Bone marrow puncture needle examination is a few grades of pain

Bone marrow puncture is 1-2 grade pain. The grading of pain is generally more common in patients with cancer pain, because it is graded by a digital grading method, from 0 to 10, 0 is no pain, and 10 pain is very serious, which is almost intolerable pain. Bone marrow aspiration is generally used to diagnose blood system diseases, and bone marrow aspiration is performed under local anesthesia. If the periosteum is fully anesthetized, most patients have almost no pain or slight pain. If the pain according to the numerical method is about 1 grade and the duration is short, it can be tolerated. Some people are more sensitive to pain due to individual differences, or have problems with the technique during the puncture. The patient may suffer from pain at night so that he cannot sleep. At this time, the pain is level 2. This situation is a special case and generally rarely happens.
