“Mad as a hatter.”
The term actually comes from the toxicity hat makers would develop from exposure to mercury fumes in the 1800s. So, what does this have to do with surgery? Recently Liz Kowalczyk’s “No More Surgical Caps for Surgeons?” September 1, 2016, Boston Globe discussed the anger some surgeons have had over new hospital policies regarding surgical caps worn in the operating room.
For years, most surgeons have worn a surgical cap that sits above the ears. Most are disposable, but some are custom made or personalized cloth caps. I have a Spiderman cap and a cap with musical notes all over it. The concern more recently has been the amount of hair left uncovered, and the potential risk of infection from this hair.
