Can i leave my piercings in for when having spinal fusion surgery for scoliosis?

Better out: In the end it is up to the surgeon, anesthesiologist and hospital policy, but all things considered, it is best to remove all jewelry, dentures, glasses, and the like. Removable things can come loose and get lost. In the case of metallic object, they can conduct electrical current and cause burns (for example, the cautery used to control bleeding uses electrical current).

No: Obviously it depends where the piercings are. Or nursing and anesthesia may have separate policies regarding this, over riding what your surgeon says.
