Intraosseous vs. Intravenous Access during Out-of-hospital Cardiac Arrest: A Bayesian Secondary Analysis of a Randomised Clinical Trial

05/20/25 • 11 min

In out-of-hospital cardiac arrest, time is life, and the race to restore circulation is on. But what's faster or better: intravenous (IV) or intraosseous (IO) access? A new study puts this long-standing debate to the test—and the results may surprise you.

In this episode, we break down the findings from nearly 1,500 cardiac arrest cases. Spoiler: the data suggests it's not how you get access that matters—it's that you start resuscitation fast. Tune in to find out why this could streamline emergency protocols and change how we approach prehospital care.

The Cognitive Pause

You’ve given fluids, started pressors, and checked all the boxes... but your patient isn’t improving. Now what?
In this episode of Talking Shift, Dr. Haney Mallemat sits down with Dr. Anand "Swami" Swaminathan to break down one of the most powerful tools in emergency medicine and critical care: The Cognitive Pause. When the usual approach fails, it's time to stop, reassess, and challenge your assumptions before spiraling deeper into the resuscitation rabbit hole.
They unpack:

When to switch from reflexive to reflective thinking
Clues you’re treating the wrong diagnosis
How to avoid cognitive traps in septic shock
Swami’s go-to checklist during a pause (think: acidosis, adrenal, hypothyroid, occult bleeding, anaphylaxis, calcium, and more)
Real-life cases that highlight the importance of a well-timed pause
Why Hickam's Dictum > Occam’s Razor in the ED

Whether you're new to the resus scene or deep in the ICU trenches, this episode will sharpen your thinking and change how you approach critically ill patients.

Listen now and give your clinical brain the reboot it needs.
