Upon admission to the Bone Marrow Transplant Unit, a countdown period of usually five to 10 days begins. Day 0 marks the end of the countdown and the day of transplant. During the countdown period, one of the conditioning regimens is administered. This involves treatment with chemotherapy agents and possibly radiation, called total body irradiation.
Patients stay in a special BMT room with a bed, television, VCR, phone, sink and private bathroom with a shower and bath. It is a special room that provides a positive pressure environment in which only highly purified (HEPA-filtered) air is allowed to enter. The room is cleaned every day, and everyone who enters the room must follow specific procedures to minimize complications associated with the transplant process. Visitors to the BMT Unit must follow certain rules that protect the transplant recipient and help our program run smoothly.
All visitors — including doctors, nurses, other members of the health care team and family members — must wash their hands before entering and leaving the room. In addition, there is a clean outer room, called an anteroom, that separates the patient's room from the hallway. The doors to the anteroom and patient room are kept closed at all times thus maintaining the positive pressure environment. This isolation policy is intended to minimize the risk of developing an infection during the transplant process. Transplant patients must stay in their room, except for when they need radiation therapy or occasional tests or procedures that can only be done elsewhere, until the new marrow has begun to work. The total amount of time in the Transplant Unit varies, but generally it is six to eight weeks.
There are several routines that are done daily or several times a day to minimize those problems that may occur during the bone marrow transplant process.
Antibiotics and medicines are given throughout the transplant period to reduce irritation of the stomach and intestines and prevent certain kinds of infections that frequently occur in a transplant recipient. These medications are continued until isolation is stopped, although some may be discontinued if your child is started on intravenous antibiotics because of fever or other signs of infection during the isolation period — while the neutrophil count (ANC) is less than 500. The daily medications include:
