Last month the AHA, ERC, and ILCOR released the 2010 Resuscitation Guidelines. They build on the 2005 and previous guidelines and continue the trend towards more, higher quality, uninterrupted CPR. The complete summary and recommendations are published in Circulation and are available for free.
Here is my summary for you!
Ingrown toenails, or paronychias, are usually exquisitely painful and a bit gnarly when they present to you in the Emergency Department. Dr. Stella Yiu described toenail splinting techniques using steristrips or dental floss. The purpose of splinting is to prevent the toenail from growing back into the lateral nail fold.
This assumes a relatively mild-to-moderate case. Often simple elevation of the nail out of the lateral nail fold (under digital block anesthesia) is all that is needed to treat a paronychia. Pus is often released with this maneuver.
There’s no toenail to slide the steristrip/ cotton/ dental floss material under.
Emergency physicians are procedural experts in central venous access. The subclavian vein is the best site for such access, because it has been shown to have the lowest rate of iatrogenic infections and deep venous clots
Bedside ultrasonography has really revolutionized how we obtain vascular access over the past 10 years. Identifying the subclavian vein using ultrasonography, however, is still technically challenging. The vein is located just posterior to the clavicle, which often gets in the way of the linear transducer.
It is difficult to determine if a patient with a left bundle branch block (LBBB) has an acute myocardial infarction (AMI) because ST segments are “appropriately discordant” with the terminal portion of the QRS. That means if the QRS complex is negative (or downgoing), the ST segment normally will be positive (or elevated). Similarly if the QRS complex is positive (or upgoing), the ST segment will be negative (or depressed).
In 1996, Sgarbossa et al looked through the GUSTO-1 trial patients with LBBB and AMI. They derived 3 criteria which may help diagnose the “hidden” AMI. The criteria are:
1. ST elevation ≥ 1 mm concordant with QRS complex (most predictive of AMI of the 3 criteria)
2. ST depression ≥ 1 mm in lead V1, V2, or V3
3. ST elevation ≥ 5 mm where discordant with QRS complex
Use these criteria with caution though. None of these criteria are perfect. They are to help you risk-stratify. For instance, criteria #3 (ST elevation ≥ 5 mm) can exist in asymptomatic patients with LBBB because of concurrent left ventricular hypertrophy and high voltages.
There are many ways to relocate a shoulder dislocation. Most of these ways require procedural sedation. What if the risks of procedural sedation outweigh the risks? What alternative maneuver can you try, which only requires parenteral pain medications +/- an intra-articular lidocaine?
To treat for pertussis or not?
In the setting of the current pertussis epidemic in California, each kid with a cough sparks constant debate about whether to treat with azithromycin or not. Finally, thanks to my friends Dr. Andi Marmor and Dr. Shon Agarwal Jain (UCSF Pediatrics faculty), there’s a great algorithm to help you answer the question. I have found this algorithm extremely helpful.
You basically start by risk-stratifying by age and pertussis immunization status. For instance, if the patient is 6 months of age AND unimmunized), then follow the algorithm listed as “High Risk for Pertussis”.

Pediatric patients often receive inadequate pain control in the setting of orthopedic injuries. Because the child experiences fear, anxiety, and pain with needles, practitioners often shy away from ordering IV or IM pain medications. Oral agents, while easier to administer, usually provide inadequate pain control.
Intranasal (IN) fentanyl
Thanks to my friend Dr. Ron Dieckmann (Editor-in-Chief for PEMSoft, Chairman of Board for KidsCareEverywhere, and Pediatric Director for Valley Emergency Physicians) for his tip about intranasal fentanyl:
It is imperative that the drug be administered in a nebulized form using an atomizer device — one half the volume in each nostril. Attach a 1 cc syringe to the end of the atomizer to administer fentanyl intranasally.
It is rapidly absorbed and provides excellent analgesia within minutes. It works just as well as IV morphine (1). If you just drop the liquid in the nose without using the atomizer, the child will swallow some of the drug, and onset and effect will be blunted significantly and titration is not possible.
The starting dose of 1.5 microgram/kg can be repeated in a dose of 0.5-1.5 microgram/kg IN in 5 minutes. Be sure to use extreme caution in younger patients who are more susceptible to the respiratory depressant effects of all opiates; it has not been tested in children < 3 years of age at all, so I would not use in this age group. Put patients on a pulse oximeter. In the event that a child receives the drug and starts to desaturate, bag the patient, then just give naloxone 0.1 mg/kg/dose to a maximum of 2 mg intramuscularly, and the respiratory effects will be rapidly reversed.
