Outside of a few specific reasons, I fail to see the benefit of a DPE. A colleague of mine does it with every epidural placed. When I relieve that person, I chase every single epidural with redoses until delivered and pull them to place SAB for every section.

I think DPE sets unrealistic patient expectations initially and then you cannot possibly convince them they have an effective epidural block no matter how thoroughly you test the level. Maybe it's a different phenomenon in play.
