目标.辐射散射防护罩帘的设计目的是减少经股动脉导管插入术期间操作者的辐射剂量。我们试图调查专门为放射状入路设计的各种屏蔽帘对操作者辐射暴露的影响。背景由于患者舒适度的提高和出血并发症的减少，用于心导管插入术的桡动脉通路已经增加。人们担心患者和操作员的辐射暴露会增加。方法.在心导管实验室用RadCal剂量计测量模拟操作员的辐射剂量。模拟患者是一个97.5 kg裂变产物体模。研究了三种无铅铺巾设计。铺巾放置在右手腕近端，并向中间延伸至体模躯干。模拟诊断性冠状动脉造影包括6分钟的透视时间和32秒的电影血管造影时间，4个标准成角视图（每个8秒），均为15帧/秒。采用Bonferroni校正的ANOVA进行统计分析。结果与对照组相比，所有铺巾设计均显著降低了操作者的辐射暴露（P < 0.0001）。辐射暴露的最大降低（72%）是L形设计。结论.在模拟心导管插入过程中，专用的放射状屏蔽帘可将操作员的辐射暴露降低高达72%。
Objectives. Radiation scatter protection shield drapes have been designed with the goal of decreasing radiation dose to the operators during transfemoral catheterization. We sought to investigate the impact on operator radiation exposure of various shielding drapes specifically designed for the radial approach. Background. Radial access for cardiac catheterization has increased due to improved patient comfort and decreased bleeding complications. There are concerns for increased radiation exposure to patients and operators. Methods. Radiation doses to a simulated operator were measured with a RadCal Dosimeter in the cardiac catheterization laboratory. The mock patient was a 97.5 kg fission product phantom. Three lead-free drape designs were studied. The drapes were placed just proximal to the right wrist and extended medially to phantom's trunk. Simulated diagnostic coronary angiography included 6 minutes of fluoroscopy time and 32 seconds of cineangiography time at 4 standard angulated views (8 s each), both 15 frames/s. ANOVA with Bonferroni correction was used for statistical analysis. Results. All drape designs led to substantial reductions in operator radiation exposure compared to control (P < 0.0001). The greatest decrease in radiation exposure (72%) was with the L-shaped design. Conclusions. Dedicated radial shielding drapes decrease radiation exposure to the operator by up to 72% during simulated cardiac catheterization.
