Anaphylaxis occurs on a spectrum. Although anaphylactic shock is a well defined form of distributive shock, your patient does not have to have “shock” to have “anaphylaxis”.

Add 0.01 ml of 1:1,000 epinephrine per ml of lidocaine.
- 10 ml of lidocaine would need 0.1 ml of 1:1,000 epinephrine
- 30 ml of lidocaine would need 0.3 ml of 1:1,000 epinephrine
We keep 5 and 30 ml vials of lidocaine in the ED. To make 30 ml of 1:100,000 lidocaine with epi, draw up 0.3 ml of 1:1000 epinephrine with a tuberculin or insulin syringe and inject into the 30 ml vial. To make 10 ml, use two 5 ml vials. Inject the 0.1 ml of epi into one of the 5 ml vials of lidocaine, then draw up both 5 ml vials of lidocaine into one 10 ml syringe. Voila.

Ventricular Tachycardia and adenosine
Supraventricular Tachycardia with abnormal conduction (“aberrancy”) is often difficult to distinguish from Ventricular Tachycardia. The 2015 AHA guidelines on the management of adults with SVT state that the presence of AV dissociation (i.e., the presence of P waves visible among the QRS complexes at a rate slower than the ventricular rate) or fusion/capture beats “provides the diagnosis of ventricular tachycardia.” Other criteria are suggestive, but not confirmatory. Diagnostic algorithms – Brugada or Vereckei for example, are complicated and can be difficult to apply.
Continue readingRoll Call
At the beginning of resident conference each week, we run through a list of common problems you might in encounter in the ED. It’s ‘open book,’ but is supposed to go really quickly – the whole list should take less than 10 minutes. Here is that list – the “roll call.” At this point we have 2 lists: one has general medicince / toxicology items, the other has EKG tidbits. We will alternate these every month or so and may add another one with antibiotics or whatever else seems to fit the format. Get familiar with it. These are things you will use for the rest of your life.
How to follow the blog
For any non-blog-savvy folks (of which I am one), the simplest way to follow the blog is to click the “follow” tab that shows up in the bottom right corner when you open a page. No need to create a wordpress account – just enter your email address. Then you will receive an email with a link to confirm. Click it, and that’s it. You will get emails whenever a new post is added. For whatever reason, the “follow” button goes away as you scroll down a page but comes back if you scroll up.
Stitches
Here is a video about some of the common mistakes we see learners make. It’s not “how to tie a knot,” but rather some of the other steps in the process. It’s not exciting. It’s a little too long. I get it, but I bet there is something in it that you didn’t know you didn’t know.

You only need one sedation to go awry to realize that this is an area where an ounce of prevention is worth a pound of cure. We have an informal checklist you should use to make sure you have thought of every potential complication and planned for it accordingly. This particular checklist was made in-house and has not been formally validated. However, it was made after reviewing similar checklists from other departments, and it has been approved by our ED staff as well as anesthesia. Use it. It wards off evil spirits.
