Discussion on bone marrow aspiration

No matter in clinical or online consultation, many patients are afraid of bone marrow puncture. As a clinician, I certainly understand that, because it is after all "bone marrow puncture", the word bone marrow is so important and sacred in people's minds, and many people are naturally associated with paralysis and inability to walk.

Patients' fear and resistance to bone marrow aspiration also bring certain difficulties to doctors' diagnosis and treatment. As a hematologist, today is a brief introduction to the bone marrow biopsy.

The purpose of bone marrow puncture is to further understand the operation of bone marrow hematopoietic conditions. In clinical practice, chest puncture, abdominal puncture and waist puncture are collectively referred to as one of the four major puncture, which is a basic skill that every clinician must master during practice. It can be seen that the importance of bone penetration and the difficulty coefficient is not high, the operation process is generally about half an hour, or even less time. Usually, the puncture site is posterior iliac, which is usually said to be the most prominent part of the hip bone. It is relatively safe here, without large blood vessels or important organs. Local anesthesia after disinfection, puncture, puncture needle through the subcutaneous tissue, periostum to reach the bone marrow cavity, extract a small amount of bone marrow smear, of course, according to the needs of the disease may also extract the appropriate amount of bone marrow fluid, the bone marrow fluid smear is equivalent to a finger a drop of blood so much, extraction of bone marrow fluid process and blood drawing process is similar, a few milliliter of bone marrow fluid is equivalent to our human blood test to draw one or two tubes of blood, What would a tube or two of blood do to our bodies? There are only so many overall bone piercings, and how complicated and frightening you think it can be. It is not as exaggerated as people imagine paralysis and inability to walk.
