I'm not sure what the visiting hours were in ICU, I think 8a-8p. After surgery they let my entire family come into ICU - husband, daughters, son-in-law, brother and close friend. They were all there when I was waking up, then I dosed on and off for quite some time.
When I left ICU on day 3, I was on the cardiothoracic floor, which was only open-heart surgery patients, heart transplant and lung transplant patients. There were no visiting hours, 24 hours a day if the patient wants. All rooms were private with a sofa, so my husband even stayed the night. The first few days I was pretty wiped out and could have used less visitors. I was in the hospital for 6 days, so the last few days I did not have too many visitors and was a bit lonely. I think if I was able to read it would have been great-I just had trouble concentrating.
By the way, I had posted about when my son should see me and my husband actually brought him to the ICU. He was such a brave little man and to this day is very careful about hugging me and checks on me and asks me if I'm doing ok. He did great and I think because he couldn't really understand everything that was happening made it less freightening for him.
It was the most difficult for my 20 year old daughter. She really had trouble with the see me with the vent tube. So I would suggest that you may want to limit who comes into ICU until the tube is removed.
Best of luck to you on your surgery. You will be in my prayers.
