Re: EFW accuracyFrom: DuBose, Terry (DuboseTerryJ@uams.edu)Wed May 21 09:40:14 2008
I suspect the reason sonographic measurements are considered so questionable is that there are so many people using sonography who do not have rigorous training and do not practice precise methods. Many seem to think precise measurement methods are not necessary because "ultrasound" is not considered accurate, a sort of self-fulfilling problem. In a lawsuit in which I was an expert witness, a case very similar the one under current discussion, the sonographer has attended an unaccredited, short course of study, was not credentialed by the ARDMS, and was on-call by herself. It was obvious she had measured the abdominal circumference at the ribs and spine in back, completely excluding the skin, baby fat, and muscles in back. The vaginal delivery also ended up with dystocia and neurological damage in the neonate. It is my opinion that sonography, in the hands of a skilled sonographer, is much more accurate than it is given credit for being. But many simply do not take the time and/or do not have the understanding and skill to use it effectively. I would like to see how the measurements in the case under current discussion were actually made. We also need to be moving to volumetric measurements, the fetus does not live in "Flat Land"... and the head molds considerably, especially in the vertical axis due to the sutures and fontanels.

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.
