ALiEM Cards is point-of-care reference library of narrowly focused, easily digestible cards for the practicing emergency physician or learner (formerly known as PV Cards). As of July 2017 led by the team of Dr. Jeremy Voros and Derek Sifford, we have rebranded these into “ALiEM Cards”.

Paucis Verbis card: Ottawa knee, ankle, and foot rules

Often times, I get called to triage to help decide whether a patient should be sent to Radiology for an initial x-ray after injuring their knee, ankle, and/or foot. After teaching one of the nurses about the Ottawa rules, she taped a list of these rules on the triage wall.

Paucis Verbis card: Vasopressors and Inotropes for Shock

The treatment of shock should focus on correcting the underlying pathophysiology. With persistent hemodynamic instability, a vasopressor and/or inotrope should be selected. Reviewing receptor physiology can help you select the best-fit agent for the patient’s clinical condition. There is an especially useful table on medication selection in the reviewed 2008 EM Clinics of North America article.

This installment of the Paucis Verbis (In a Few Words) e-card series reviews Vasopressors and Inotropes for the Treatment of Shock.

Paucis Verbis card: Skipping the CT prior to LP for meningitis

With increasing awareness of CT’s irradiation risk, I thought I would review a classic 2001 article from the New England Journal of Medicine. Head CT’s previously were commonly performed prior to all lumbar punctures (LP) to rule-out meningitis. When can you safely go straight to an LP without imaging?

Caveat: This review only applies to those patients in whom you suspect meningitis. This does not apply to those being worked up for subarachnoid hemorrhage.

Paucis Verbis card: Early goal directed therapy

One of the landmark studies in sepsis was conducted by Dr. Emanuel Rivers (Henry Ford) and published in the New England Journal of Medicine in 2001. By managing patients with severe sepsis and septic shock with an “early goal directed therapy” approach, there was an absolute risk reduction of 16%. Furthermore, the number needed to treat to save a life was 6 patients!

This installment of the Paucis Verbis (In a Few Words) e-card series reviews Early Goal Directed Therapy algorithm. The layout is borrowed from a Cleveland Clinic Foundation (CCF) flowchart.

Paucis Verbis card: ABG interpretation

I have yet to find a better arterial blood gas interpretation review article than the 1991 Western Journal of Medicine summary by Dr. Rick Haber.

This installment of the Paucis Verbis (In a Few Words) e-card series reviews ABG Interpretation. The recent addition of an ABG machine in our ED has made a tremendous difference in our ability to care for undifferentiated patients. This is a refresher in making heads and tails of mixed acid-base disorders.

Paucis Verbis card: Angioedema

Recently, a patient presented with angioedema after starting taking an ACE-inhibitor. There was upper lip swelling, similar appearing to the case above. He also experience a hoarse voice. Before the advent of fiberoptic nasopharyngoscopy, it was assumed that there may be laryngeal edema. Fortunately, using technology, we were able to visualize a normal epiglottis and a grossly normal laryngeal anatomy.

Should patient with angioedema be admitted?

The 1999 study on admission guidelines, of course, should be weighed with physician judgment and the patient’s social issues. The study was retrospective and the results should be weighed carefully. For me, generally I admit all cases involving intraoral structures and progressively worsening extraoral angioedema. I also perform fiberoptic nasopharyngoscopy on all patients with voice changes.

Paucis Verbis card: Knee exam

How accurate is the clinical knee exam?

JAMA published a meta-analysis trying to answer this question. Although they include patients with acute and chronic knee pain, it’s a good general review of the knee anatomy, historical clues, and exam elements.

In the ED, the knee exam is challenging because we see very acute injuries where knee pain and swelling often preclude an accurate exam. For patients with an equivocal exam, be sure to refer for orthopedic follow-up. A repeat exam should be performed once the pain and swelling subside.

This installment of the Paucis Verbis (In a Few Words) e-card series reviews the Knee Exam.

I used to be all confused and had a hard time memorizing all the different maneuvers (especially for the meniscus). It is much easier to remember after doing these knee exams routinely. Particularly, the lateral pivot test and McMurray test can be done with several rounds of simultaneous knee flexion-extension, internal-external rotation, and valgus stressing. Looking at diagrams almost makes things more confusing.
