An intuitive way to use ultrasound to evaluate sick patients along the peri-shock to full shock spectrum, based on clinical presentation. I call it, “Think High or Think Low.” I made these cards for the new UCLA EM interns to wear with their ID badges. @UCLAEMRes #POCUS

@CorydonWW By “it” I mean IVC.

@CorydonWW Think EKG vs cath lab for potential ischemic chest pain. In terms of volume assessment, assessing the etiology of AKI, and/or the question to give fluids or diurese, it is somewhere in the middle, with high accuracy in most scenarios and high repeatability.

@atchiem can we discuss this thread next shift?

@CorydonWW Lastly, as Dr. Prager mentioned, volume assessment is not the same as assessing fluid responsiveness in septic shock patients. I made this video ten years ago that addresses the spectrum of POCUS tools to help manage these patients, which hasn’t changed: youtu.be/xn3r66mFrYY?si…

@CorydonWW Of course! Dr. Prager’s points are 100% true. With anything in medicine, there are tests that are highly accurate but costly, time intensive, and/or very technical to perform. On the other end of the spectrum, there are tests that are mostly accurate, fast, and easily repeatable.

@CorydonWW As an educator, I am also always considering my audience. For advanced POCUS, yes, there is more to IVC. For most physicians, though, IVC (and US assessment of JVP) are much more valuable and practical.

Such an excellent review of ECG findings in occlusion MI in @AnnalsofEM A lot of value in reading and collaborating with our colleagues in other departments. Recommend reading! sciencedirect.com/science/articl…

🧵regarding the introducer sheath commonly known as a 'Cordis' catheter. We'll go over what it was originally designed for and why it ended up being adopted by other specialties for entirely different reasons. Also we'll look at its accessories and see what's inside one. (1/ )

This is a high-yield, quick read about CT in acute stroke. @UCLAEMRes

We just published this in The Journal of the American College of Cardiology -- Advances (JACC Advances) "State of the Art Review".   It is a REALLY interesting read, using quotes from Thomas Kuhn's book "The Structure of Scientific Revolutions" (the book that coined the word "paradigm" and "paradigm shift").  Here is the first quote: “Scientific revolutions are inaugurated by a growing sense, again often restricted to a narrow subdivision of the scientific community, that an existing paradigm has ceased to function adequately in the exploration of an aspect of nature to which that paradigm itself had previously led the way.” —Thomas Kuhn Full text pdf: pdf.sciencedirectassets.com/781222/1-s2.0-…

@chungk1031 We’ve been using phenobarbital for patients presenting with alcohol withdrawal in the ED for quite some time. Many respond with 1-2 doses with improvement to avoid admission. pubmed.ncbi.nlm.nih.gov/20825805/ However, there’s not much evidence to show superiority of either meds.

Phenobarbital is my new favorite drug for alcohol withdrawal. Where has it been all this time!?! #MedTwitter

This was fun! 😄

What a fun day 2 at #ACEP24! @atchiem & I are so excited for our @WINFOCUS pro con debate we decided to bring our costumes and shoot a few extras here 😅. Thanks to our volunteer videographer & extra/actor. @ACEPNow @ACEP_EUS

First-year medical students learned about POCUS (#PointOfCareUltrasound) from a team of @UCLAHealth physicians & senior med students. POCUS allows for safer procedures and more accurate & timely diagnoses: uclahs.fyi/dgsompocus

#TheyNotLikeUs 😎 Our new interns are here and we are so excited!

Congratulations to our graduating Class of 2024 ~ we are so proud of everything they have accomplished over the last 4 years and wish them the best of luck wherever they are going (or staying 🥰)! They are superstars and we know they are #ReadyForAnything #BestJobsinEM @CORD_EM
