摘要: Abstract Maintaining air quality in operating rooms is import to prevent surgical site infections. Surgical smoke a risk factor for infections that can be caused by bacteria or viruses. In this study, situ measurements were conducted understand the characteristics of airborne particles based on particle size, viable bacteria, and microbiome generated during an endoscopic surgery thoracotomy performed same room single day. During thoracotomy, sharp rise was observed concentration (≥0.3 μm, ≥0.5 μm, ≥1.0 μm diameter) at beginning use electrosurgical tools. Furthermore, higher than surgery. Additionally, mean values both significantly exceeded ISO 14644-1 standard. The level exposure found 4–27 times surgery, near table inlet 56 CFU/m3 undetected, respectively. comparison, 533 CFU/m3 11 CFU/m3, respectively, indicating more Based 16S rRNA analysis, top four genera each sample, is, Streptococcus, Acinetobacter, Neisseria, Staphylococcus, human origin.
