Areas of potential contamination of the surgical wound in the conventional operating rooms include the back table, the unsterile suction receptacle, and the lack of a positive pressure relationship between the operating room and adjacent areas. Use of an impermeable hood with a large mask diminished contamination of the instrument table and the the wound from fallout of bacteria from the surgical team. The level of airborne bacterial comtamination in the operating room can be reduced by limiting the traffic and controlling the activity and the number of operating room personnel. Higher rates of postoperatively wound sepsis were noted in older operating rooms, particularly with difficult procedures and those performed later in the day. Conventional operating rooms should be categorized by the level of room air exchange per hour and the level of airborne bacterial contamination.
传统手术室中手术伤口潜在的污染区域包括后手术台、未消毒的吸引容器，以及手术室与相邻区域之间缺乏正压关系。使用带有大面罩的不透水罩可减少器械台和手术团队细菌沉降对伤口的污染。通过限制人员流动、控制手术室人员的活动和数量，可以降低手术室空气中细菌污染的水平。在较旧的手术室中，术后伤口感染率较高，尤其是在进行复杂手术以及当天晚些时候进行的手术中。传统手术室应根据每小时的房间空气交换水平和空气中细菌污染水平进行分类。
