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.
My favorite supraglottic airway is the Cookgas Air-Q; it was created by an anesthesiologist, Dr. Daniel Cook (As always, I have no conflicts of interest). He just created a new device that allows the placement of an esophageal blocker through the laryngeal airway. I gave him a call to hear about the new product and in the course of that conversation, he gave me a ton of tips on the placement of laryngeal airways in general. Sorry about the audio quality, his cell phone was probably AT&T : ).
Electrocardiograms can be subtle; but you can’t miss them or patients die. Today, I got to interview Dr. Steven Smith. Dr. Smith is faculty at the Hennepin Program and author of one of the best books on EKGs in the ED, The ECG in Acute MI.
Dr. Smith’s EKG Blog is probably the best free EKG site out there for Emergency Physicians and Intensivists.
We cover a ton of stuff including the most subtle form of MI, why inferior depressions don’t mean inferior ischemia, and when a BOATload of calcium is a really good idea.
I was able to cajole Cliff Reid of the amazing blog, resus.me on to the EMCrit program. Cliff is truly a doc after my own heart as you will hear from the cast.
He is currently an EMS physician and Director of Training at the New South Wales Ambulance Service.
Cliff’s blog, resus.me is an incredible collection of timely articles on emergency medicine, ems, critical care and resuscitation.
Cliff and I discuss prehospital intubations, helicopters for EMS, and upstairs care, outside the walls of the hospital.

You have a 50 y/o male with bad bilateral pneumonia. BP 108/70, HR 96, RR 28. He is delirious, agitated, and looks sick, sick, sick! Saturation is 70% on a nasal cannula; when you try to place the patient on a non-rebreather (NRB) he just swats your hand away and rips off the mask. It is obvious to everyone in the room that this patient needs intubation, but the question is how are you going to do it?
Your first impulse may be to perform RSI, maybe with some bagging during the paralysis period. This is essentially a gamble. If you have first pass success, you (and your patient) may just luck out, allowing you to get the tube in and start ventilation before critical desaturation and the resultant hemodynamic instability. However, the odds are against you: bagging during RSI predisposes to aspiration, conventional BVM without a PEEP valve is unlikely to raise the saturation in this shunted patient, and if there is any difficulty in first-pass tube placement your patient will be in a very bad place.
Is There a Better Way???
In EMCrit Podcast 39, I try to decipher the management of hyponatremia in the ED. After reading countless articles from the nephrology literature…I can still attest that I have not a friggin’ clue about renal physiology. But I think I have found a simpler path to the work-up and treatment of low sodium in the ED.
