REBEL EM-ers: Salim, Jenny and I would like to announce the launch of a new REBEL EM project. Beginning in 2019, we'll be adding a core content section to the website. This will include core content blog posts and a core content podcast with a dedicated place on the parent site. Instead of creating a separate podcast, we'll be bringing you REBEL Core Cast as part of REBEL Cast. This way, you won't need to download another podcast. Twice a month, Jenny and I will bring you a podcast based on a core topic in EM or based on pearls from our conferences. See you all in the New Year!

Friday, 2300 hours:

A 24 year-old woman presents to your Emergency Department after a motor vehicle collision. She was the restrained driver of a car that collided head-on with another vehicle. She is complaining only of chest pain and appears uncomfortable and anxious.  The monitor shows sinus tachycardia and you spot a sternal fracture on her chest x-ray.  After IVF and Fentanyl, she remains slightly tachycardic and you wonder:

  • Do I need to send a troponin?
  • If the troponin is negative does this patient need to be admitted?
  • What other testing should I consider in the Emergency Department?
