The Health Hazard Evaluation Program received a request from employer representatives at a hospital. They were concerned about the potential for noise-induced hearing loss (NIHL) among operating room employees performing total knee replacement surgeries. We visited the hospital to observe total knee replacement surgeries, learn more about the equipment and tools used, and measure noise exposures of surgical staff. A typical surgical team included a surgical assistant, anesthesiologist, circulating nurse, scrub nurse, surgeon, and, possibly, a surgical fellow. Powered surgical tools were the primary sources of noise in the orthopedic operating room and noise levels were highest during surgical procedures. One surgeon's personal noise exposure exceeded the NIOSH recommended exposure limit on one day we monitored, but all other personal noise exposure measurements were below all occupational exposure limits. On the basis of our noise measurements and our estimates of noise exposures for surgeons, we found that they could be overexposed to noise depending on surgery length, shift length, and number of surgeries in a shift. We recommended including orthopedic surgeons in a hearing loss prevention program, using quieter surgical tools, and providing surgeons with flat attenuation ear plugs or noise cancellation earmuffs.
