Know more about the bone marrow aspiration procedure
The bone marrow aspiration will be done in the operating room and by an experienced doctor.
A bone marrow aspiration is usually done at the back of one of your hipbones, in an area called the posterior iliac crest. However, in some cases, the aspirate fluid can be taken from the breastbone or from the front of the iliac crest near the groin. In babies and young children, the aspirate may be taken from the lower leg bone, just below the knee.
For the aspiration, a hollow needle is inserted through an incision and on through the bone and into the bone marrow cavity of your iliac crest. Because local anesthetics aren't able to numb the interior of your bone, you may feel a deep, aching pain when the needle is fully inserted.
A syringe is used to draw a sample of the liquid portion of the bone marrow into the hollow needle. As the liquid is drawn up, you may feel a painful stinging, sucking or pulling sensation, which may travel down your leg. The aspiration takes only a few minutes. You may need to have several samples taken.
Your medical team checks the sample to make sure it's adequate. If it is, the needle is removed.
After your bone marrow aspiration, a large pressure bandage is applied to help minimize bleeding.
If you had local anesthesia, you may have to lie on your back for 15 to 30 minutes to apply pressure to the biopsy site. You can then leave and go about your day, returning to normal activities as soon as you feel up to it.
Keep the pressure bandage on and dry for the next 24 hours. Don't take a shower or a tub bath and don't swim or use a hot tub. After 24 hours, it's OK to get the biopsy area wet and to replace the pressure bandage with a regular adhesive bandage.
A small amount of bleeding is normal. However, if bleeding soaks through the bandage or doesn't stop with direct pressure, contact your doctor as soon as possible.
