I don’t know how big your center is or the capabilities and motivation of the anesthesia department. But standard of course is a general anesthetic (go to sleep) but ask if a brachial plexus block is possible. It should be placed before you go to sleep. You’ll wake up with a numb shoulder and parts of the arm; the catheters can be left in up to a couple days.

If placed early and done right the pain will be greatly reduced even after everything wears off.
