Re: Seeking for further studiesFrom: Terry DuBose (terrydubose@sbcglobal.net)Sun Aug 14 16:24:07 2005
You stated that the two machines are using the "same hadlock measurement", but you are not getting the same result. Is that correct. By "same hadlock measurement" do you mean the outer abdominal circumference, femur length, BPD, & head circumference? Hadlock published several fetal weight estimates... are you sure the algorithms use the same Hadlock formula? You will need to look at the users manual for each machine to determine which Hadlock publication and which forumula is used. This is an interesting problem of sonography because there have been so many formulas published for the various parameters. Please let us know what you find. Thanks, Terry ebrillo@kingdomhospital.com wrote: i have a querry regarding the standard efw formula, how effective and accurate is efw for ob us how come if i use THE GE MACHINE we have here9GE 400/ge 700) I COULD GET EFW closed to weight the fetus when delivered but if i used envisor philipps there is a very big descrepancy more than 500 grams same hadlock measurement pls/kindly explain to me i even ask the engener of phillips

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.
