.1 Guidelines recom

Interesting article. A lot of what we label as refractory VF isn’t refractory at all. It’s actually recurrent.

Is there a way in which we could change defibrillation strategies or antiarrhythmic drug administration to better address this?

Skytorial: Five pearls on olanzapine 😁

Between agitation and nausea/vomiting, olanzapine has a wide range of use.

Olanzapine is generally not a front-line agent (e.g., haloperidol or ondansetron often are). But sometimes, it really comes in clutch....
