Paucis Verbis Cards “In Few Words”

Just in case people are not familiar with the free PV review cards as posted by ALiEM (more than 150), I have linked to a particularly good one dealing with algorithms for rash management: paucis-verbis.  These were also highlighted as very useful in the ACEP Now, Nov 2016; and back in 2013 they were brought up by Buckingham on Room9ER.  I have attached photos of the rash algorithms below, might be a potentially very applicable Norton Children’s reference.

Studying Core Texts

I’ve recently had several of the interns asking me about studying. I think all of us should be studying one of the core texts: Rosen’s, Tintinalli’s, or Harwood-Nuss. My own preference is for Tintinalli’s for a number of reasons. It is the most direct, in terms of what do I need to know to take care of a patient with this condition. It is also slightly more comprehensive than Rosen’s. I also love that it has three versions: Emergency Medicine: A Comprehensive Study Guide; Emergency Medicine Manual (with a new version coming out soon); and Emergency Medicine: Just the Facts. For those that don’t know, the manual is a shortened version of the big book, still in paragraph form.  Just the Facts is an outline version. I use the big book as my primary resource, the manual when I just can’t make myself read the renal chapter, and Just the Facts as a quick review.

Rosen’s is a wonderful book, extremely well written, and something I plan to read after residency. Hawood-Nuss is too simplistic, leaves out too much of what a good ER doctor needs to know, and in my opinion is only suitable for NPs and PAs.

If you are trying to decide which book works for you, pick a couple of chapters of each book, read the chapters and see what works better. Notice that I say a couple chapters, because each chapter is written by different authors. You don’t won’t to stick with less than ideal book, just because one chapter was written beautifully.

A resource I recently discovered and have been enjoying is CrackCast. It is written by a Canadian group and they publish a new lecture each week going over a single chapter of Rosen’s, in order. Now even though I am a Tintinalli’s man and the material is slightly different, core content is core content. The lectures are wonderful.

CRACKCast

Something else wonderful about this group is their belief in spaced repetition. The group publishes flashcards for every lecture that they do.

For our interns, here are a couple previous blog posts about learning and spaced repetition:

FOAMed

Nice little post from Lauren Westafer, who just finished medical school and is fairly well known amongst FOAMers (FOAMeders?). Reminds us to be tentative about accepting everything we read on the internet.

She apparently gave a SMACC talk which is a pretty big deal. I was linked to her post on the Life in the Fast Lane weekly review, which I consider pretty much the best roundup of FOAMed on the web.

Public health for adrenaline junkies

Public health is associated with the least interesting courses of medical school (epidemiology and biostatistics). It has been linked to ED frequent flyers and psych hold patients (social and behavioral health). One might say it’s an integral part of vague clinical decision rules and flip-flopping society guidelines and Press-Ganey scores.

It’s also something us ED docs do every day, whether we want to or not. There’s no reason why we shouldn’t try to understand it and do it better.

Kiran and I have been developing a website dedicated to public health for ED personnel. It’s a FOAMed site. Our plan is to get it tied in with sites like EMCrit, ALiEM, LITFL, and the like. It’s still a very young project, but there’s a couple articles posted for you to glance at.

If anyone is interested in population health, there’s a ton of uncharted territory and we’d welcome the collaboration. Just let us know how you want to be involved. Also, tell your friends.

 

The Hypercoagulable Liver Failure Patient?

Hey Guys,
Just listened to a portion of April EM:RAP (so if you’ve heard it already here’s a little repetition) and was surprised to hear their Notes from the Community Section about coagulopathy in Liver Disease, which basically informed me that many liver patients are at just a high of risk of thrombosis as they are of bleeding.

3 Articles were referenced:
– Tripodi A, Mannucci PM. The coagulopathy of chronic
liver disease. N Engl J Med. 2011 Jul 14;365(2):147-56.
– Villanueva C et al. Transfusion strategies for acute upper gastrointestinal bleeding. N Engl J Med. 2013 Jan 3;368(1):11-21.
– DeLoughery TG et al. Invasive line placement in critically ill patients: do hemostatic defects matter? Transfusion. 1996 Sep;36(9):827-31.

Summary:
– The liver makes both procoagulant and anti-coagulant proteins which can be actually reduced close to equally rendering the patient basically in equilibrium (thus not so hypercoagulable).
– No study has shown that coagulation defects predict issues with procedures (but the experience of the clinician performing the procedure does).
– INR is not standardized in Liver Failure patients (like it is with Warfarin) and thus is not that helpful.
– PT & PTT may also not be helpful in patients with liver failure (due to the variability of loss of clotting factors)
**Fibrinogen may be low in liver failure patients, and you may consider replacement of this with Cryoprecipitate (10 units of Cryo increases the Fibrinogen by 100mg/dl).
– Raising intravascular volume with pRBCs may make them bleed more.

For the full references & discussion see the EM:RAP written summary. Perhaps this is something we should discuss with our GI colleagues and/or MICU people. Any thoughts?

March EM:RAP Summary

EMRAP_2014_03_March_3.1.14[1]

Hey Guys,
Just some things I learned on EM:RAP this month, and since I’m on admin thought I would post a few things.

The DRE (not the rapper Dr. Dre): from the Fingers & Foley’s section on EM:RAP; reviewed Esposito TJ et al. Reasons to omit digital rectal exam in trauma patients: no fingers, no rectum, no useful additional information. J Trauma. 2005. They had 512 trauma patients at a Level I Trauma Center. “the negative predictive value of both the rectal exam and other clinical indicators was very high: 99%. However if the other clinical indicators missed the injury, so did the rectal exam. It didn’t add any information”
Basically showed added value of a rectal exam to be very minimal, and that ROUTINE RECTAL EXAM IS NOT RECOMMENDED. BTW, this is in the journal of trauma which is well-regarded amongst our surgery friends.

How to identify if patient’s contact lens is still in the eye (e.g. if patient has eye pain and feels like its still in there and can’t find it): Use Fluorescein much like you would for corneal abrasion as it will stain the contact lens as well, allowing you to find it (then you can evaluate for corneal abrasion at the same time). *keep in mind contact lens will be ruined*

Subarachnoid Hemorrhage: from an article in JAMA in Sept 2013 with 10 university affiliated Canadian EDs. Tried to come up with a decision rule for SAH and basically came up with:
The decision rule including any of age 40 years or older, neck pain or stiffness, witnessed loss of consciousness, or onset during exertion had 98.5% (95% CI, 94.6%-99.6%) sensitivity and 27.5% (95% CI, 25.6%-29.5%) specificity for SAH. Adding “thunderclap headache” (ie, instantly peaking pain) and “limited neck flexion on examination” resulted in the Ottawa SAH Rule, with 100% (95% CI, 97.2%-100.0%) sensitivity and 15.3% (95% CI, 13.8%-16.9%) specificity.
**Key points: this decision rule is more to identify high risk patients and the high risk symptoms. Sensitivity was very high, but specificity very low. Also keep in mind there are other important causes of headache to keep in mind**

Biphasic Reactions in Anaphylaxis: from Annals of Emergency Medicine in November 2013. A chart review was performed over 5 years and had ~500 pts with anaphylaxis, but also documented allergic reactions. Found biphasic reaction was extremely rare (2 cases while in the ED, and 3 out of the ED), with a rate of 0.4% while in the ED. 6% bouncebacks in the anaphylaxis group, none of which died and none of which came back in anaphylaxis. This study was limited in that it was retrospective, and there was variability in the outpatient management of these patients (unclear who was DC’d with what if any medications)
Rosen’s states corticosteroids can be helpful in reducing risks of protracted anaphylactic reaction and biphasic anaphylaxis (7-10 day course). H1 & H2 antihistamines are helpful in reducing some of the symptoms of anaphylaxis. 5-Minute Emerg Consult recommends Epi-Pen for those with anaphylaxis.
No Formal observation time has been established, though Rosen’s says 2-6 hours; with longer observation times/admission for those with prolonged reaction or requiring multiple dose epinephrine

Sorry this is so long, but I’m on Admin so thought I’d post something. Attached you’ll find the March Written Summary with all the articles they referenced. Hope this is helpful.
