Bone marrow aspiration can provide information on the proliferation of bone marrow hematopoietic cells, cell morphology, etc. Bone marrow bacterial culture in patients with sepsis or certain infectious diseases can improve the positive rate of bacterial culture. In some patients with malignant tumors, bone marrow metastasis can be detected by bone aspiration. It is very important for the diagnosis of various hematological diseases and guiding clinical treatment. The site of bone puncture is mostly chosen at the anterior superior iliac spine, posterior superior iliac spine or sternal stalk of the patient, which will not cause damage to important organs. The pain experienced by the patient is similar to that of a usual intramuscular injection, as local anesthesia is administered during the puncture.
Bone marrow is an important part of the body’s blood production that is renewed daily, and 0.5-5 mL is withdrawn for testing without any effect on the body or damage to the body.
Bone aspiration is not indicated for all patients and has contraindications. Bone puncture is contraindicated in patients with hemophilia, where coagulation factor deficiency can cause local hematomas after puncture. If the puncture site is locally infected with septicemia, it is important to choose another non-infected site for puncture or wait until the local infection is completely controlled before performing bone puncture. After bone puncture, patients may experience mild pain at the puncture site, and local bleeding may occur in patients with hematologic disorders and abnormal coagulation mechanisms, but patients and their families should not be nervous, as the bleeding will stop after 20-30 minutes of compression and the local pain will gradually disappear in 3-4 days. The patient is reminded to pay special attention to keep the puncture site clean and free of water for a week to prevent local infection.
So don’t be afraid to have your bone marrow drawn, meet the indications for the puncture, and take precautions and care after the puncture, and there will be no damage to your body.
