简要总结
The objective of this study is to determine whether the Air Barrier System device reduces airborne particulate and airborne colony forming units present at a surgery site.
详细描述
The Air Barrier System is a device that uses localized clean air flow to shield a surgery site from ambient airborne contamination. This study examines the hypothesis that the Air Barrier System can reduce the presence of airborne colony-forming units (e.g. bacteria colonies) and particulate at the surgery site.

结局指标
主要结局
Surgery Site CFU Density
时间窗: Ten minute intervals throughout surgery
Colony forming unit counts were collected from the air within 5 cm of the surgical wound using a bioaerosol "slit" sampling device. Air was drawn through a sterile PVC tubing located at the incision and impacted upon media (TSA 5% sheep's blood) plates located in the sampling device. The plates were exchanged every 10 minutes throughout the procedure. Values are presented as CFU/cubic meter.
次要结局
