Paucis Verbis card: Croup

The most common cause of stridor in pediatric patients is croup, or laryngotracheobronchitis. The distinct high-pitched, seal-like,”barky” cough can be heard from outside the patient’s room often.

Check out the YouTube clip above. Go to the 1:15 mark (near the end) to hear the barking cough. Poor but cute kid.

What is the current treatment regimen? Did you know that the traditional treatment with cool mist or humidified air have shown to be of no added benefit?

Trick of the Trade: Modified HAT trick revisited

I finally tried the Modified HAT (Hair Apposition Technique) trick for the closure of scalp lacerations. I have used the traditional HAT trick multiple times but not the modified technique.

What’s the difference?

Instead of using your fingers, the modified approach involves the use of two instrument clamps to help twist and pull the hair strands taut. It turns out that this makes a huge difference, especially for short hairs. The clamps allow you to grab the hair strands so much more securely, before instilling a tissue adhesive at the twisting points.

The nice added benefit was that my chubby fingers were now out of the procedural field. This allowed my assistant to more easily see and reach the hair twisting points with the Dermabond applicator.

Check out the finished product of this 2.5 cm laceration on the scalp vertex.

Bottom line

The simple addition of two instrument clamps provides significantly superior control, stronger tensile strength, and better exposure when twisting hair strands together. Try it.

Paucis Verbis card: Acute limb ischemia

Acute limb ischemia (ALI) is a true vascular emergency. It doesn’t occur as frequently as the more high-profile conditions as cerebrovascular accidents and acute myocardial infarcts, but it portends similarly high morbidity and mortality risk.

How do you stage a patient with ALI, based on the Rutherford classification system?
What is the ED treatment plan?
Should this patient go to Interventional Radiology or the Operating Room for more definitive management?

Trick of the Trade: Prescribing opiates

As emergency physicians, we are experts in pain control. We frequently write opiate prescriptions for patients being discharged home. Unfortunately, an occasional patient tries to forge my prescription. At times, I get a call from pharmacy for prescriptions that were suspiciously written. For instance several years ago, I had someone try to forge 100 tablets of “Mophine”.

YouTube increases limit to 15 minutes

I have slowly been building my video database of instructional media on YouTube under my YouTube Channel called “ITIMEinEM“. It stands for Innovative Technologies In Medical Education in Emergency Medicine. All of the videos have been used in this blog.

Paucis Verbis card: Strep pharyngitis

Have you heard of the Modified Centor Score for strep pharyngitis? Interestingly, it has been validated in adults and children. The methodology builds on the traditional Centor Score by incorporating the patient’s age, because this disease is more prevalent in kids than adults. In fact, you actually lose a scoring point if you are older than 44 years old.

Brain Slides: My new favorite blog

I just encountered a new blog called Brain Slides: Presentation Design for Educators, written by Nathan Cashion. This blog eloquently teaches how Powerpoint should and, more importantly, shouldn’t be used.
