EM Critical Care Publication

3:00 AM in education, guest post, hot off the press

Hot off the press!

A new CME publication has emerged from the publishers of Emergency Medicine Practice and Pediatric Emergency Medicine Practice called EM Critical Care. This new publication is specifically geared towards manging critically ill patients in the ED. There will be 6 issues per year with each issue offering 3 AMA PRA Category 1 credits. Although it has not yet been released, it appears to have an impressive editorial board including Emanuel Rivers, Michael Gibbs, Benjamin Abella and Robert Arntfield. Oh, and did I not mention Scott Weingart from the EMCrit Blog? If it is anything similar to it's predecessors, it is guaranteed to be a hit!

Check it out here.

Don't forget from a previous post that Emergency Medicine Practice articles from 2007 and earlier are free online. That post can be found here.

Disclosure: I have no financial ties to the above mentioned publications. I'm just a satisfied subscriber.

Hot off the press: Clinical practice guideline for ketamine in the ED

3:00 AM in article review, education, hot off the press, pediatrics

A 3 year old girl is brought into the ED with an abscess to her groin. Upon examination it is fluctuant and needs incision and drainage. Next door is a 5 year old boy, who fell off his bed and has an angulated radius fracture that needs reduction.

Hhhmmmm...how to manage these patients? Local anesthesia? Hematoma block? Nothing (aka brutacaine)? What about ketamine, that seems popular these days. IV? IM? With or without atropine? So many decisions!

Luckily you were surfing the internet one night and came across the 2011 clinical practice guideline on ketamine in the ED, which was just published.

This practice guideline was updated from a previous 2004 version because of new research that proved/disproved the way ketamine was being utilized. It was compiled by four physicians that are experts in the field of ketamine sedation, two of which wrote the 2004 practice guideline. Updated research was found by performing a MEDLINE search from January 2003 to November 2010 using the search term "ketamine".

Highlights:

1. Adults have been included in the 2011 guidelines.

2. Adjunctive medications

• Prophylactic ondansetron can help reduce vomiting. The number needed to benefit = 9.
• No need to co-administer atropine or glycopyrrolate for oral secretions.
• Prophylactic midazolam 0.3 mg/kg may prevent recovery reactions in adults (but not children). The number needed benefit = 6.

3. Contraindications

• Age < 3 months because of risk of airway complications
• Known or suspected schizophrenia (even if currently stable)
• Head trauma has been removed as a contraindication.

4. Route of administration

• IV administration appears to be preferred over IM, because of faster recover and fewer episodes of emesis.
• IV route: Peak concentration and onset = 1 min, duration of dissociation = 5-10 min, time from dose-to-discharge = 50-110 min
• IM route: Peak concentration and onset = 5 min, duration of dissociation = 20-30 min, time from dose-to-discharge = 60-140 min 

5. Complications

• Laryngospasm has been reported to be around 0.3%. What do you do when this happens? You'll just have to read this previous post to find out.
