This prospective study determined the level of radiation exposure of anaesthetists during interventional radiological procedures performed in the endoscopic retrograde cholangiopancreatography suite and cardiac catheterisation laboratory and compared it with the current safety guidelines. Anaesthetists wore area-specific lithium fluoride thermo-luminescent dosimeter badges at standardised positions. A total of 1344 procedures were performed over a 6-month period. Anaesthetists were involved in 39/645 (6.0%) procedures associated with ionisation radiation in the endoscopic retrograde cholangiopancreatography suite and 86/699 (12.3%) in the cardiac catheterisation laboratory. The mean (SD) duration of endoscopic retrograde cholangiopancreatography was 54.8 (29.1) min compared with 67.9 (42.8) min for cardiac catheterisation suite procedures (p = 0.058). The mean (SD) fluoroscopy time per procedure for endoscopic retrograde cholangiopancreatography was 5.5 (4.1) min compared with 12 (10.9) min in the cardiac catheterisation suite (p < 0.001). The combined net radiation exposure over 6 months was 0.28 mSv for endoscopic retrograde cholangiopancreatography procedures and 2.32 mSv in the cardiac catheterisation suite. The combined exposure was less than the maximum recommended exposure of 20 mSv per year.
这项前瞻性研究确定了介入放射学程序中麻醉师的辐射暴露水平，这些程序在内窥镜逆行胰胆管造影套房和心脏导管插入实验室进行，并将其与当前的安全指南进行了比较。麻醉师在标准位置佩戴特定区域的氟化锂热释光剂量计徽章。在 6 个月的时间里共进行了 1344 次手术。在 645 次内窥镜逆行胰胆管造影术相关程序中，麻醉师参与了 39 次（6.0%）与电离辐射有关的程序，在 699 次心脏导管插入术相关程序中，有 86 次（12.3%）。内窥镜逆行胰胆管造影术的平均（SD）持续时间为 54.8（29.1）分钟，而心脏导管插入术的平均（SD）持续时间为 67.9（42.8）分钟（p = 0.058）。内窥镜逆行胰胆管造影术的平均（SD）每次透视时间为 5.5（4.1）分钟，而心脏导管插入术的平均（SD）每次透视时间为 12（10.9）分钟（p < 0.001）。6 个月的综合净辐射暴露量为内窥镜逆行胰胆管造影术的 0.28 毫希弗，而心脏导管插入术的为 2.32 毫希弗。总的暴露量低于每年 20 毫希弗的最高推荐暴露量。
