If any of you guys have a good system with regards to treating the post-op pain in TKA's I would like to know it. Currently, I do a Continuous FNB pre-op bring them to the room for a spinal with 0.4 mg duramorph and 10mg bupiv. and then depending on the surgeon (length of case) put them to sleep or sedate them. I think that going to sleep is over kill but it is needed for some of my surgeons. THe CFNB runs for 2 days at 8cc/hr of 0.2% ropiv. This is the best thing that I have come up with but it is alot of different procedures which I don't mind cause they only take a few minutes anyway. Just curious as to how others may be doing these cases.
