I second and triple everyone else's seconds on staying with your daughter as much as possible.
I was on a vent in a "semi-coma" for a month. She spent time reading to me, holding my hand, talking to me. When I could communicate, she helped me use a system of letters on a notepad to spell out words I wanted to say since I had a tube down my throat. She never left my side for more than was absolutely neccesary for a LONG time because when she did, my vitals shot all OVER the place....
I don't remember any of this at all, I just know about it because she's told me.
I'm kind of upset about some of that because a few of the books she read to me were by two friends of ours who are pretty well known poets. I like their work a lot and I'm sure it was VERY comforting to me at the time to hear her read.
Ask your daughter what SHE wants.
Ask her before the surgery and then ask her afterwards when she's able to respond. Be sure you do what SHE wants, not what you think she wants. =)
I see your point of not having too many visitors around. Too many people,. even family, can get pretty stressful when you're in recovery and it's best to keep that to a minimum. However, I LOVED having family come by for a visit when they could. When I knew they were coming I looked forward to it, and was dissappointed when they couldn't make it because of weather. I saw some family members I hadn't seen in years simply because they were near Cleveland and knew I was at the Clinic, one cousin brought me a big white lily on Easter.
Having family around means a LOT, it gets pretty lonely sitting in a room by yourself with heart monitors and crummy TV sets blaring....
Even having a nurse around (even when they were doing blood draws or other unpleasant things) was helpful.
