Bone marrow aspiration is a medical procedure used to collect a sample of bone marrow, which is the spongy tissue inside some of your bones, such as your hips and thighbones, that produces blood cells. This procedure is essential for diagnosing and monitoring various blood-related disorders, including leukemia, lymphoma, and multiple myeloma. As a crucial diagnostic tool, bone marrow aspiration provides valuable information about the production of blood cells and helps healthcare professionals determine the effectiveness of treatments.
The procedure involves inserting a needle into the bone marrow cavity to extract a sample of the marrow. This process can be uncomfortable, so it's typically performed under local anesthesia to numb the area. The most common site for bone marrow aspiration is the posterior iliac crest, which is the curved part of the pelvis at the back.
Bone Marrow Aspiration: Purpose and Preparation
The primary purpose of bone marrow aspiration is to obtain a sample of bone marrow for examination. This examination can reveal abnormalities in the production of blood cells, such as a decrease or increase in the production of certain types of cells. It can also detect the presence of cancer cells, infection, or inflammation in the bone marrow.
Before undergoing bone marrow aspiration, patients are usually advised to inform their healthcare provider about any medications they are taking, especially blood thinners. Patients may also be asked to fast for a certain period before the procedure. The procedure is typically performed in a hospital or clinic setting by a trained healthcare professional.
Step-by-Step Procedure
The bone marrow aspiration procedure involves several steps:
- The patient is positioned on their stomach or side, depending on the site chosen for the procedure.
- The area is cleaned and numbed with a local anesthetic.
- A needle is inserted into the bone marrow cavity.
- A syringe is attached to the needle, and a sample of bone marrow is aspirated (sucked out) into the syringe.
- The needle is removed, and pressure is applied to the site to stop any bleeding.
- A bandage is applied to the site.

- Patients may experience discomfort, pain, swelling, and bruising at the site after the procedure.
Post-Procedure Care and Complications
After the procedure, patients may experience some discomfort, pain, swelling, and bruising at the site. These side effects are usually temporary and can be managed with over-the-counter pain medication and rest. Patients are advised to avoid strenuous activities for a few days after the procedure.
While bone marrow aspiration is generally a safe procedure, there are potential complications, including infection, bleeding, and nerve damage. Patients should seek immediate medical attention if they experience severe pain, swelling, or bleeding at the site, or if they develop a fever.
Interpretation of Results
The results of bone marrow aspiration can provide valuable information about the production of blood cells and the presence of abnormalities, such as cancer cells or infection. A healthcare professional will interpret the results and discuss them with the patient.
The results may indicate:
- Normal bone marrow production
- Abnormal bone marrow production, such as a decrease or increase in the production of certain types of cells
- Presence of cancer cells
- Presence of infection or inflammation
