In this report, we demonstrate a versatile method for the removal of bone cement fumes from the vicinity of health care workers in a simulated operating room. The mixing of two component bone cement in the perimeter of an operating room releases volatile organic compounds (VOCs). The use of localized negative pressure within proximity of the mixing vessel is expected to reduce the concentration of VOCs dispersed near the airway of operating room personnel. A standard two component bone cement formulation was mixed in the perimeter of a simulated operating room. A median VOC concentration of 19 ppm was detected with a portable VOC detector. When a portable negative pressure unit was stationed near the mixing area at distances of 8 and 36 cm from the mixing vessel, the median VOC rise was reduced by approximately 97% and 83%, respectively, relative to the control. The use of a portable negative pressure unit provides a potential increase in the safety for all staff when working with materials that give off VOCs in the operating room.
在本报告中，我们展示了一种在模拟手术室中从医护人员附近去除骨水泥烟雾的多功能方法。在手术室周边混合双组分骨水泥会释放挥发性有机化合物 (VOC)。在混合容器附近使用局部负压有望降低在手术室人员气道附近分散的 VOC 浓度。在模拟手术室的周边混合了标准的双组分骨水泥配方。使用便携式 VOC 探测器检测到 19ppm 的中值 VOC 浓度。当便携式负压装置停在混合区域附近，距离混合容器 8cm 和 36cm 时，与对照相比，中值 VOC 上升分别降低了约 97%和 83%。使用便携式负压装置可为在手术室使用会释放 VOC 的材料时所有工作人员的安全提供潜在的提升。
