Measures for the prevention of postsurgical infections include issuing special scrubs for the operating room (OR) and prohibiting walking out of the OR complex wearing these scrubs. The aim of this study was to provide further data on bacterial contamination of surgical scrubs.
Specimens were collected at the entrance to the OR from surgical scrubs worn by surgeons. Participants completed a questionnaire regarding the times, places, and activities in which they were involved during the time interval they were wearing the scrubs.
Among the 133 surgeons who participated, the median colony-forming unit (CFU) count was higher (39 CFU/plate) for their scrubs than for clean scrubs worn by the control group (3 CFU/plate; n = 11; P < .001), but there was no significant difference between the study and control groups in the rate of carriage of pathogenic bacteria (13% and 9%, respectively). The majority of the bacteria isolated were considered commensals. Fifty-five (41%) of the surgeons stated that before sampling they took part in medical activities, and 45 (34%) participated in non-medical activities. Practicing these activities was associated with a higher number of CFUs compared to not being involved in such activities (P < .05).
Our data show that, even in less than optimal situations when scrubs are worn outside the OR, surgical scrubs are contaminated with a low bacterial load and only a small number of pathogenic bacteria.
预防术后感染的措施包括为手术室（OR）发放专用刷手服，并禁止穿着这些刷手服从 OR 区域走出。本研究旨在提供有关手术刷手服细菌污染的进一步数据。
在 OR 入口处收集外科医生穿着的手术刷手服标本。参与者完成了一份问卷，内容涉及他们在穿着刷手服期间的时间、地点和活动。
在 133 名参与的外科医生中，他们穿着的刷手服的菌落形成单位（CFU）计数中位数（39 CFU/平板）高于对照组（11 名，穿清洁刷手服）（3 CFU/平板；P <.001），但研究组和对照组之间携带致病菌的比率没有显著差异（分别为 13%和 9%）。分离出的大多数细菌被认为是共生菌。55 名（41%）外科医生表示，在采样前他们参加了医疗活动，45 名（34%）参加了非医疗活动。与不参加此类活动相比，进行这些活动与 CFU 数量增加相关（P <.05）。
我们的数据表明，即使在刷手服从 OR 区域外穿着的情况下不太理想，手术刷手服也会被低细菌负荷和少量致病菌污染。
