What are the steps of bone marrow transplantation

summary

I believe everyone has heard of bone marrow transplantation. In many people's impression, bone marrow transplantation is a very terrible thing. But in fact, everyone has some misunderstandings about it, which is not as terrible as you think. Let's talk about the steps of bone marrow transplantation.

What are the steps of bone marrow transplantation

First: routine examination: assess your general condition through necessary physical examination and some laboratory tests before transplantation, so as to ensure the safety of subsequent transplantation and provide reference for future evaluation. Routine examination, such as routine examination, examination of the function of the nose, ear, and eye, etc.

Second: collection of bone marrow or stem cells: stem cells can be collected from the donor's bone marrow or peripheral blood. If it's autotransplantation, you will be mobilized and collected in advance. Bone marrow is extracted from the donor iliac bone with fine needles, and the stem cell rich bone marrow is stored for transplantation. In the process of collection, the donor is under anesthesia and will not feel pain.

Third: collect peripheral blood stem cells. There are stem cells in peripheral blood, but the number is relatively small. Some cytokines such as granulocyte colony-stimulating factor (G-CSF) and other drugs are needed to increase the number of stem cells in peripheral blood. When the number of stem cells is enough, they can be collected by blood cell separation.

matters needing attention

After bone marrow transplantation, we need to carry out certain radiotherapy and chemotherapy to continue to kill the pathogenic cells in the body, which will also bring a lot of pain to patients, such as nausea, weakness and appearance changes, so patients should persist.
