I had my gallbladder out...honestly...worse surgery I have ever had! They ended up giving my dilauded but that was before I got out on the oxys I detoxed from. So don't know what to suggest :( best wishes and praying for a speedy recovery for you!! :))
Best thing to do is to make sure your dr and anesthesiologist know about the suboxone and how much you take as it will affect their decisions in caring for you. I was on a VERY high amount of pain meds and other drugs when I finally got to have my back surgery and that made it difficult to control my post surgery pain. I actually had to be adminstered oxygen 3 times while still in the hospital.
The whole surgery team needs to know exactly what meds you are/have taken to insure your safety. Good luck to you~
