The aim of this work is to present a methodology and some initial results for a pilot program on radiation protection (RP) in pediatric interventional cardiology under the auspices of the International Atomic Energy Agency. The starting point of the program was a workshop involving several pediatric cardiologists leading this specialty in 11 Latin American countries. The workshop included a pilot RP training course and additional sessions during which the objectives of the program and the methodology to collect and process data on patient and staff radiation doses were discussed. Special attention was dedicated to agree on a common quality control (QC) protocol for the x-ray and imaging systems used in the different catheterization laboratories. The preliminary data showed that only 64% of the cardiologists used their personal dosimeters regularly and that only 36% were aware of their personal dose values. The data on pediatric interventional activity were collected from 10 centers from nine different countries. A total of 2,429 procedures (50% diagnostic and 50% therapeutic) were carried out during 2009 in these centers. Patient dose data were available in only a few centers and were not analyzed on a regular basis in any of the catheterization laboratories involved. Plans were developed for a basic QC protocol of the x-ray systems and construction of a Latin American database on pediatric cardiology with patient and staff dose values with the idea in mind of obtaining distributions of these dose values before promoting several optimization strategies.
本工作旨在介绍在国际原子能机构的支持下，开展儿科介入心脏病学辐射防护（RP）试点计划的方法和初步结果。该计划的起点是一个涉及 11 个拉丁美洲国家的几位儿科心脏病专家的研讨会。该研讨会包括一个试点 RP 培训课程和其他几次会议，期间讨论了该计划的目标以及收集和处理患者和工作人员辐射剂量数据的方法。特别关注的是为不同导管室使用的 X 射线和成像系统商定一个共同的质量控制（QC）协议。初步数据表明，只有 64%的心脏病专家定期使用个人剂量计，只有 36%的人了解自己的个人剂量值。儿科介入活动的数据是从 9 个不同国家的 10 个中心收集的。这些中心在 2009 年共进行了 2429 例（50%为诊断性，50%为治疗性）操作。只有少数几个中心提供了患者剂量数据，而且没有任何一个参与的导管室定期对其进行分析。已经制定了 X 射线系统基本 QC 协议的计划，并构建了一个拉丁美洲儿科心脏病学数据库，其中包含患者和工作人员的剂量值，目的是在推广几种优化策略之前获得这些剂量值的分布情况。
