In operating theatres the air is mainly contaminated with bacteria shed from the human skin. The emission of bacteria can be prevented by wearing clothing of impervious material, while normal cotton clothing does not decrease the shedding of bacteria. In this study shedding of viable bacteria from 20 test-persons wearing an operating theatre suit, composed of 65% polyester and 35% cotton (Diolen), was investigated in a test-chamber and compared with that when normal clothing was worn. The use of this operating-theatre suit resulted in a significant reduction (50--75%) in the number of bacteria-carrying particles in the air of the test-chamber and in an operating room when everyone present wore this suit. A combination of the suit with knee-high boots showed a further reduction in the dispersal of colony forming units. The dispersion from female subjects wearing an operating-theatre frock was significantly higher than when wearing an operating-theatre suit.
在手术室中，空气主要被人体皮肤脱落的细菌所污染。通过穿着不透水材料制成的衣物可以防止细菌散发，而普通棉质衣物并不能减少细菌的脱落。在本研究中，对20名穿着由65%聚酯和35%棉花（迪奥林）制成的手术室服装的受试人员在测试室内的活菌脱落情况进行了调查，并与穿着普通衣物时的情况进行了比较。当在场的每个人都穿着这种手术室服装时，使用这种手术室服装可使测试室和手术室空气中携带细菌的颗粒数量显著减少（50%-75%）。这种服装与齐膝高的靴子搭配使用，可进一步减少菌落形成单位的扩散。穿着手术室连衣裙的女性受试者的细菌扩散明显高于穿着手术室服装时。
