During On transplant day, donors arrive at the hospital and are put under general anesthesia. During the procedure, the donor is on their stomach and bone marrow is retrieved from the back part of the pelvis. Two physicians draw out the bone marrow simultaneously—one on each side of the donor—through special needles. About teaspoons of marrow is drawn out at a time.
Paquette says. The process takes about 2 hours from start to finish depending on the size of the recipient and the amount of marrow required.
After Donors either spend the night in the hospital or go home the same day. After the procedure, donors may have a little bruising and the area may be sore and tender to the touch. Others say it feels like they fell on their backsides. But it's usually not painful unless you put direct pressure on the area where the needles were inserted," says Dr.
In the weeks after transplant, Sheldon's healthy bone marrow set up shop in Alan's system and began making new blood and building a higher-functioning immune system.

The machine collects blood-forming cells, platelets and some white blood cells. Plasma and red blood cells are returned to your body through the other arm. All the tubing used in the machine is sterile and is used only once for your donation.
If only one donation is done, it may take up to eight hours. If two donations are done on separate days, each collection will take four to six hours. Donors may experience headaches or bone and muscle pain, similar to a cold or the flu, for several days before collection.
These are side effects of the filgrastim injections that disappear shortly after donation. Other common side effects are nausea, trouble sleeping and tiredness. Less than one percent 0. The PBSC donation procedure can also have side effects. Some donors experience tingling around the mouth, fingers and toes and mild muscle cramps. This is caused by the anti-coagulant blood thinner used in the apheresis procedure.
These symptoms are easily treated with calcium replacement or by slowing down the procedure. Other common side effects include bruising at the needle site, chills and a decrease in the blood platelet count.
PBSC donation may require placement of a central line if you do not have suitable arm veins. A central venous line is a sterile tube that is inserted into one of the larger veins — the femoral vein, internal jugular vein or subclavian vein. The risk of serious complications from use of a central line is small. A central line will be placed only with your consent after you have received information about the possible risks. Another potential risk is associated with filgrastim injections. Though filgrastim is commonly used to treat cancer patients, the use of filgrastim in healthy donors is fairly new.
Therefore, no data are yet available about the long-term safety. We began using filgrastim to aid in transplants in the s. Since then, no donors from the registry have reported any long-term complications from filgrastim injections. Before the donation, you will receive five days of filgrastim injections. The first must be given at a donor center or medical clinic, and the fifth will be given at the location where you will undergo the donation procedure.
The injections on days two through four may be given at your place of work, your home, at the donor center or a medical clinic. If your recipient's transplant center is in the U. However, each country has different rules about giving updates. If your recipient is at a transplant center in another country, you may never receive an update or updates on your recipient.
During the first year after transplant, some centers allow anonymous communication between you and your recipient. Some centers allow direct contact between donors and recipients one or more years after the transplant, if both you and your recipient consent.
Some centers do not allow you to have contact with your recipient at any time. While transplantation is a life-saving therapy, not all recipients survive.
Sometimes a patient's body cannot withstand the pre-transplant chemotherapy and radiation. Sometimes health complications occur after the transplant. But for many recipients, a transplant is successful and their best or only option. Your gift gives them hope and a second chance at life. Donation FAQs Need help deciding if donating bone marrow is right for you? How is a bone marrow match determined?
How likely is it that I will match a patient and go on to donate? What happens if I match a patient? Can I change my mind? How are bone marrow and peripheral blood stem cell PBSC donation different? Who pays for the donation process? How long does donating take? What if I have medical complications related to the donation? What is the bone marrow donation process like? These will go away after the donation. If you want to donate stem cells, you can talk to your doctor or contact the National Marrow Donor Program, a federally funded nonprofit organization that keeps a database of volunteers who are willing to donate.
If you decide to donate, the process and possible risks of donating will be explained to you. You will then be asked to sign a consent form. You can choose to sign or not. You won't be pressured to sign the form.
After you agree to be a donor, you'll have a test called human leukocyte antigen HLA typing. HLAs are proteins found in most cells in your body. This test helps match donors and recipients. A close match increases the chances that the transplant will be a success. If you sign up with a donor registry, you may or may not be matched with someone who needs a blood stem cell transplant. However, if HLA typing shows that you're a match, you'll undergo additional tests to make sure you don't have any genetic or infectious diseases that can be passed to the transplant recipient.
Your doctor will also ask about your health and your family history to make sure that donation will be safe for you. A donor registry representative may ask you to make a financial contribution to cover the cost of screening and adding you to the registry, but this is usually voluntary.
Because cells from younger donors have the best chance of success when transplanted, anyone between the ages of 18 and 44 can join the registry for free. People ages 45 to 60 are asked to pay a fee to join; age 60 is the upper limit for donors. If you're identified as a match for someone who needs a transplant, the costs related to collecting stem cells for donation will be paid by that person or by his or her health insurance.
Collecting stem cells from bone marrow is a type of surgery and is done in the operating room. You'll be given an anesthetic for the procedure. Needles will be inserted through the skin and into the bone to draw the marrow out of the bone.
This process usually takes one to two hours. After the bone marrow is collected, you'll be taken to the recovery room while the anesthetic wears off. You may then be taken to a hospital room where the nursing staff can monitor you. When you're fully alert and able to eat and drink, you'll likely be released from the hospital.
If blood stem cells are going to be collected directly from your blood, you'll be given injections of a medication to stimulate the production of blood stem cells so that more of them are circulating in your bloodstream. The medication is usually started several days before you're going to donate. During the donation, blood is usually taken out through a catheter in a vein in your arm.
The blood is sent through a machine that takes out the stem cells. The unused components are returned to your bloodstream.
