Tasty Morsels of EM 019

16 Sep

I keep a little, ever-expanding note on my phone where I jot down little morsels of goodness that I pick up while listening to or reading one of the many excellent sites/podcasts in the useful resource section.

I’ll try and transfer them here for your enlightenment.

From the wonderful new Emergency Ultrasound Podcast. In particular episode 3 on dyspnoea and episode 4 on DVT

I’ve done a bit of echo stuff that I taught myself and these guys assume the basics – that you know what the main windows for echo. So this doesn’t cover the absolute basics

  • if anterior mitral valve leaflet does not reach within 7mm of septum then EF likely less than 30%
  • McConnell sign: “wink” in the RV at the apex indicating acute RV overload associated with PE
  • IVC collapse less than 50% indicates cvp > 15

And on DVTs

  • 2 point DVT scan probably all we need
  • covers the really important issue of calf vein DVT – in my opinion generally unimportant – but still no definitive answer on this
  • point for compression is at the take off of the saphenous. I’d previously just been looking at the common femoral. I doubt it’s that important but it does provide a useful marker for the saved images.
