Bacterial contamination of floors and other surfaces in the operating suite has been investigated by contact impression plates during the past five years. Colony counts of the floors of operating rooms, cleaned with disinfectant, were 3.3 c.f.u./10 cm2; on the floors of semi-clean and dirty areas, cleaned with detergent, colony counts were 44.8 and 71.4 c.f.u./10 cm2 respectively. The highest colony counts of 487.4 c.f.u./10 cm2 were found in the dressing rooms, the floors of which were covered with carpets, cleaned with a vacuum cleaner. Mean bacterial numbers on surfaces of various equipment in operating rooms, cleaned with disinfectant, were 2.8 c.f.u./10 cm2. Bacterial numbers on surfaces decreased markedly from 253.2 to 11.9 c.f.u./10 cm2 following the use of disinfectant. Bacterial species found from various surfaces were mainly coagulase-negative staphylococci, derived from human beings. In the light of these findings the regular use of disinfectant for cleaning of the floors and other surfaces in operating rooms is advisable.
在过去五年中，通过接触式印模平板对手术室地面及其他表面的细菌污染情况进行了调查。用消毒剂清洁的手术室地面菌落计数为3.3 c.f.u./10 cm²；在使用洗涤剂清洁的半清洁区和脏污区地面，菌落计数分别为44.8和71.4 c.f.u./10 cm²。在更衣室发现的菌落计数最高，为487.4 c.f.u./10 cm²，其地面铺有地毯，使用吸尘器清洁。用消毒剂清洁的手术室各种设备表面的平均细菌数为2.8 c.f.u./10 cm²。使用消毒剂后，表面细菌数从253.2 c.f.u./10 cm²显著降至11.9 c.f.u./10 cm²。从各种表面分离出的细菌种类主要是凝固酶阴性葡萄球菌，来源于人体。鉴于这些发现，建议定期使用消毒剂清洁手术室的地面及其他表面。
