Trauma And The Electronic Health Record

I’m going to dedicate this week to discussing the impact of the electronic health record (EHR) on trauma care.

First, I’ll talk a little about the history of the EHR, how it came about and why it was “encouraged” of all hospitals. I’ll also look at who the big players are. Next, I’ll review two studies of the impact of the EHR on ED productivity and patient stay.

And finally, I’ll really dig into using an electronic trauma flow sheet that interfaces with the EHR. My thinking has slowly been changing, but not by much. I’ll review my reasons, and talk about the (few) success stories that are out there.

Stay tuned!

Why Do They Call It: The Surgical Neck of the Humerus?

Anatomy is complex and confusing at times. Pretty much everything you can find in the human body has a name. Sometimes it makes sense. Sometimes it’s named after someone famous. And sometimes, it’s just a head-scratcher.

Let’s take the surgical neck of the humerus. Here’s an image of the proximal humerus:


Notice there are two different “necks” of the humerus. You are probably familiar with the anatomic neck from your anatomy classes. But if you are a resident, an orthopedic surgeon, or someone who deals with fractures regularly, you are more familiar with the surgical neck.

The surgical neck of the humerus is the most common fracture site on the proximal humerus.  But here’s the kicker. It’s a misnomer!

Just because you see a fracture of the surgical neck of the humerus doesn’t meed it needs surgery! Indeed, many of these fractures are now successfully treated with immobilization in a sling. Your friendly neighborhood orthopedic surgeons will assess fracture stability by looking at the mechanism, exact location, involvement of the tubercles, and motion. Then they will decide on their treatment plan.

Bottom line: Don’t get suckered when someone asks you what operation is usually needed for a fracture of the surgical neck of the humerus!

How Fast Can You Warm Up A Hypothermic Patient?

‘Tis the season to see hypothermic patients again! The optimal way to warm them up has been debated for years. A number of very interesting techniques have been devised. Ever wonder how fast / effective they are?

I’ve culled data from a number of sources, and here is a summary what I found. And of course, the disclaimer: “your results may vary.”

Warming Technique Rate of Rewarming
Passive external (blankets, lights) 0.5° C / hr
Active external (lights, hot water bottle) 1 – 3° C / hr
Bair Hugger 2.4° C / hr
Hot inspired air in ET tube 1° C / hr
Fluid warmer 2 – 3° C / hr
GI tract irrigation (stomach or colon, 40° C fluid, instill for 10 minutes, then evacuate) 1.5 -3° C / hr
Peritoneal lavage (instill for 20-30 minutes) 1 – 3° C / hr
Thoracic lavage (2 chest tubes, continuous flow) 3° C / hr
Continuous veno-venous rewarming 3° C / hr
Continuous arterio-venous rewarming 4.5° C / hr
Mediastinal lavage (thoracotomy) 8° C / hr
Cardiopulmonary bypass 9° C / hr
Warm water immersion (Hubbard or therapy tank) 20° C / hr
