The presence of pathogen microorganisms in the operating room remains a significant concern. This study aims to explore the factors influencing the presence of pathogens in the operating room.
We analysed the presence of microorganisms in the operation theatre during total knee and hip replacement procedures for 33 patients performed in the same operation room (OR) over a period of 2 months. Three hundred and ninety-six samples were taken from several areas belonging to the sterile field. We have also analysed behavioural aspects in the OR that could influenced the potential contamination of the sterile field, such as the number of touches of the lamps, the temperature in the OR, the height of the operating table, the number of door openings.
Out of the total of 396 samples, 74 were positive. Most contaminations were with (45.45%). Most pathogens were found on the instrument table at the end of the intervention (27.27%). There is a correlation regarding the fact that at lower heights, the risk of contamination higher than if the table is raised more. We also find correlations between the number of operating room doors opened and the presence of field contamination, as well as between the number of touches of the lamps and the presence of pathogens on sterile fields.
The presence of pathogens in the OR is influenced by the number of lamp touches, the frequency of door openings, and the increased number of people in the room. However, temperature and the height of the operating table do not have a significant impact on the occurrence of pathogens. The most commonly found pathogen in the OR was . At the end of the surgery, the instrument table showed the highest percentage of pathogen presence.

手术室中病原微生物的存在仍然是一个重大问题。本研究旨在探讨影响手术室中病原体存在的因素。
我们分析了在同一手术室（OR）中对33例患者进行全膝关节和髋关节置换手术期间手术室中的微生物存在情况，为期2个月。从属于无菌区域的几个区域采集了396个样本。我们还分析了手术室中可能影响无菌区域潜在污染的行为因素，如灯的触摸次数、手术室温度、手术台高度、门的开启次数。
在总共396个样本中，74个呈阳性。大多数污染是由……引起的（45.45%）。大多数病原体在干预结束时在器械台上被发现（27.27%）。存在这样一种相关性，即高度越低，污染风险高于手术台升高更多时的情况。我们还发现手术室门打开的次数与区域污染的存在之间存在相关性，以及灯的触摸次数与无菌区域病原体的存在之间存在相关性。
手术室中病原体的存在受灯的触摸次数、门的开启频率以及房间内人数增加的影响。然而，温度和手术台高度对病原体的发生没有显著影响。手术室中最常见的病原体是……。手术结束时，器械台显示出病原体存在的百分比最高。
