No, it says that it must be *over* 140 systolic or 90 diastolic. And as has been pointed out, we've only been given this one reading. It's likely that the bp was taken many times per day over this 3-day period. It's not very likely that it went higher without Garry mentioning that fact.

I did not say that.

Right. Of course, that's also true for somebody who goes into labor with platelets of 200K. So, following your logic, we should assume that every patient is about to drop her platelets, so we have to intervene now.

I was always taught that one needed to make a diagnosis before instituting treatment. Silly me.

Right. So again, we'd better just do sections on every patient, since any of them might suddenly become thrombocytopenic.

Right. So why are you supporting intervention for preeclampsia when it is "unclear" whether she had it? Would you recommend mastectomy and chemotherapy for a patient if you were "unclear" whether she had breast cancer?

Consensus is not very persuasive to me.

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.
