Bone Marrow Donation Videos.

Ok so you’ve given your saliva sample to be tissue typed. What happens if you are found to be a suitable match for one of the thousands awaiting a transplant?

There are two methods of bone marrow donation.

Method 1   Peripheral Blood Stem Cell Collection (PBSC)

About 80% of donors donate via this method.

Prior to stem cell collection donors are given injections to increase the number of stem cells in the blood. More than 10,000 unrelated donors have been given these injections worldwide to date with no long term side effects reported.

The collection itself involves the donor lying on a hospital type bed in the out patients clinic. Blood is drawn out of one arm and fed into the cell separator (apheresis) machine. The machine centrifuges the blood, separating the blood stem cells from the other blood components and the stem cells are collected in a blood bag along with some plasma. The blood re-enters the donor’s blood stream via the other arm.

This process is an outpatient procedure known as apheresis and no general anaesthesia is required.

Hotel accommodation will be arranged for the donor if they live far from the collection centre.

Method 2   Bone Marrow Harvest.

The remaining 20% donate via this method.

Bone marrow is extracted from the pelvic bones or sternum under general anaesthetic by sterile disposable needle and syringe in an operating theatre in a process known as a ‘bone marrow harvest’.

The donor is admitted to hospital for 2 nights, one before and one after the harvest, and three days. Usually the donor is able to return home from hospital 24 hours after donating.

The vast majority of donors decide to undergo a general anaesthetic, but there may be valid reasons why a spinal or epidural anaesthetic may be preferred.

No surgical incisions or stitches are made but several puncture marks will be made in the bone and therefore the skin.

All donors will be seen by a doctor before discharge and are required to visit their GP a month post donation for a full blood test.

The bone marrow removed in the harvest is regenerated in the normal manner within a few weeks and as far as is known there are no harmful effects in this intervening period.

The experience of previous donors indicates that it is not an unduly painful process.
