Garry, I disagree with your description of the Kjelland forceps. It has a cephalic curve like all the others, but does not have a pelvic curve, which is the angle between the shanks and the blades. That said, I agree with Robert that, although classical teaching was to rotate then replace the blades, there is no need to do that. They are a perfectly good traction forceps; just be aware of the need to lower the handles to achieve axis traction. Nice to know there some other forceps users out there. Maybe we should establish an interest group within ACOG in the (probably vain) hope of resurrecting this noble and time-honored skill. DP At Wed, 18 Feb 2004, Garry E. Siegel, M.D. wrote: >

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.
