we've got a local drunk at my institution who comes in 3-4 times a week near intubation for drinking excessively.
She was in about a week and a half ago, got intubated for an EtOH of .552, got sent to the ICU, then extubated herself 5 hours later, left AMA, took a taxi to the bar, and came back to the ED 6 hours after that, with an EtOH of .524
This is a consistent thing for her....and it's sad, and nobody knows what to do with her.
We were actually taking bets the other day on how she'd die (likely aspiration or ruptured varix), and then she promptly arrived no more than a half hour after that hovering in the low .5's.
