目的 对介入电生理学中患者和室内人员辐射剂量测定的各个方面进行全面分析。方法和结果在 19 项诊断电生理学研究和 24 项导管消融期间进行测量。消融的比释动面积乘积和暴露时间值分别为 48.7 (6.4-230) Gy cm(2) 和 25.5 (4.4-79.2) min，诊断研究的比释动面积积和暴露时间值分别为 12.5 (4.5-117.2) Gy cm(2) 和 4.5 (1.2-31) min。消融患者有效剂量为 15.2 (2.1-59.6) mSv，诊断程序患者有效剂量为 3.2 (1.3-23.9) mSv。据估计，在 10 000 次手术中，患者面临的辐射风险高达 8 例致命癌症。对于主要操作者来说，每次手术发生致命癌症的风险低于 3 x 10(-6)。护士和技术人员面临的风险非常大。主操作者每次手术的剂量为眼睛 7.1 mu Gy、铅围裙下胸部 0.79 mu Gy、围裙上方胸部 13.68 mu Gy、甲状腺 3.82 mu Gy、左手 17.76 mu Gy、左膝 12.11 mu Gy。在配备现代设备、经验丰富的操作员和标准安全预防措施的导管实验室中进行射频消融对于患者和人员来说都是安全的手术。
Aims To perform a comprehensive analysis of all aspects of patient and in-room personnel radiation dosimetry in interventional electrophysiology.Methods and results Measurements were performed during 19 diagnostic electrophysiology studies and 24 catheter ablations. Kerma-area product and exposure time values were 48.7 (6.4-230) Gy cm(2) and 25.5 (4.4-79.2) min for ablation, and 12.5 (4.5-117.2) Gy cm(2) and 4.5 (1.2-31) min for diagnostic studies, respectively. Patient effective doses were 15.2 (2.1-59.6) mSv for ablation and 3.2 (1.3-23.9) mSv for diagnostic procedures. Radiation risk to the patient was estimated to be up to eight cases of fatal cancer in 10 000 procedures. The risk of development of fatal cancer was less than 3 x 10(-6) per procedure to the primary operator. The risk for the nurse and technician was much tower. The dose per procedure for the primary operator was 7.1 mu Gy at the eyes, 0.79 mu Gy at the chest under the lead apron, 13.68 mu y at the chest over the apron, 3.82 mu Gy at the thyroid, 17.76 mu Gy at the left hand, and 12.11 mu Gy at the left knee.Conclusion As far as radiation exposure is concerned, etectrophysiology studies followed by radiofrequency ablation are safe procedures for both patient and personnel when performed in catheterization laboratories with modern equipment, experienced operators, and standard safety precautions.
