I just had my second AVR on 3/2. I had this surgery at UAB but I had a terrible experience in CVICU. Per the Dr.'s orders, I could not have "anything" for pain until I had been off the respirator around and hour. I could not slow my breathing down to an acceptable rate to remove the respirator (I think it was because I was in such severe pain) so I ended up not getting anything for pain well into the second day after my surgery. I have been though a lot of pain in my life time but this was definitely the worse. Always make sure with your surgeon before the surgery what the plan of care is for controlling your pain.
THAT is awful, I can't imagine how I would have acted if my son was treated like you were. BUT it is really good advice to talk to your surgeon about pain care before surgery, we ALSO discuss pain control with the Anesthesea team when we have the preop test day and meet everyone. I'm sorry you had to go thru that, it sounds horrific, did you have your first surgery there?
