Finally, got a real night shift.
At one point, I was gowned up holding direct pressure on a spurting radial artery wound after some dude had punched his way through a window. My headset (yes, we wear headsets, and they're only slightly metrosexual) goes off asking me to come to the trauma bay to supervise an airway as we do for any trauma during our second year. I get someone to take over for me and walk down towards the bay, talking on the phone to hand surgery. I don't even know the name of the radial artery bleed, only the room, since I walked in on the heels of EMS. I re-gown for the airway, check the tube and end-tidal CO2, manage vent settings, and while I'm placing an OG tube the radiologist calls me, also on my headset, to tell me about a new cerebellar stroke found on the patient right next to the radial artery bleed.
Despite myself, I smile. This is EM. I realize deep down that it all makes sense. It was the right choice.
Also ran my first PNB over the EMS radio and tubed a drunk lady with a huge laceration of her posterior while wading through the headaches and abdominal pains and two decompensated cirrhotics.
