The side effects of bone marrow puncture on the human body are mainly the following: First, local infection. As the puncture can bring bacteria from the surrounding skin into the soft tissue or bone tissue, it can cause osteomyelitis, or inflammation or abscesses in the surrounding skin subcutaneous tissue. Secondly, bleeding after bone marrow puncture leads to the formation of surrounding subcutaneous blood, or surrounding hematoma. The hematoma is larger, absorbed more slowly, and prone to fibrosis or local calcification, thus having an effect on human activities.
