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: Distracting injuries in c-spine injuries

Cervical spine assessment distracting injuries

“Distracting injury” is a frequent cited reason for imaging the cervical spine in blunt trauma patients, per the NEXUS study. In the Journal of Trauma in 2005 and 2011, studies aimed to narrow the definition of “distracting injury”. Although both are studies at different sites, both conclude the same:

  • Chest injuries may be considered “distracting injuries” because of their proximity to the cervical spine.

Example

So let’s say you are caring for a non-intoxicated motor vehicle crash patient with an isolated tibia fracture (i.e. a “long bone fracture”), no chest injuries, and no neck pain/tenderness. Per the NEXUS criteria, you might consider this patient to have a “distracting injury” because of the long bone fracture. Instead, the literature now supports your clinically clearing the cervical spine without imaging.

Wait, let’s rethink this. Does this mean that you should get cervical spine imaging for ALL blunt trauma patients with ANY chest wall tenderness?! NO. That’s just crazy. You should still factor in the mechanism of injury, severity of pain, and your clinical gestalt.

So for me, these “distracting injury” studies are helpful such that:

  • If your trauma patient does NOT have chest trauma, it may help you avoid unnecessary cervical spine imaging, as suggested by the NEXUS criteria.
  • If your trauma patient DOES have significant chest trauma, I have a lower threshold to obtain cervical spine imaging despite the neck being non-tender.

Paucis Verbis: Antibiotics for Cystitis and Pyelonephritis in Women

UrineBacteriaYou diagnose a 35 years old woman with uncomplicated cystitis. She is not diabetic and not pregnant. Which antibiotics should you give? What if she had pyelonephritis?

Answer: It depends on your local antibiogram.

San Francisco General Hospital 2010 Antibiogram

Today, go find out about your hospital’s local resistance rates for uropathogens to various antibiotics. For San Francisco General Hospital, I found our antibiogram publicly posted online. Urine isolates of E. coli demonstrate relatively high resistance rates to trimethoprim-sulfamethoxazole and ciprofloxacin:

  • Trimethoprim-sulfamethoxazole resistance rate = 33%
  • Cefazolin or Cephalexin resistance rate = 12%
  • Ciprofloxacin resistance rate = 16%

So based on the new 2010 practice guidelines by the ID Society of America and the European Society for Microbiology and Infectious Diseases,1 I should give:

  • Cystitis: Nitrofurantoin x 5 days, or cephalexin / beta-lactam x 3-7 days
  • Pyelonephritis: Ceftriaxone 1 gm IV x 1 + (ciprofloxacin x 7 days or trimethoprim-sulfamethoxazole x 14 days)

Paucis Verbis: Approach to rashes

Poison Oak rash

Contact dermatitis from poison oak

We see a variety of rashes in the Emergency Department. The first step is to accurately describe the rash. Is this a macule or nodule? Is this a vesicle or bulla? The next step is to quickly “profile” it to see if it fits any classic pattern by patient age, lesion distribution, or presence of hypotension. And finally, if you are still stumped, use an algorithm based on the rash type.

These figures are from March 2010’s Emergency Medicine Magazine. It’s not meant to be a comprehensive article on rashes but it sure does take the guesswork out of 90% of the rashes you see.

Paucis Verbis: An approach to persistent tachycardia

Sinus Tachycardia ECG
Tachycardia is a common clinical occurrence in the ED. Most of the time the etiology can be discerned through the history and physical exam, but sometimes it cannot. This is problematic especially when we are about to discharge a patient home but his/her heart rate is still 115 beat/min. We can’t send this patient home yet. Do we then have to admit them for work-up of persistent tachycardia?

Attached is a list of common causes of tachycardia in the ED, as well as potential diagnostic and therapeutic considerations. Rather than a shot-gun approach, a limited and thoughtful method works best.

Can you think of other potential causes?

Paucis Verbis: Spinal epidural abscess

Spinal epidural abscess anatomy illustrationOne of the most challenging diagnoses to make is that of a spinal epidural abscess (SEA), especially if you work in an Emergency Department which cares for many IV drug users and HIV patients. There’s never before been a published diagnostic guideline or algorithm which helps you with risk-stratification.

In the Journal of Neurosurgical Spine, a diagnostic guideline was prospectively evaluated on a small population (n=31) as compared to historical controls (n=55). They found that an ESR test had a sensitivity of 100% if a patient had at least 1 risk factor for SEA. A CRP test was much less helpful.

Not a practical algorithm

Unfortunately, they didn’t study the utilization rate of the MRI scanner with this guideline. Are they getting better results (fewer diagnostic delays and fewer cases of patients later in their clinical course) because they are just MRI-scanning more people? Almost everyone in my ED with back pain would fall into the Urgent/Emergent MRI box…  I’m not a fan of this algorithm.

Regardless, this algorithm may help you in shaping your diagnostic decision and medical decision making documentation.

Paucis Verbis: Fibrinolytics for Acute Pulmonary Embolism

Pulmonary embolism fibrinolytics

When would you give fibrinolytics for a Pulmonary Embolism?

This Paucis Verbis card summarizes recommendations found in Circulation’s recently published Scientific Statement from the American Heart Association. Although it is rare to give fibrinolytics for a pulmonary embolism (PE) in the Emergency Department, it is important to remember when lytics are indicated.

Paucis Verbis: Diagnostic testing tips for acute abdominal pain

acute abdominal pain

In the most recent EM Clinics of North America publication, Dr. Panebianco et al. discussed the evidence behind diagnostic tests for acute abdominal pain. There were some really great teaching points in this broad-reaching topic.

My favorite pearl: A 3-way acute abdominal series is too insensitive to rule-out any major acute causes of abdominal pain with confidence. So stop ordering them routinely. If you are worried about a perforated viscus, order an upright chest x-ray instead — more accurate and less radiation.
