Diagnoses that sound alike

Emergency Medicine is as much about taking care of undifferentiated patients as it is about naming specific signs, symptoms and diagnoses. After 10 years of medical training I’ve noticed that there are a few diseases that require us to stop and think a bit. In particular I’m thinking about conditions that share these features:

  1. They sound-alike, look-alike, or share words or roots of words
  2. They affect a specific organ or part of the body
  3. They have very different etiologies, implications, prognosis and treatment

The two sets of diagnoses that I encounter most frequently with this problem are Mesenteric Ischemia (or Ischemic Bowel) and Ischemic Colitis and Aortic Dissection and Aortic Aneurysm (often manifested in the unlikely “dissecting aneurysm”).

Incorporating debriefing into clinical practice


I’m in the middle of an intense weeklong course on debriefing for medical simulation here in Cambridge, MA. One of the goals many of the participants share is our desire to improve our skills in the art of debriefing after clinical simulations. Although the course focuses on “Debriefing with Good Judgement” 1 today the faculty also offered a simple tool to structure a brief debrief when time is very limited.

Paucis Verbis card: Procedural sedation and analgesia

picture-shark-fin-capnogramFrom time to time, our patients need moderated and deep sedation in order to tolerate painful procedures such as joint reductions or incision and drainage procedures. There are many medications available to us including some newer ones such as Ketofol and Dexmedetomidine.

This week’s Paucis Verbis is a reference card to remind us of the importance of Airway Assessment and help us calculate the medication doses.

If you want to learn more about these medications and some strategies for different types of patients and procedures I recommend the EMCRIT Podcast PSA Lectures 1 and 2.

Paucis Verbis card: Rapid Sequence Intubation

Laryngoscope rapid sequence intubation

The key to success in performing procedures is preparation. This is especially true for endotracheal intubations in the Emergency Department where things are chaotic. Strategic planning and anticipation of obstacles during rapid sequence intubation (RSI) are key principles to avoiding complications.
