A novel radiation protection system has recently been shown to shield the primary operator from scatter radiation, but whether it shields other members of the catheterization laboratory team remains unknown.
Radiation exposure data were collected prospectively in 50 coronary angiography cases, in which 25 were completed using standard radiation protection and 25 with a novel system consisting of a series of rigid shields and flexible radiation-resistant drapes. Radiation doses, measured with real-time dosimeters, were compared between the 2 groups.
There were no significant differences between groups with respect to patient or procedural characteristics, including air kerma ( = .97) and dose area product ( = .17). The primary operator received a median head-level radiation dose of 0.0 [0.0, 0.0] μSv with the novel radiation protection system and 2.1 [0.7, 3.3] μSv with standard radiation protection ( < .001). Scrub technologists had a median head-level radiation dose of 0.0 [0.0, 0.0] μSv with the novel radiation protection system and 0.3 [0.1, 0.4] μSv with standard radiation protection ( < .001). The median head-level radiation dose among circulating nurses was 0.0 [0.0, 0.0] μSv with the novel radiation protection system and was 0.1 [0.0, 0.2] μSv with standard radiation protection ( < .001).
Compared to standard radiation protection with lead aprons, use of a novel radiation protection system during coronary angiography was associated with significantly lower head-level radiation doses among all members of the catheterization laboratory team.
最近有研究表明，一种新型辐射防护系统可使主操作人员免受散射辐射，但该系统能否保护心导管插入实验室团队的其他成员尚不清楚。
前瞻性收集50例冠状动脉造影病例的辐射暴露数据，其中25例使用标准辐射防护完成，25例使用由一系列刚性防护屏和柔性抗辐射帘布组成的新型系统完成。用实时剂量仪测量两组的辐射剂量并进行比较。
两组在患者或手术特征方面无显著差异，包括空气比释动能（=0.97）和剂量面积乘积（=0.17）。使用新型辐射防护系统时，主操作人员头部水平的辐射剂量中位数为0.0[0.0，0.0]μSv，使用标准辐射防护时为2.1[0.7，3.3]μSv（<.001）。刷手技师使用新型辐射防护系统时头部水平的辐射剂量中位数为0.0[0.0，0.0]μSv，使用标准辐射防护时为0.3[0.1，0.4]μSv（<.001）。巡回护士使用新型辐射防护系统时头部水平的辐射剂量中位数为0.0[0.0，0.0]μSv，使用标准辐射防护时为0.1[0.0，0.2]μSv（<.001）。
与使用铅围裙的标准辐射防护相比，在冠状动脉造影过程中使用新型辐射防护系统可使心导管插入实验室团队所有成员的头部水平辐射剂量显著降低。
