Trick of the Trade: Modified hair apposition technique

I got a nice email from Dr. John Fowler from Turkey who recently published a modified version of the Hair Apposition Technique (HAT) trick in the American Journal of Emergency Medicine in 2009.

Read more about the traditional HAT trick.

The HAT trick allows for scalp laceration closure by using scalp hair and tissue adhesive glue. Contraindications to this technique for wound closure include hair strands less than 3 cm, because it is difficult to manually manipulate short hair.

What do you do in these cases?

A man on coumadin for atrial fibrillation arrives because he has increased bruising on his skin. He is otherwise asymptomatic. He was told to come to the ED because of a lab result showing INR = 6.
A woman on coumadin for atrial fibrillation arrives because of melena and hematemesis. She looks extremely sheet-white pale. Her vital signs are surprising normal. Stat labs show a hematocrit of 15 and an INR value that the lab is “unable to calculate” because it is so high.

Paucis Verbis card: TIA prognosis

Here is another installment of the Paucis Verbis (In a Few Words) e-card series on the topic of Transient Ischemic Attacks (TIA) from EM Clinics of North America. I use this card a lot specifically for the ABCD2 risk-stratification score.

Trick of the Trade: Finger nailbed laceration repair

Over the years, I have been frustrated by how inelegant finger nailbed closure is. Nailbed lacerations are often sustained by a major crush injury, resulting in a stellate and irregular laceration pattern. This typically also requires the crushed fingernail to be removed. Cosmesis is never ideal because pieces of the nailbed are often missing, as seen in the photo above.

Occasionally, nailbed lacerations are caused by a cutting rather than a crush mechanism. In these cases, I use a different technique. I leave the fingernail on. In fact, I use the fingernail to help reapproximate the nailbed edges.

Paucis Verbis Project: A peripheral brain e-card series

A few days I wrote about my “peripheral brain” note cards that I carry with me on each ED shift. These cards contain brief summaries of updated guidelines, evidence based literature, and clinical pearls. I constantly get requests for a copy of them, but they are fairly outdated now that I’m out of residency.

So starting today, I’m going to start periodically posting new note cards in Word and PDF format that can be printed on any 4×6 inch index card. These will be posted every Friday. Feel free to download, edit, change font or font size, and use. You can add/remove cards as you collect them. Comments are definitely welcome.

Paucis Verbis Project

“Paucis verbis” means “in a few words” in Latin. I’ll initially start reviewing new articles from the Emergency Medicine Clinics of North America publication series. This is my favorite review resource in EM. It comes out every 3 months.

My first Paucis Verbis card will be a duo review. The first article is on shock by a super-star friend of mine, Dr. Matt Strehlow (Stanford). The second is first-authored by Dr. Philip Perera (Columbia) on the RUSH Exam and the role of ultrasonography in shock resuscitation.

Tricks of the Trade: Diagnosing retinal detachment with ultrasound

In a sneak peek of my ACEP News’ Tricks of the Trade column, Dr. Patrick Lenaghan, Dr. Ralph Wang, and I will discuss how bedside ultrasonography can significantly improve your ocular exam.

Here is a classic example. A patient presents with acute onset right eye pain and blurry vision. She possibly has a field cut in her vision. Her pupils are a teeny 2 mm in size in the brightly-lit Emergency Department. You are having a hard time getting a good fundoscopic exam to comfortably rule-out a retinal detachment.
