Scrub Nurse
A scrub nurse works in the sanitized area of the surgery. He is "scrubbed in," putting on sterile masks and clothing before approaching the surgical station. The scrub nurse hands the surgical tools and other supplies to the doctor performing the operation. A scrub nurse maintains the sanitation of the operating area, making sure everything stays sterile to reduce the likelihood of contamination. Scrub nurses are also responsible for the care of the surgeon. If her glasses are foggy, or if she is sweating, the scrub nurse is in charge of taking care of those problems, allowing the surgeon to continue her work unhindered.
