Re: Placental culturesFrom: doctorjoe@aol.comThu Apr 6 11:44:32 2006
You should get both aerobic and anaerobic specimens or you'll miss some important bugs on occasion. If you have a special bug in mind (e.g. GBS, H. flu, whatever), make sure you take an appropriate collection for that, per your lab. To be complete, you should get both sides of the placenta. The maternal side is usually "clean" if the placenta delivers Schultz. I'm not sure that it matters if you dig in between the cotyledons or simply swab the surface. The fetal shiny side will have the same bugs the AF has in it. And if you're REALLY looking for all the info you can get, send the placenta and cord for pathology, looking for signs of funisitis particularly. It was always my feeling that infection USUALLY travels from mother-->placenta-->up cord-->to baby. So if there's funisitis, then you're getting close to a septic baby. Of course, some transcervically spread bugs go directly to the baby without particularly hitting the placenta first.

I have seen it done so many different ways and I have been told that there is a "correct" way to do it. Do you get aerobic and anaerobic swabs? Maternal and fetal surfaces? Between the cotyledons?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
