Hello, during a total knee replacement today, a huge clump of hair was discovered in the bottom of a tray of trials. I immediately called the tray contaminated, along with the entire back table. An argument ensued and I was told that the hair went through the sterilizer therefore it is sterile. I was always told that you could not sterilize hair via heat sterilization because it is a protein. Maybe nuts, but I wanted to be safe and do what was best for the patient. Unfortunately, the patient was already on the table...had to tear down and wait for the instruments to be redone. In the room at 7:28 and started at 11:01!! What is your opinion.
