What Is A Bone Marrow Puncture Needle Used For? Is It Serious? Does It Hurt?

Many people are very scared when they hear that a bone marrow examination is required, and mistakenly believe that the bone marrow examination has a great impact on the human body. In fact, this understanding is wrong. "Bone puncture" is an abbreviation for bone marrow aspirate. The vast majority of human skeletons are "hollow" and filled with bone marrow. Even the "solid" bones like the skull and ribs have loose bone marrow in them. "Bone puncture" is for the purpose of diagnosis. A puncture needle is used to penetrate the bone marrow cavity, and a small amount of bone marrow is extracted for testing. Some patients mistakenly believe that the extraction of bone marrow fluid from bone marrow aspirate will damage the essence of the human body and damage the vitality, and are reluctant to carry out the examination. The total amount of fluid is about 260ml. It can be seen that the bone marrow fluid extracted during the bone marrow biopsy is insignificant compared to the total amount of the human body, not to mention that a large number of cells are constantly regenerated in the body every day. In addition, patients often think that bone marrow biopsy is painful and fearful, but this is actually unnecessary. The most commonly selected site for "bone piercing" is the ilium, which is located on the lower and outer sides of the abdomen, that is, the protruding part on both sides of the lower abdomen. This operation generally needs to be performed under local anesthesia and will not damage large nerves and blood vessels, so it will not cause major bleeding or neuromuscular paralysis. When the bone is pierced, the doctor will strictly disinfect it so that it will not cause osteomyelitis. The operation of bone marrow examination is very simple. Generally, the whole process of bone marrow puncture only takes a few minutes. Some patients feel sore and feel no pain at the moment when the bone marrow fluid is extracted. It is not even as painful as the general intravenous injection. Generally press for 3-5 minutes to get up and move. "Bone piercing" has no danger and will not leave any sequelae. Some diseases, especially some blood diseases, are difficult to diagnose without this test. If the disease requires it, it should be done without hesitation. Even if the bone marrow does not have any lesions, it is a great gain, because the exclusion of blood diseases can not only relieve the mental burden, but also save the patient and family from receiving unnecessary treatment. possible side effects.
