Our surgeons, particularly hepatobiliary, started asking for TAPs instead of epidurals on various open cases a few months back. They are semi- understandably annoyed with the hassle and problems and time associated with epidurals. Block time, sedation, post-op hypotension, need for extra fluid, weakness, etc etc.
My group was skeptical at first- TAPs for a Whipple? But they're only for somatic pain below the umbilicus, right? Why would we do a weak-ass block that won't even cover the incision?
We started doing them, on select patients. Crispy, old, scoliotic, vasculopaths, anticoagulated, insanely anxious, etc etc - the kind you'd expect even a great epidural to be a big PITA. I must say, I'm surprised at how effective TAPs can be, especially subcostals +/- rectus sheath blocks. Doing them all with Exparel and a lot of volume, preincision.
I'm not at all surprised at how variable they are.
I'm also surprised at how variable post-op pain from the same surgery is. Maybe I shouldn't be.
The initial experience has been good enough that the plan for now is to keep selecting patients who seem like good or bad epidural candidates.
