I had one gig once years ago where you might get a few hours of sleep. I worked a lot of nights by the end of my EM days (*prepandemic.)
Freestanding. Sweet setup.
And then one night I actually was asleep and a crashing, bradycardic 99% LAD STEMI came in by private vehicle at 5am.
Took me a full minute to wake up and grasp what the nurse was yelling.
Couldn't get the STEMI cardiologists on the phone, couldn't get the cath lab activated, it was a cluster nightmare. Ended up calling the ER at the mothership and giving them the heads up that I was lights-and-sirening a disaster their way.
She lived and did well, but it ruined the place for me.
And even though I did occasionally get nights where I could lie down, I never managed to sleep-sleep there again.
I was not an inherently anxious person, but I was after that night.
(And FWIW, I got a ton of pedi airways in training, thanks to a single solid pedi anesthesia attending who made me really learn. I bagged a kid through a whole cardiac procedure. I tubed a bunch of kids... one three times while he yelled "do not intubate the toes!" and yanked the tube back out when I went too deep. It was safe, controlled and made me rock steady because at that hospital, we saw every Make-A-Wish kid who got sick on their Disney trip.)
But I am also old, and do not envy you all on the "other side."
(Of both medicine, and at the beginnings of your careers.)
