@riderwayne – I had a left TKR just about one year ago at the Mayo Clinic in Rochester. I too was nervous about the anesthesia. They set me up at my pre surgery meeting (one week prior) to meet with an anesthesiologist to go over my fears and my personal surgery drug plan. I felt really listened to and confident that I would have a successful experience.
While in pre op the anesthesia team came in to assure me that my concerns were addressed and that I would not be put under, but rather awake during the procedure. They also agreed to give me smaller doses (unless i needed more). I recall some diazepam type drug in an IV before they inject some anti pain drug into my leg guided via ultra sound. In the OR they gave me something that put me in an awake, yet not awake and not remembering state. When I got to post op the drug wore off quickly and I was alert and not in the least bit nauseated. I could not remember the procedure nor could I remember how I went in with one gown and came out with a different one. Yikes! I went to my room and a bit later someone came in and had me up and walking. I only took extra strength tylenol during my 24 hour hospital room stay and again never once felt groggy, confused or sick from the surgery.
Fair warning though…..they do inject some type of long lasting pain med right in to the knee area before you leave the OR. I thought I was a tough guy, but in about 48 hours it wears off so make sure you fill your pain med prescription. I ended up taking full doses of Tramodol for 2 days and 1/2 dose for 2 or 3 more and then just a 1/2 dose before bed for about a week with advil/tylanol during the day.
I strongly encourage you to be your own advocate and request to meet with the anethesia team.
Wishing you a life with out pain, Kajon
