In this study, we aimed to evaluate the bacterial contamination of surgical scrub suits worn outside the operating theatre. We randomised 16 anaesthetists on separate occasions into one of 3 groups: restricted to the operating theatre only; theatre and surgical wards; and theatre and departmental office. For each group, sample fabric pieces attached to the chest, waist and hip areas of each suit were removed at 150 min intervals between 08:30 and 16:00 on the day of study, and sent for microbiological assessment. Mean bacterial counts increased significantly over the course of the working day (p = 0.036), and were lower in the chest compared to the hip (p = 0.007) and waist areas (p = 0.016). The mean (SD) bacterial counts, expressed as colony-forming units per cm(2) at 16:00 on the day of study, were 25.2 (43.5) for those restricted to theatre and 18.5 (25.9) and 17.9 (31.0) for those allowed out to visit the ward and office, respectively (p = 0.370). We conclude that visits to ward and office did not significantly increase bacterial contamination of scrub suits.
在这项研究中，我们旨在评估手术刷手服在手术室外的细菌污染情况。我们将 16 名麻醉师随机分成三组，分别在不同的场合进行：仅限于手术室；手术室和外科病房；手术室和科室办公室。对于每组，在研究日的 08:30 至 16:00 之间，每隔 150 分钟从每个刷手服的胸部、腰部和臀部区域取下附着的小块织物样本，并进行微生物评估。在整个工作日中，细菌计数明显增加（p = 0.036），且与腰部（p = 0.016）和臀部（p = 0.007）相比，胸部的细菌计数较低。在研究日 16:00 时，以每平方厘米形成的菌落形成单位（cfu/cm²）表示的平均细菌计数，限制在手术室的为 25.2（43.5），允许去病房和办公室的分别为 18.5（25.9）和 17.9（31.0）（p = 0.370）。我们得出结论，到病房和办公室的访问并未显著增加刷手服的细菌污染。
