I think some of ours do, although I can't prove it.
The other night when I had a PPH r/t retained frags, they came in & did a manual removal (mentioned in another thread -- no pain meds :angryfire ). After all was said and done (and blood was everywhere), the EBL (of the PPH) was 300ml. Uh, I don't think so.
Not when a wad of clots almost the size of a volleyball comes out -- not including what we'd already expressed before they got there.
I should've weighed the chux to see how much blood there was. 300ml my big toe.
