Trick of the Trade: Incision and loop drainage of abscesses

Abscess Packing Hand

Why are we still teaching the traditional incision and drainage approach to simple abscess drainage? They require frequent, painful packing changes to ensure persistent drainage of retained pus.

Trick of the Trade

Incision and loop drainage (I&LD) technique

As per usual, Dr. Rob Orman (ercast) beat me to this. He already reviewed the technique on his blog in 2010. This stems from a landmark article in the Journal of Pediatric Surgery, which involves creating a persistently draining fistula at two points by using a small vascular loop, tied into a non-tensile loop.

It makes sense to extrapolate and use this technique for both pediatric and adult patients with uncomplicated abscess, especially if the patients may not follow-up for packing changes as scheduled. The added benefit is that showering is encouraged to help encourage drainage without the risk of dislodging the secured loop.

Questions

Does anyone have experience with this that they would like to share? Particularly, what if you don’t have the skinny vascular loops in your Emergency Department?

What are the follow-up instructions?

Per the Tsoraides article1:

  • Take a bath/shower TWICE daily for the first 3 days.
  • Remove the loop in 7-10 days (when the drainage stops and the overlying cellulitis resolves)

Paucis Verbis: Overanticoagulation and supratherapeutic INR

I find it amazing that I know more non-emergency physicians virtually in the social media world rather than in person. Primarily through Twitter, I follow and am followed by medical educators from various specialties. If you haven’t joined Twitter yet, I think it might be time. There is a whole world of collaboration and conversation going on in this virtual community, which crosses specialties and geography.

Last week, Dr. Javier Benítez (@jvrbntz) was tweeting a Question of the Day, referencing a 2010 Paucis Verbis card on overanticoagulation, which was based on the 2008 American College of Chest Physicians (ACCP) guidelines. About 8 minutes after I retweeted his question, Dr. Roy Arnold (@cholerajoe), a pulmonary/critical care physician kindly informed me that the 2012 ACCP guidelines have been out since February.

So this PV card is replacing the 2010 card with revised recommendations. For more in-depth discussion, definitely take a look at Dr. Scott Weingart’s great podcast over at EMCrit. He helps to clarify holes which the 2012 ACCP guidelines don’t really address such as:

What if the patient is minorly bleeding with a high INR?

  • Oral vitamin K and 15 mL/kg FFP

What if you only have the 3-factor PCC (factors II, IX, X) and not the recommended 4-factor PCC (factors II, IX, X plus factor VII)?

  • If PCC is indicated, add recombinant factor VIIa or FFP to the 3-factor PCC to cover for factor VII.

Welcome to the blog team: Bryan Hayes, PharmD

Bryan Hayes Circle SMHave you been reading the mind-blowing pearls on Twitter by Bryan Hayes, PharmD, DABAT? He is taking world of ED pharmacology and toxicology by storm on Twitter as @PharmERToxGuy. If have not been following him, you are missing out. I usually end up hitting “favorite” for all of his tweets to review again later. So for purely selfish reasons, I asked Bryan to see if he’d be willing to expand his 140 character gems on this blog. Much to my delight, he said yes!

Sort me! Paucis Verbis cards now catalogued

After much recent feedback on the poll about the Paucis Verbis cards (thanks to all who responded!), I see trends:
  • Several have commented that it is getting increasingly difficult to find a card that they are searching for. There are over 100 cards now! So, I managed to figure out how to embed a Google Doc spreadsheet into the blog, which now allows you to sort and search for particular cards (minor HTML coding necessary). This list will permanently live on the Paucis Verbis page.

Poll: Is anyone using the Paucis Verbis cards?

FeedbackFeedback is essential for continued growth and improvement in any longitudinal project that you work on.

Thus annually, I conduct a poll to see if I can improve anything on the blog. This year, I wanted to focus on the Paucis Verbis pocket cards. There are over 100 cards now, which are each based on recent peer-reviewed publications. I try to make them as practical as possible with the goal of improving evidence-based practice at the bedside.
