Re: Cord blood for stem cell transplantFrom: CheriCNM@aol.comMon Oct 7 12:26:00 1996
In a message dated 96-10-06 19:53:50 EDT, kmoise@bcm.tmc.edu (Kenneth J. Moise) writes: << The question arose as to whether obstetricians would be willing to routinely harvest this blood at delivery. The apparatus might be as simple as a needle connected to a collection bag with anticoagulant. The umbilical vein would be cannulated and the blood allowed to drain by gravity. Once the cord was drained, the bag would be clamped and sent to a central refrigerator area for subsequent pickup. Blood bank personell would secure consent on the first postpartum day. (Alternatively, the obstetrician could obtain consent during the prenatal course.) What are the list subscribers' opinions on this topic? Would you be willing to participate as the blood collector? >> I've collected cord blood for a commercial cord blood bank at a parent's request. It was a huge hassle, not nearly as simple as the procedure you describe above. The volume requested was quite large and involved the use of three 20cc syringes. This was quite inconvenient, as it had to be done promptly after the delivery, at a time when I am usually involved in the stabilization of the infant, the beginning of maternal/infant bonding, and meeting the emotional needs of an excited family. Not to mention monitoring for signs of placental separation and managing the third stage of labor. If the procedure truly was as simple as cannulating the umbilical vein and allowing the blood to drain into a heparinized bag I would certainly be willing to perform this additional task. One concern I have, though, is that I generally place the infant on the maternal abdomen and allow the cord to stop pulsating before clamping and cutting. I wonder if there would still be sufficient flow through the umbilical vessels to allow cord blood collection if I continued to follow this practice. I do like the idea of non-profit banked cord blood, however. It could be a real boon to the medical treatment of many devastating conditions. Cheri Van Hoover, CNM Kaiser Hospital Redwood City, CA

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.
