Continuous exposure to low-level scattered radiation to staff performing cardiac angiography and intervention is of concern. A novel shielding solution (NSS) (Rampart IC M1128) has the potential to provide greater shielding for staff present at the table-side. This study aimed to investigate the effectiveness of the NSS compared with a traditional shielding solution (TSS) in a randomized controlled trial that enrolled 100 patients who underwent cardiac angiography and/or intervention which were randomized to the NSS or TSS. Baseline patient characteristics and radiation dose data were collected. Staff who were scrubbed at the table-side wore 5 real-time dosimeters on the head, collar, waist, ankle, and under the apron. The median primary operator radiation dose was significantly lower (p <0.001) for all dosimeter locations with the NSS when compared with the TSS, being reduced by 86%, 80.0%, 100%, and 50.0% for the head, collar, waist, and leg respectively. Median under-apron dose was 0.0 µSv for both NSS and TSS. Median second operator dose was reduced by 100%, 100%, and 100% for the head, collar, and waist respectively (p <0.001). Median NSS and TSS dose at the ankle and under apron was 0.0 µSv. Median scrub nurse dose was reduced by 50% and 100% for the head and collar respectively (p <0.001). Median NSS and TSS dose at the waist, ankle, and under apron was 0.0 µSv. In conclusion, the NSS tested in this study demonstrates a significant decrease in radiation dose to operators and scrub nurses when compared with traditional radiation protection measures.
连续接触低水平散射辐射对进行心脏血管造影和介入治疗的工作人员构成关注。一种新型屏蔽解决方案（NSS）（Rampart IC M1128）有可能为在手术台旁的工作人员提供更大的屏蔽。本研究旨在通过一项随机对照试验，调查 NSS 与传统屏蔽解决方案（TSS）的效果比较，该试验纳入了 100 例接受心脏血管造影和/或介入治疗的患者，他们被随机分配到 NSS 或 TSS 组。收集基线患者特征和辐射剂量数据。在手术台旁进行擦洗的工作人员在头部、衣领、腰部、脚踝和围裙下佩戴了 5 个实时剂量计。与 TSS 相比，NSS 时所有剂量计位置的主要操作人员的辐射剂量中位数均显著降低（p<0.001），头部、衣领、腰部和腿部的辐射剂量分别降低了 86%、80.0%、100%和 50.0%。NSS 和 TSS 的围裙下剂量中位数均为 0.0µSv。第二位操作人员的剂量中位数分别降低了 100%、100%和 100%，用于头部、衣领和腰部（p<0.001）。NSS 和 TSS 在脚踝和围裙下的剂量中位数分别为 0.0µSv。擦洗护士的剂量中位数分别降低了 50%和 100%，用于头部和衣领（p<0.001）。NSS 和 TSS 在腰部、脚踝和围裙下的剂量中位数均为 0.0µSv。总之，与传统的辐射防护措施相比，本研究中测试的 NSS 可显著降低操作人员和擦洗护士的辐射剂量。
