摘要

背景和目的：从事透视引导内窥镜检查的医疗保健专业人员在职业上暴露于电离辐射。我们评估了MEDO V-Fix®患者固定装置是否可以减少这种暴露。方法：使用护具内佩带的个人剂量计对护士和医生进行每月有效剂量和晶状体等效剂量的测量。比较器械引入前7个月和引入后10个月的数据。此外，还进行了剂量减少的成本效益分析（CBA）。结果：两种职业的月有效剂量均下降，但均无统计学意义。相比之下，护士的平均透镜等效剂量从每次手术35.0 μSv急剧下降到6.5 μSv (P)。结论：MEDO V-Fix显著降低了内窥镜护士的职业辐射暴露，从CBA的角度来看是值得投资的。

Impact of a patient fixation device on healthcare worker radiation doses in fluoroscopy-assisted endoscopy.

Background and aims: Healthcare professionals involved in fluoroscopy-guided endoscopy are occupationally exposed to ionizing radiation. We evaluated whether a patient-immobilization device, MEDO V-Fix®, reduces this exposure.

Methods: Monthly effective and lens equivalent dose were measured for nurses and doctors using personal dosemeters worn inside protective gear. Data from 7 months before and 10 months after device introduction were compared. Additionally a cost-benefit analysis (CBA) of dose reduction was performed.

Results: Monthly effective doses fell in both professions, but neither decline reached statistical significance. By contrast, nurses' mean lens-equivalent dose dropped sharply from 35.0 to 6.5 μSv per procedure (P < 0.01), whereas the reduction in doctors was not significant. In the CBA, assuming a 5-y service life, the benefit-to-cost ratio ranged 1.02-2.72, indicating economic merit.

Conclusions: The MEDO V-Fix significantly reduces the occupational radiation exposure of endoscopy nurses and is a worthwhile investment from a CBA perspective.

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
