This information sheet explains the various tests your child will need to prepare for a bone marrow transplant (BMT). It also explains a little about what to expect when your child comes to Great Ormond Street Hospital (GOSH) for these tests and introduces you to the members of the BMT team.
We need to prepare for your child’s bone marrow transplant (BMT) by examining his or her heart, kidneys, lungs, ears (hearing) and teeth. This allows us to identify any health issues so we can make sure that your child is in the best possible health before the BMT. As part of the preparation, we will also arrange for you and your child to meet the team who will be caring for you throughout your hospital stay and after you go home.
The BMT preparations usually takes place over two days, as there are too many investigations to fit into one day. You could either come up for a day on two separate weeks or two days in the same week. We will try to work around your needs if at all possible, but it is very important that we complete all these tests.
What tests will my child need?
The following give a guide to the tests your child will need. If you have any questions about any of them, please ask your nurse.
All children need an echo, which is an ultrasound scan of the heart. It shows the structure, function and blood flow through the heart.
All children need an ECG, which shows how often and how regularly the heart is beating as well as the size and position of the heart’s chambers.
All children need a chest X-ray, which gives a picture of the lungs using a low dose of radiation. It is exactly the same as X-rays of other parts of the body.
Only children aged over one year need to have a dental check to see if there is any decay or infection that might need treatment before the BMT. The dentist will also explain about mouth care during and after the BMT.
Audiology (hearing) tests
All children have hearing tests, although young babies might only have basic tests. These show if your child has any hearing problems before the BMT, as some medicines given during transplant, such as antibiotics, can affect hearing. These hearing tests are repeated one year after the BMT.
Generally only children aged over five years have these tests, although if your child has had previous lung problems, he or she may have lung function tests even if under the age of five. Four tests are used to measure the size of your child’s lungs and airways. The first involves breathing gently through a tube. The second test involves your child blowing out as hard and fast as possible into a tube. For the third test, your child will need to sit in a cabin for a few minutes while his or her breathing is measured. The final test involves your child breathing in two types of gas (neither of which is dangerous) so that the amount of each gas breathed out can be measured.
GFR (Glomerular Filtration Rate)
Children who have previously had kidney problems or who are having a medicine called melphalan have this test, which shows how well the kidneys are working. A dye is injected into a vein and a series of blood samples are taken over a few hours to see how well the kidney filters out the dye. Your child will not be able to eat certain foods during the test as they can greatly affect the test results. These include: tea, coffee, fizzy drinks, chocolate, ice cream or bananas.
Chest CT scan
If your child has previously had chest problems, he or she will need a computerised tomogaphy (CT) scan. This uses X-rays and a powerful computer to build up a picture of your child’s chest area. The scan can take anything between five and 20 minutes depending on the area to be scanned and the level of detail required. Your child may need to have this carried out under sedation or have a general anaesthetic if he or she will not be able to lay still.
Your child may may also need a cannula inserted, even if he or she already has a line. The contrast needs to be given through the cannula so that the picture is clear and cannot be given via the central line.
All children have a full blood screen carried out before the BMT to find out if there are any problems with liver or kidney function. Your child’s blood group, full blood count and clotting levels are also checked, as are specific viruses. A member of the BMT team will explain further about the various blood tests needed.
Total Body Irradiation (TBI) planning
If your child needs TBI as part of their conditioning regime, he or she will need to go to University College London Hospital (UCLH) for this as we do not have a Radiotherapy department at GOSH. You and your child will have an appointment with the consultant radiologist who is specialised in giving TBI, to discuss the process in detail with you. There will also be a second appointment to have a CT scan to take precise measurements of your child, discuss the exact plans for the regime and to meet other members of the team, such as the play specialist.
All your child’s preparation tests, including liaising with the donor registries if needed, are organised by the Outpatient Nursing team. The progress towards transplant and your child’s condition will also be discussed on a regular basis by the medical staff and other members of the BMT team. During this time, your first point of contact will be the BMT outpatient clinical nurse specialist. When your child is admitted for his or her BMT, the Outpatient team will hand over your child’s care to the Inpatient team. Once your child has had his or her BMT and has been discharged home, the Outpatient team will take over your child’s care once more.
Tests for donors
Sibling donor aged less than 16 years
If your child’s brother or sister is the matched donor, he or she will also need to have some tests to check that he or she is fit and well enough to donate bone marrow. These will include an ECG and chest x-ray (explained above) and also a general medical examination. Blood tests will be carried out and one of the clinical nurse specialists will discuss the donation procedure with you and your donor child. Each sibling donor also has to undertake an assessment by an independent person to ensure they are not getting coerced into being a donor. This is to meet the Human Tissue Authority regulations. We understand that this can be a worrying time for your donor child and some further preparation might be helpful if he or she is anxious or scared. We can arrange for him or her to see our play specialist and/or psychologist to discuss any concerns and work through any worrying feelings.
We will attempt to find a bed for the donor the day before the bone marrow is collected and, if at all possible, on the same ward as your other child. However this is not always possible. Therefore the donor will be seen in Outpatients for blood tests before the procedure and for a check up by a doctor. Afterwards, he or she will either go home or stay in the patient hotel before returning as a day case for the procedure. We will tell you where your donor child is likely to be admitted as soon as possible so you can make arrangements. Generally, your child will be well enough to go home the afternoon after the bone marrow donation.
Adult related donors
As GOSH is a children’s hospital, we cannot collect bone marrow or stem cells from adults here. The adult donor will have his or her treatment at University College London Hospital (UCLH), which is about 15 minutes’ walk from GOSH. The tests done at UCLH will include an ECG, chest X-ray and blood tests. The BMT clinical nurse specialists will liaise with the team at UCLH and let you know details of when and where to go.
If your child has an unrelated donor, their bone marrow registry will contact the donor to find out if they are available for the date(s) we have requested. This process can take several weeks and although we understand that this can be a very stressful time, we are not able to influence the donor’s availability in any way. As you appreciate, the donor is not always available to donate on the first requested date due to prior commitments, but the team are in close contact with the donor registries and will inform you as soon as a date is confirmed. Donors have to have a full medical carried out around two weeks before their cells are collected to ensure they are fit to undergo the procedure. There is a small possibility that the donor will fail this and the transplant will not be able to go ahead using this donor.
Members of the BMT team
This section explains about the various members of the BMT team, their responsibilities and when you are likely to meet them.
Once a donor has been identified for your child but before the preparation tests have been done, you will meet your child’s consultant. This is so all aspects of your child’s BMT can be discussed and any questions you have answered. The consultants work on the ward on a rota, so your child may have more than one consultant in charge of his or her care during admission. However, all the consultants work very closely together and will discuss your child’s ongoing care and treatment during weekly ward rounds. All three consultants in the BMT team attend the weekly BMT clinic. As well as the consultants, there will be other members of the medical team caring for your child.
Inpatient clinical nurse specialist
Our inpatient clinical nurse specialist is a member of your child’s Inpatient Nursing team along with staff on the ward. There are currently 10 beds on Fox Ward and three on Robin Ward. We also carry out transplants in a bed on Butterfly Ward as well. Your clinical nurse specialist will tell you which ward your child is likely to be admitted and liaise with the ward sisters.
Your clinical nurse specialist will meet you and your child before you come for the BMT to discuss briefly what being an inpatient will be like. It is a chance for you to discuss any further questions you have about family care, visitor restrictions and any other thoughts. Once admitted for transplant, they will prepare you and your child for the transplant, which includes taking consent for the procedure and talking through how to care for your child once he or she is in isolation. After the BMT, when you and your child are ready to go home, they will make sure that you have all the information needed to take care of your child. In addition, they will liaise with your Community team, shared care hospital and family doctor (GP) to make sure that they are fully informed of your child’s progress and the care he or she will need.
The ward sister for the ward where your child is having their transplant is also a member of your child’s Inpatient Nursing team. They lead and manage the Ward team to make sure that we deliver the highest standards of care possible in the most efficient way. You can discuss your child’s care with the ward sister or any member of the Nursing team. They can also provide support and advice with any aspects of your child’s inpatient stay, the care and treatment your child will receive and any social issues that might arise during admission. The ward sister is also responsible for making sure that the ward environment is kept clean and well maintained so please talk to them about any concerns or questions.
Outpatient clinical nurse specialists
Our outpatient clinical nurse specialists coordinate all outpatient treatment and are the first point of contact for families with a child waiting for a BMT or who have had a BMT. Their role includes discussing care with the medical and nursing teams at your child’s shared care hospital and also with your child’s Community Nursing team. They will organise all your child’s care and treatment, with the aim that your shared care hospital provides as much care as possible with the expertise and experience of the team at GOSH available when needed. Depending on your child’s recovery, you may be with our team for six months to two years after transplant. Once your child has no transplant-related complications, he or she will be transferred to the medical and nursing team who referred your child originally and they will continue to coordinate his or her care.
Specialist nurses also work with the Outpatient Nursing team on a rotational basis. He or she will be involved in most aspects of your child’s care, that is, organising the preparation tests and talking to you about the transplant process. You may also see our specialist nurse during inpatient treatment as he or she also works some shifts on the ward.
Other members of the BMT team
Social workers and family support workers aim to reduce the stress of illness and the experience of staying in hospital. They can provide practical advice and assistance to children and families, including advice on welfare, benefits and financial support.
It is important that your child is as well nourished as possible for the BMT as this will help him or her feel better and may help to fight infection. Before the BMT, the dietitian will assess your child’s diet and check his or her weight and height. If your child is on a special diet or has tube feeds or supplements, please tell us beforehand so we can arrange for these to continue. If needed, the dietitian can discuss your child’s nutrition with you and suggest ways of increasing the amount of goodness in what he or she eats. You will also be able to ask any questions about the ‘clean diet’ and nutritional support before and during the transplant. When you are staying on the ward, the dietitian will visit regularly.
Our occupational therapist (OT) is also part of the BMT team. If your child is aged less than five years, our OT will meet you to discuss your child’s development. Together with the play specialist, they will monitor your child’s development, providing activities and recommendations to help him or her to continue to grow and learn while in hospital and once you return home.
If your child is older than five years, the OT and play specialist will work together to keep your child as independent as possible when it comes to everyday things such as washing and dressing. They will also provide a daily routine for while your child is in isolation and once you go home to make sure that he or she returns to activities suitable for his or her age. If your child needs any special equipment, such as a wheelchair or splints, while staying in hospital the OT will arrange this.
Our play specialist will provide appropriate preparation for your child both before and during the BMT process using picture books and dolls. This will help ease any anxiety your child has about what will happen and give them a clear understanding of what a BMT involves. Our play specialist will also help keep your child developing as normal using regular play sessions and learning opportunities.
A member of the psychology service may meet with you and your family before the BMT takes place. We recognise that going through the BMT process is a stressful time and meeting the psychologist gives you all the opportunity to think about how the process might affect different members of your family and what support might be needed to help you all through it. Children aged five or more will also meet a member of the psychology service to have a short assessment to check his or her developmental progress. Children under five years old will be offered a developmental review with our OT. This helps us monitor your child’s progress throughout the BMT process and help us to advise ward staff on appropriate activities for your child.
