Before the procedure begins, you may be asked if you have any questions and if you have any allergies.
A bone marrow biopsy can be performed as a day case which means that you can go home the same day. Your appointment takes about one hour. Local anaesthetic is always used and Entonox (gas and air) is also available for pain relief.
You will need to remove some clothing and will be asked to lie on a couch.
The bone marrow biopsy is taken from either your pelvis or, very rarely, your sternum (front of your chest). We clean the area with antiseptic solution and a local anaesthetic is injected into your skin, the tissues beneath your skin and the outer layer of your bone. This may sting at first and then the area will go numb.
When the anaesthetic has worked and you are numb, a special needle is used to remove the bone marrow. The needle is introduced through the bone using a special mechanical drill. Both the bone marrow aspirate and the bone marrow trephine are taken using the same needle. When staff have all the samples they need, the needle is removed.
If the procedure is causing you unacceptable discomfort, you can ask for Entonox (gas and air). This may make you feel lightheaded. The effects wear off quickly and it should not delay you leaving the department.
We apply firm pressure to the biopsy site after the procedure and put on a small dressing, followed by a pressure dressing to reduce the risk of bleeding.
If you have had the procedure performed as a day case you will be asked to wait for about 30 minutes. After 30 minutes, the biopsy site dressing will be checked and then you will be able to leave as long as the bleeding has stopped.
You are advised not to drive yourself home. Please arrange to have someone to collect you if no one is accompanying you.
