title: [Collection of umbilical cord blood to separate the peripheral blood stem cells during the third stage of labor].
abstract: In order to collect the umbilical cord blood for the separation of peripheral blood stem cells, obstetrician have to get the document of informed consent from the pregnant women for the umbilical cord blood donation during pregnancy. After the fetal delivery, umbilical cord blood is easier collected from the umbilical vein of the placenta in utero than that of the delivered placenta. After the sterilization of umbilical cord, the special bag attached with tube and needle is more useful to collect the blood disinfectively and abundantly than the syringe. Blood stem cells should be separated as soon as possible after collection, but umbilical blood may be stored in the refrigerator until 24 hours after the collection, if the immediate separation is impossible. There is the positive correlation between the collected blood volume or the preserved hours until the separating management and the separated stem cells. Hearing on the health of the child should be followed until 6 months after delivery.
