Yeh i watched it really made mevery sad.Imagine your life depending on the generosity of people willing to give a bit of themselves.
@Jett i understand your concern i really do, and i don't blame you... but i hope you'll do a bit more reaserch on the subject,never know you might findthat saving a persons life might be worth the risk?
Here is a bit of info reagrding treatment and risks involved.
1.How is bone marrow obtained for transplantation?
The stem cells used in BMT (Bone marrow transplantation) come from the liquid centre of the bone, called the marrow. In general, the procedure for obtaining bone marrow, which is called “harvesting,� is similar for all three types of BMTs (autologous, syngeneic, and allogeneic). The donor is given either general anaesthesia, which puts the person to sleep during the procedure, or regional anaesthesia, which causes loss of feeling below the waist. Needles are inserted through the skin over the pelvic (hip) bone or, in rare cases, the sternum (breastbone), and into the bone marrow to draw the marrow out of the bone.
Harvesting the marrow takes about an hour. The harvested bone marrow is then processed to remove blood and bone fragments. Harvested bone marrow can be combined with a preservative and frozen to keep the stem cells alive until they are needed. This technique is known as cryopreservation.
Risks associated with donating bone marrow?
Because only a small amount of bone marrow is removed, donating usually does not pose any significant problems for the donor. The most serious risk associated with donating bone marrow involves the use of anaesthesia during the procedure.
The area where the bone marrow was taken out may feel stiff or sore for a few days, and the donor may feel tired. Within a few weeks, the donor’s body replaces the donated marrow; however, the time required for a donor to recover varies. Some people are back to their usual routine within 2 or 3 days, while others may take up to 3 to 4 weeks to fully recover their strength.
How are PBSCs (Peripheral Blood Stem Cell) obtained for transplantation?
The stem cells used in PBSCT come from the bloodstream. A process called apheresis or leukapheresis is used to obtain PBSCs for transplantation. For 4 or 5 days before apheresis, the donor may be given a medication to increase the number of stem cells released into the bloodstream. In apheresis, blood is removed through a large vein in the arm or a central venous catheter (a flexible tube that is placed in a large vein in the neck, chest, or groin area). The blood goes through a machine that removes the stem cells. The blood is then returned to the donor and the collected cells are stored. Apheresis typically takes 4 to 6 hours. The stem cells are then frozen until they are given to the recipient.
Risks associated with donating PBSCs?
Apheresis usually causes minimal discomfort. During apheresis, the person may feel light-headedness, chills, numbness around the lips, and cramping in the hands. Unlike bone marrow donation, PBSC donation does not require anaesthesia. The medication that is given to stimulate the release of stem cells from the marrow into the bloodstream may cause bone and muscle aches, headaches, fatigue, nausea, vomiting, and/or difficulty sleeping. These side effects generally stop within 2 to 3 days of the last dose of the medication.
