it's always better to ask forgiveness ...than permission.
to my knowledge there's no "you can't" I'd stealth do it though...
the only company I've heard of is Shell Oil..and probably some of the other chemical plants..have a no smoking and no Electronic Cigarette policy. I'm sure the hospitals will catch up..
but I'm in and out of them all the time and stealth vape. Ed's a lil more out in the open with it that I am..at his friend's bedside but only once was he told rather jokingly by the nurse "you can't do that in here"...so keep it on the down low and it should be fine..if you're in a private room get your doc to write an RX for it..and don't blow it in the nurses faces..(just like old smoking in your hospital room days) then no problems.
If you're to have anesthesia I'd try to make sure you're breathing really good before attempting it..pneumonia's already a risk after surgery..don't worsen it..depending on your condition..get a good hour or so of breathing w/o oxygen and coughing on your own and vape on ..no problems.
