Surgeon's caps that expose small amounts of the ears and hair are not inferior to the bouffant-style, disposable scrub hats that cover those features, one of the first studies testing the effectiveness of different operating room (OR) head coverings in preventing airborne contamination has found.          

          For their study, the researchers tested three common styles of commercially available surgical headgear. Disposable shower cap-like bouffant hats underwent testing, as did two types of surgical skullcaps, another name for the tie-in-the-back, close-fitting caps that are popular with surgeons: disposable caps with paper sides, and freshly home-laundered, reusable, cloth skullcaps.

            Unlike most tests for environmental quality, which Dr. Markel said are typically done in a static laboratory, their airborne contamination testing was performed in an actual OR under changing conditions. For each style of hat the OR team wore, they performed a one-hour mock operation, which included gowning and gloving, passing surgical instruments, leaving and reentering the OR, and performing electrocautery on a piece of raw steak to generate particles that were discharged into the air. Each hat style underwent testing four times, twice at each of two different hospitals. Both ORs had high-efficiency air-cleansing ventilation systems, according to the researchers.

          The multidisciplinary research team -- a microbiologist, engineers specializing in ventilation, an industrial air hygienist, and a surgeon -- used their previously developed method involving multiple tests of what they call environmental quality indicators. In one test using a particle counter, they counted tiny airborne particles, such as hair and skin cells, that landed in various parts of the room. They also measured microbial shedding, the bacteria and other micro-organisms collected and grown in Petri dishes placed at the sterile operating field and the instrument table in the back of the room.

            During the mock operations, the bouffant hats and the disposable surgical skullcaps had similar airborne particle counts, the study investigators reported. However, cloth skullcaps, which do not have a porous crown like their disposable counterparts, reportedly outperformed bouffant hats, showing lower particle counts and significantly lower microbial shedding at the sterile field compared with bouffant hats.

        Although Dr. Markel said that reusable skullcaps are "probably best" for minimizing airborne contamination in the OR, their disadvantage is the need to wash them. "Most hospitals don't have facilities to launder them, and surgeons may not launder their skullcaps every day," he said. "There needs to be a way to guarantee that reusable skullcaps are clean." The Chicago-based ACS recommends that cloth skullcaps be changed and cleaned daily.
