After BMT
( 2 items )
After the transplant takes place, a new phase of the BMT process begins. All attention is focused on helping the patient to recover from the effects of the transplant conditioning and from the introduction of the new brand immune system from the donor. If all goes well, infections and side effects will be able to be kept under control. and the patient's body will accept the transplanted marrow or stem cells, a process which is called engraftment. Waiting for engraftment, partiuclary for patients who recieve BMTs from unrelated donors, is a very challenging time. Most patients will be hospitalized during this period, and until their condition is stable enough that they can be followed on an outpatient basis at the transplant center.
