The occupational exposure to methylmethacrylate (MMA) vapor during percutaneous vertebroplasty was determined. During five vertebroplasty procedures, air-sampling pumps were attached to medical personnel. MMA vapor levels in the samples were then quantified using gas chromatography. The samples collected yielded MMA vapor levels of less than five parts per million (ppm). The MMA vapor concentrations measured were well below the recommended maximum exposure of 100 ppm over the course of an 8-hour workday.
测定了经皮椎体成形术期间甲基丙烯酸甲酯(MMA)蒸气的职业暴露情况。在五例椎体成形术过程中,将空气采样泵连接到医务人员身上。然后使用气相色谱法定量测定样品中的MMA蒸气水平。所采集的样品中MMA蒸气水平低于百万分之五(ppm)。在8小时工作日期间测得的MMA蒸气浓度远低于建议的最大暴露限值100 ppm。
