KidsCareEverywhere-Vietnam study findings: SAEM 2012 meeting
I recently had the pleasure of presenting our KidsCareEverywhere-Vietnam team's study findings at the national SAEM meeting in Chicago. Bottom line Despite knowing English as a second language, Vietnamese physicians were able to easily navigate an English-based, clinical decision support software (PEMSoft) after only a brief 80-minute training session, conducted by non-physicians. Their post-test exam scores improved by 84%!
Trick of the Trade: Stabilizing mandibular relocations
Three weeks ago, I talked about more safely reducing mandibular dislocations. After successful completion of the procedure, how do you make sure that the patient doesn’t re-dislocate the mandible? You definitely should tell the patient to keep their jaw closed as much as possible for the next 24 hours and avoid opening the mouth widely (eg. yawning/laughing). How do you immobilize the mandible? Especially for the chronic dislocators, presumably with more lax TMJ ligaments, you should think about immobilization. This can be done with a head bandage which goes under the chin. You can use kerlix rolls or an ACE [+]
SAEM 2012 meeting and social media
Those of us active in social media had quite an active meeting at the Society for Academic Emergency Medicine meeting in Chicago, IL this past week. First off, Dr. David Marcus (@EMIMDoc) from Long Island Jewish Medical Center, NY gave many of us blogs a kind shout-out. Also, many "iReporters" were on scene to live-tweet various events. Take a look at some of the posts below. Click on #SAEM12 hashtag to see the whole Twitter feed. I remember hearing that there were over 600 tweets! https://vimeo.com/42020417
Trick of the Trade: Bend the IV angiocatheter
You identify a great external jugular (EJ) vein to cannulate for IV access. You are having a hard time keeping the angle of the angiocatheter aimed at a shallow angle because the mandible is in the way. This is typical of patients with chubby necks (eg. pediatric patients) or who are unable to rotate their neck. [+]
Paucis Verbis: Genital Ulcers
A few months ago, American Family Physician published a nice review article on the diagnosis and management of genital ulcers. How do you remember the classic appearances of the lesions? I often quickly check references to confirm my suspicions. I find the two following tables helpful to remember. The table of differential diagnoses is from AFP. The article also reviews the confirmatory diagnostic testing and treatment protocols. The table of the clinical characteristics for the main infectious causes is from "The Practitioner’s Handbook for the Management of Sexually Transmitted Disease". Note: Although the primary lesion from Lymphogranuloma venereum (LGV) can have [+]
Trick of the Trade: Seldinger chest tube technique using bougie
A 40 year-old man presents with a traumatic hemopneumothorax. He weighs 400 pounds. Chest tubes can sometimes be challenge, especially for those with extra redundant tissue to tunnel through before reaching the intrathoracic cavity. You want to avoid placing the chest tube mistakenly in the subcutaneous space. How can you ensure that your chest tube actually reaches the intrathoracic space? [+]
TED video: The happy secret to better work
If you have a few minutes, take a listen to this rather humorous and thought-provoking TED video about the "intersection of human potential, success, and happiness". The speaker, Shawn Achor, is the CEO of Good Think Inc, a Cambridge-based consulting firm which researches positive outliers -- people who are well above average, and author of "The Happiness Advantage". “If we study what is merely average, we will remain merely average.” https://www.youtube.com/watch?v=fLJsdqxnZb0
Resuscitation 2012 conference
What are you doing the rest of this week? Hop on a plane to Las Vegas and join me at the 2012 Resuscitation conference. It looks to be a great conference. I'll be giving a 3-hour (!) discussion session on "Tips and Tricks in Emergency Medicine" on Friday. Inevitably when I given this talk, I always come away with great ideas from the audience. I'll be sure to write them down and share on the blog.
Trick of the Trade: Protecting your thumbs in mandible relocations
Does anyone think that this is generally a bad idea when closed-reducing mandible dislocations? Yes, it's easiest to apply downward pressure on the mandible by pushing down on the occlusal surfaces of the molar teeth. Sometimes, however, when the mandible relocates into place, the teeth clamp shut abruptly - placing your thumbs at risk. How can you prevent any injuries to yourself? One way is to slide gauze into the mouth during your procedure. Start the video around the 1:30 mark for an exam. Trick of the Trade: Mandible Relocations Apply a protective roll of gauze over each thumb. [+]
Paucis Verbis: Blunt Abdominal Injury, Likelihood Ratios
This month's issue of JAMA addresses the question "Does this patient have a blunt intra-abdominal injury?" as part of the always-popular Rational Clinical Examination series. The systematic review of the literature summarizes the accuracy of findings for your blunt trauma patient in diagnosing intra-abdominal injuries. Specifically, likelihood ratios (LR) are summarized. These LRs can be used to plot on the Bayes nomogram below. You draw a straight line connecting your pretest probability and the LR. This yields your posttest probability. The most predictive positive LR include: Abdominal rebound tenderness, a "seat belt sign", ED hypotension, hematocrit < 30%, AST or [+]
