Procedure for Bone Marrow Biopsy

Doctors generally choose hip bone for the process. The chosen site is cleaned with antiseptic or alcohol. After cleansing a sterile towel is placed around the area. Local anaesthetic is injected with the help of tiny needles at the site. After few minutes the site becomes numb. After this a needle is placed through the skin and into the bone. Patients may feel a pressure sensation. For the aspiration of the bone marrow a little amount of bone marrow is pulled into a syringe. After this a somewhat larger needle is then placed in the same site and a small sample of bone and marrow is taken in that needle. Pressure is applied for some minute as the wound site may bleed a small amount. After the process a sterile bandage is applied. You will be given some medicines to relax.
