Do your OBs underestimate EBLs?

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. :uhoh3:

Everybody underestimates blood loss. Multiple studies have been done on this and it seems every time the practitioner is way off on the actual loss. Here is one study on midwives and physicians.

EBL is Estimated blood loss

PPH is postpartum hemorrhage

EBL = estimated blood loss

PPH = post partum hemorrhage

our docs do that all the time......

I was in a c section where they soaked about 45 laps and called the EBL 300mL.....the suction canister had about 800 mL in it! (i know that some of the fluid in the canister was irrigation fluid and amniotic fluid but patient was being sectioned for fetal intolerance to labor due to oligo)..... Hmmmmmm......

I had PPH after delivering my DD last year....read the 'birth report' and EBL was 1100cc - I didn't receive a blood transfusion- I'm not sure what my H&H was, but all I know is I passed out, don't remember much of the hours following the birth. But I've always been curious - in OB RN opinion, how severe of PPH is that considered? Dr. didn't act like it was that big of deal....

p.s. disclaimer...not asking medical advice just nursing opinion!

They underestimate blood loss, and over score APGARS. Human nature to make yourself look "good", I guess.

I was in a workshop on management of PPH and they said that nurses tend to overestimate and docs to underestimate. I wish I could remember the source for it but I can't find it, sorry.

The only 10s I've seen were given by paramedics in the field. :lol2:

We gave apgars of 10 to infants of OB staff. :)

At a certain EBL the chart may get reviewed by peers, prompting the practitioner to lowball the estimate. Perhaps when he was called on it he would say "whoops, I meant 3000, forgot the zero."
