Intraoperative sampling of airborne particulates is rarely performed in the OR environment because of technical difficulties associated with sampling methodologies and because of the common belief that airborne contamination is infrequently associated with surgical site infections (SSIs). In this study, investigators recovered non-viable (i.e., lint) and viable (i.e., microorganisms) particulates during vascular surgery using a personal cascade impactor sampling device. The predominant nonviable particulates recovered during intraoperative sampling were wood pulp fibers from disposable gowns and drapes. Several potential nosocomial pathogens (e.g., Staphylococcus aureus, Staphylococcus epidermidis) and other drug-resistant isolates frequently were recovered from an area adjacent to the surgical field. The widespread presence of airborne particulates during surgery suggests that further studies are warranted to assess the role these particles may play in the development of SSIs or in dissemination of nosocomial pathogens within the OR and hospital environment.
由于与采样方法相关的技术困难，以及人们普遍认为空气传播污染与手术部位感染（SSIs）的关联不常见，因此在手术室环境中很少进行空气传播微粒的术中采样。在本研究中，研究人员使用个人级联撞击采样装置在血管手术期间回收了无生命的（即棉绒）和有生命的（即微生物）微粒。术中采样期间回收的主要无生命微粒是一次性手术衣和手术单中的木浆纤维。从手术区域附近经常回收几种潜在的医院病原体（如金黄色葡萄球菌、表皮葡萄球菌）和其他耐药菌株。手术期间空气传播微粒的广泛存在表明，有必要进一步研究，以评估这些微粒在手术部位感染的发生或医院病原体在手术室和医院环境中的传播中可能发挥的作用。
