Fumes emitted from the ultrasonic instrument while removing polymethyl methacrylate cement were analyzed in three separate phases: phase 1, cement removal from bovine femur in the laboratory; phase 2, methyl methacrylate fumes collected at primary cemented total knee arthroplasty; and phase 3, fumes collected at revision hip surgery. These fumes were collected via personal sampling pumps worn by operating room personnel to determine personal levels of exposure. In phase 1 peak levels of methyl methacrylate and butyl methacrylate were obtained. Phase 2 revealed the highest levels of methyl methacrylate to be only 1 part per million or less (well below the National Institute for Occupational Safety and Health recommended exposure limit of 100 parts per million), and in phase 3 there were no detectable levels of toxic substances. Therefore, we feel that the fumes emitted from the use of ultrasound in revision total hip arthroplasty are safe.
阶段1，在实验室从牛股骨上去除骨水泥；阶段2，在初次骨水泥型全膝关节置换术中收集甲基丙烯酸甲酯烟雾；阶段3，在髋关节翻修手术中收集烟雾。这些烟雾通过手术室人员佩戴的个人采样泵收集，以确定个人接触水平。在阶段1获得了甲基丙烯酸甲酯和甲基丙烯酸丁酯的峰值水平。阶段2显示甲基丙烯酸甲酯的最高水平仅为百万分之一或更低（远低于美国国家职业安全与健康研究所建议的百万分之一百的接触限值），并且在阶段3未检测到有毒物质水平。因此，我们认为在髋关节翻修术中使用超声所排放的烟雾是安全的。
