Bone marrow puncture is a few grades of pain

Pain is divided into five degrees in the World Health Organization, from 0-IV degrees, 0 degrees does not require special treatment, a kind of pain that can be completely tolerated. The pain of bone marrow puncture is not as severe as everyone thinks. It may be slightly more painful than a skin needle, because the needle needs to be drilled into the bone to get the bone marrow blood out. Generally, local anesthetics, such as lidocaine, are given before the puncture. Local anesthesia will block the nerve pain. Generally, everyone can tolerate it.

The specific scale may be between Ⅰ-Ⅱ degree, no need to give other special drugs to relieve pain.
