There are many
occupational risk factors in
operating room work.
Polymethyl methacrylate (
PMMA) , as a kind of common
bone filling and
repairing material, is widely used in the fixation of artificial
joints, oral
braces and orthopedic
prosthesis. However,
PMMA will release methyl
methacrylate (MMA) monomer when it is implanted into
human tissues and polymerized to harden, which is toxic to the body. This
paper analyzes harmful factors in using
PMMA bone cement, and then explores corresponding occupational
protection knowledge, in order to reduce the occurrence of
occupational hazards related to
PMMA bone cement and enhance the
self-
protection ability of the operation room
medical staff.
