Generally, after the bone marrow puncture, the patient should rest in bed for about half an hour, and if there is no obvious adverse reaction, he can get out of bed normally. Also, after the bone marrow puncture, the puncture site should not see water for 24 hours to prevent infection. Bone marrow aspiration is the most common test in hematology. In hematology, bone marrow aspiration is needed to confirm the diagnosis of almost all diseases and to determine the effectiveness of the treatment of diseases, so it is performed almost every day. Although bone marrow aspiration is an invasive test, it is relatively less traumatic. If a clinically experienced doctor performs bone marrow aspiration, the patient will hardly feel any pain, there will be a little slight pain at the beginning of anesthesia or a little slight soreness when the bone marrow fluid is extracted, but the rest of the time there is no pain, so the patient does not need to be nervous to have a bone marrow aspiration.
