Wendy, your AFI (4 quadrant, vertical sum) of less than 6 cm is the method most often used today. However, the use of the AFI in multiple gestations is more controversial. I think the sonographer/sonologist subjective evaluation for multiples is the best way to go... usually comparing the fluid in the two sacs, rather than trying to empirically measure it.

Dear Colleges: I currently work for a practice of 7 Ob/gyn's. Each have there own idea what our cut off should be and how to acquire the AFI. I was taught to measure the largest vertical pocket free of cord and fetus in 4 quadrants. Currently I am using the AFI under 6 as oligohydraminos and I would not give the 2 points in the BPP. Some of the docs feel as long as there is one pocket 2 cm x 2 cm this is acceptable and 2 points should be rewarded. I am seeking the current guide lines set forth for determining AFI and oligo. I am also interested in the technique used for twins or multiples. I know this seems basic but I am just trying to set a standard protocol for our office. Thanks in advance. Wendy M. Zamkoff RDMS

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.
