Purpose of the procedure:
To obtain marrow (core of the bone from where blood cells are
produced)
General Information about the procedure:
This procedure is done to get sample of bone marrow for analysis.
Usually this procedure is done as a second line test after examining
the blood. If there is a problem in the peripheral blood and,
diagnosis can not reached from the blood test bone marrow is done
to confirm the diagnosis.
Bone marrow is usually done for blood disorders like anemia, decreased
white blood cells, decreased platelets, or abnormal increase in
the above cells. It is also done to rule out or confirm hematological
(blood) malignancies. Bone marrow is also done to confirm certain
infection like typhoid fever, malaria, kalaazar etc.,
When & Where the procedure will
be done and how long will it take?
This procedure is done usually as an in patient, during any time
of the day. Preparation: Part of the body where the procedure
is planed is to be cleaned and hair removed. Patient need not
be in empty stomach. Informed consent has to be taken.
Description of the procedure:
Usually sternum (chest bone) or posterior ileac spine (hip bone
on the back) is selected. Rarely tibial tuberosity (below the
kneecap) is selected. Skin over the site is cleaned with antiseptic
solution local anesthetic agent is injected to decrease the pain
and with the help of specialized aspiration needle outer layer
of the bone is piearsed and marrow aspirated. PAIN is usual when
aspiration is done.
Potential Risk, if any: Pain
is usually present. If sternum is selected for aspiration then
there is potential risk of injuring the underlying major blood
vessel. But with due precaution this risk is very low. If iliac
bone is selected there is no major risk involved, as there are
no major structure underlying the bone. But iliac bone some time
bone marrow sample may not be adequate.
Instruction after the procedure:
Patient to be in bed rest for at lest 6 to 12 hrs. If the procedure
is done in the iliac bone pt should avoid walking for at least
one day. To keep the procedure site clean.
