PV Card: Normal Values for Ultrasound Measurements

As emergency medicine providers become more proficient in using bedside ultrasonography as a diagnostic tool, it can be difficult to remember all of the normal cutoff values. Is it 3 or 5 mm as the cutoff? Thanks to the team at UCSF (Dr. Maria Beylin, Dr. Scott Fischette, and Dr. Nate Teismann) for creating a succinct PV card listing the key numbers to remember. You can download this PV card into your mobile device as a reference guide, or you can even print and attach to each of your ultrasound machines!

NEXUS Chest CT Decision Instruments in Blunt Trauma

One of the five 2014 American College of Surgeons’ Choosing Wisely recommendations is to avoid routing whole-body CT imaging of trauma patents, also known as the ‘pan-CT’. Until now, no validated decision instrument existed to help guide clinicians decide whether to obtain a chest CT in the setting of blunt trauma. This month, Dr. Robert Rodriguez and the multi-institutional NEXUS Chest CT research team published a paper describing the derivation and validation of 2 decision instruments in PLOS Medicine [1].

AIR Series: Cardiology – CHF, PVD, and Others (part 2)

As mentioned last module, the FOAMsphere contains a phenomenal amount of cardiology content. Accordingly, the CORD testing schedule and our cardiology module has been divided into two parts. Below we have listed our selection of the 12 highest quality blog posts within the past 12 months (as of August 2015) related to acute coronary syndromes, curated and approved for residency training by the AIR Series Board. In this module we have 6 AIRs and 6 Honorable Mentions. We strive for comprehensiveness by selecting from a broad spectrum of blogs from the top 50 listing per the Social Media Index.

ALiEM Bookclub | Dreamland: The True Tale of America’s Opiate Epidemic

They started at once, and went about among the Lotus-eaters, who did them no hurt, but gave them to eat of the lotus, which was so delicious that those who ate of it left off caring about home, and did not even want to go back and say what had happened to them, but were for staying and munching lotus with the Lotus-eaters without thinking further of their return.

Your Patient In Extremis: THAM To The Rescue?

One of the final common denominators dictating the success or failure of any resuscitative effort, be it a trauma or medical code, is the patient’s acid-base status. In the presence of acidosis, many of the tools at your disposal, including vasopressors, become impotent and the patient’s ability to strike a balance between bleeding and clotting or mounting an appropriate inflammatory response become deranged.^1–6 So what are the options to tilt the acid-base status in our favor?

ALiEMU CAPSULES Module 3: Pharmacology of Emergency Airway Management – Part 1

We are thrilled to announce the next installment of ALiEM CAPSULES: P harmacology of Emergency Airway Management (part 1), which was just published to the ALiEMU site. This is the first part of a 2-part course focusing on the pharmacology of the emergency airway. For this CAPSULES module we are introducing a multimedia-enhanced learning experience. You will find HD videos throughout the module providing further educational content. Some of the quizzes are also accompanied by video cases followed by a question based on the case you just watched. If you cannot use audio on your device, no problem, all videos are closed captioned (just hit the CC button in the YouTube window). We hope these videos further enrich your ALiEMU CAPSULES educational experience and we welcome any suggestions or comments!
