This was indeed the claim, because there were more caesarean sections in the 'monitoring' group. However a third of these were induced anyway, for various reasons and according to the protocol this group was ineligible to receive prostin for ripening the cervix. Also, the increase in CS was for 'distress' only, not for dystocia and could be simply due to a different threshold for intervention in a study which by nature cannot be 'blind'. Not a good trial to base induction protocols on - even if an RCT involving lots of centres.

In any case at over 41+ weeks it is more likely that a pregnancy is misdated than really that far post dates (see our abstract in Ultrasound Obstet Gynecol 1996;8:Suppl 1, p 212).

This does not alter the fact that the case which started this thread ought to be delivered, IMHO.

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.
