Acid Base: Part II

Part I was hard; Part II is even tougher. But I think there is light at the end of the tunnel. In this episode we go through the math of an acid-base scenario. You will begin to understand the quantitative approach, but you’ll also understand the standard approach. We will discuss why the “normal anion gap” is a myth.

Acid Base: Part I

I have spoken about it for a while, but I’ve finally gotten it done: the acid-base podcast. The podcast is going to be in 3 or 4 parts. They are segmented from a lecture I gave to my residents recently.

This lecture discusses a quantitative approach to acid base management. This is also known  as the Fencl-Stewart approach, the strong-ion approach or the physicochemical approach. It provides explanations for why acid base disorders occur in human pathophysiology. The classic method used in the USA is the Henderson-Hasselbalch (misspelled on my slides) approach. I find this method to provide no comprehensive explanation for why things are as they are. Through the quantitative approach, you can also understand the H&H approach and continue to use it with new insight.

When an ED starts providing advanced care for severe sepsis, lactate testing is an absolute requirement. Lactate use brings up a lot of questions, especially if it is not commonly ordered in your department. In this podcast, I discuss all of the lactate questions that have come up in the course of the NYC Sepsis Collaborative.

Severe CNS Infections

Severe CNS Infections are time dependent diagnoses! You must have a high index of suspicion, a good plan for your work-up, and rapid provision of treatment. After seeing a severely ill meningitis patient, I figured I would do a podcast on some tips and pearls on this topic.

Non-Invasive Management of Severe Sepsis

Young patient, lactate of 5.2, pneumonia… You know what you’re supposed to do–put in the central line and start early goal directed therapy. Problem is, most people can’t see sticking a central line in a patient that does not need pressors and otherwise looks well. Yet these patient have an annoying habit of going on to decompensate and perish. Well now there may be another way. Thanks to an article just published in JAMA, we may have a path to non-invasive treatment of severe sepsis. In this EMCrit Podcast, I interview Dr. Alan E. Jones, author of the article, Lactate clearance vs central venous oxygen saturation as goals of early sepsis therapy: a randomized clinical trial. Then I discuss how this article changes the game when it comes to caring for severe sepsis patients.
