We report catheterization laboratory personnel dose per case during parallel use of two laboratories from different manufacturers. Initially, four working positions were monitored. Review of the data from the first 140 cases showed a wide range of dose per case. Measurements were then limited to diagnostic coronary angiography cases in which a cardiology fellow was the primary operator. On a per case basis, the dose was higher when a fellow was in the laboratory with pulsed progressive fluoroscopy or was in fellowship year one. The increased dose for first year fellows was more related to increased fluoroscopy time than to cine angiography time. This study emphasizes the importance of close supervision of cardiology fellows early in their training to limit dose to patients and personnel, and it underlines the importance of each catheterization laboratory routinely having the actual personnel dose per case measured.
我们报告了在同时使用来自不同制造商的两个实验室期间，每个病例的导管室工作人员剂量。最初，对四个工作岗位进行了监测。对前140例病例的数据回顾显示，每个病例的剂量范围很广。然后将测量限于诊断性冠状动脉造影病例，其中心内科住院医师为主要操作者。在每个病例的基础上，当住院医师在使用脉冲渐进式荧光透视的实验室中或处于第一年住院医师培训阶段时，剂量较高。第一年住院医师剂量增加更多与荧光透视时间增加有关，而非与电影血管造影时间有关。这项研究强调了在培训早期对心内科住院医师进行密切监督以限制对患者和工作人员剂量的重要性，并且强调了每个导管室常规测量每个病例实际工作人员剂量的重要性。
