Paucis Verbis: Approach to rashes
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 [+]
Trick of the Trade: Crossed straight leg raise test
A 35 year old man presents with low back pain which radiates down his right leg to the level of the knee. Is this sciatica? Low back pain is one of the most common chief complaints that we see in the Emergency Department. In addition to the examination of the back and distal neurovascular function, we also need to test for evidence of a radiculopathy (compression or inflammation of a nerve root typically from a herniated disk). Because most disk herniations occur at the L4-L5 and L5-S1 level, you should test for irritation of the L4-S1 nerve roots. This is [+]
Paucis Verbis: An approach to persistent tachycardia
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. [+]
Trick of the Trade: Using a funnel for NG tubes
One of the indications for nasogastric (NG) tube placement is to instill fluids or medications. This may be saline or water for NG lavages or charcoal. You can manually push fluids into the NG tube via a 60 cc syringe, but this may take a long time for large volumes. [+]
Trick of the Trade: Splinting the ear
One of the hardest bandages to apply well is one for auricular hematomas. After drainage, how would you apply a bandage to prevent the re-accumulation of blood in the perichondrial space? Traditionally, one can wedge xeroform gauze or a moistened ribbon (used for I&D’s) in the antihelical fold. Behind the ear, insert several layers of gauze, which have been slit half way to allow for easier molding around the ear. Anterior to the ear, apply several layers of gauze to complete the “ear sandwich”. Finally, secure the sandwich in place with an ACE wrap, which ends up being quite challenging [+]
Paucis Verbis: Spinal epidural abscess
One 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 [+]
Trick of the Trade: Balloon animals in the ED
Back in July 2010, I wrote about using the Candleflame app to encourage pediatric patients to take deep breaths for a pulmonary exam. This app has also been useful in helping me roughly gauge the patient’s peak flow. [+]
Paucis Verbis: Fibrinolytics for Acute Pulmonary Embolism
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.

Trick of the Trade: Making a beanie hat
Scalp lacerations are a common condition in the Emergency Department. Some require no bandage over once the injury is repaired. Because the scalp is so vascular, others require a pressure dressing over the site to minimize hematoma formation. How do you bandage these patients? It is difficult to secure any wrap or square gauze over the site, because the head is round and the hair is slippery. [+]
Paucis Verbis: Diagnostic testing tips for 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. Adapted from [1] Go to ALiEM (PV) Cards for more resources.
