Every hospital and surgeon is different. and many procedures vary from hospital to hospital. As a matter of fact, some things are changing so rapidly that one of the nurses in the pre-surgery area jokingly replied to my question about this weird blowing warm disposable "blanket" on my gurney, that that was supposed to help keep germs down (I think that was her explanation) so they were using them...then she added with a grin, "this week anyway". I asked her how they keep up with all the changes lately, and she said it's not too hard as long as she doesn't take more than a couple of days off. She was joking, but I think there was some truth to her joke. I've had a lot of surgery and some things have been noticeably different each time. (For instance, just a couple of years ago the usual stay at my hospital after a TKR was 3-4 days, now most patients go home the same day)
