There are procedures that last longer than that.
I can see not wanting to hand off to another team in the middle of a procedure (because it’s not just the physician/surgeon, it’s the scrub nurse/tech, the circulating nurse/tech, etc.) but at some point, it is definitely in the patient’s interest to at least consider it. I’ve seen procedure teams get called into a complex case 11 hours and 30 minutes into their shift. It’s not good.
