Surgical staff behavior in operating theatres is one of the factors associated with indoor air quality and surgical site infection risk. The aim of this study was to apply an approach including microbiological, particle, and microclimate parameters during two simulated surgical hip arthroplasties to evaluate the influence of staff behavior on indoor air quality. During the first hip arthroplasty, the surgical team behaved correctly, but in the second operation, behavioral recommendations were not respected. Microbiological contamination was evaluated by active and passive methods. The air velocity, humidity, temperature, and CO concentration were also monitored. The highest levels of microbial and particle contamination, as well as the highest variation in the microclimate parameter, were recorded during the surgical operation where the surgical team behaved "incorrectly". Turbulent air flow ventilation systems appeared more efficient than in the past and very low air microbial contamination was reached when behavior was correct. Therefore, adherence to behavioral recommendations in operating theatres is essential to not undermine the effectiveness of the heating, ventilation, and air conditioning systems and employed resources.
手术室医护人员的行为是与室内空气质量和手术部位感染风险相关的因素之一。本研究旨在应用包括微生物学、粒子和微气候参数的方法，在两次模拟髋关节置换手术中评估医护人员行为对室内空气质量的影响。在第一次髋关节置换手术中，手术团队的行为是正确的，但在第二次手术中，没有遵守行为建议。通过主动和被动方法评估微生物污染。还监测了空气速度、湿度、温度和 CO 浓度。在手术团队行为“不正确”的情况下，记录到最高水平的微生物和粒子污染以及微气候参数的最大变化。与过去相比，紊流空气流通系统似乎更有效率，当行为正确时，空气中的微生物污染非常低。因此，在手术室中遵守行为建议对于不破坏加热、通风和空调系统以及所使用资源的有效性至关重要。
