[Bone marrow aspiration for diagnostic purposes]

Examination of bone marrow aspiration is an important tool in the diagnosis of haematological diseases. First attempts of bone marrow sampling took place at the beginning of the twentieth century. Thereafter, numerous methods were proposed and different materials were described. The commonly accepted sites for sampling are sternum and the iliac crest. We describe here a sampling procedure for each site. Bone marrow aspiration is a safely investigation, but not recommended for patients with impaired haemostasis. The physician must be aware of its side effects and complications which could occur. The consequence of the complications varies according to the type of iatrogenic injury. Prevention and rapid diagnosis are a crucial point in the management of bone marrow aspiration accidents. To avoid malpractice, the procedure should be taught by senior physicians including theoretical as well as practical learning. The purpose of the learning is a high quality of care to ensure patients the best comfort in subsequent bone marrow examinations, this point being particularly important in paediatrics.
