The purpose of this study was to assess the patient exposure and staff eye dose levels during implantation procedures for all types of pacemaker therapy devices performed under fluoroscopic guidance and to investigate potential correlation between patients and staff dose levels. The mean eye dose during pacemaker/defibrillator implementation was 12 µSv for the first operator, 8.7 µSv for the second operator/nurse and 0.50 µSv for radiographer. Corresponding values for cardiac resynchronisation therapy procedures were 30, 26 and 2.0 µSv, respectively. Significant (p < 0.01) correlation between the eye dose and the kerma-area product was found for the first operator and radiographers, but not for other staff categories. The study revealed eye dose per procedure and eye dose normalised to patient dose indices for different staff categories and provided an input for radiation protection in electrophysiology procedures.
本研究的目的是评估在荧光透视引导下进行的各类起搏器治疗设备植入手术过程中患者的受照剂量和工作人员的眼部剂量水平，并研究患者和工作人员剂量水平之间的潜在相关性。在起搏器/除颤器植入过程中，主操作医生的平均眼部剂量为12微希沃特，第二操作医生/护士为8.7微希沃特，放射技师为0.50微希沃特。心脏再同步治疗手术的相应数值分别为30、26和2.0微希沃特。主操作医生和放射技师的眼部剂量与比释动能面积乘积之间存在显著相关性（p < 0.01），但其他工作人员类别不存在这种相关性。该研究揭示了不同工作人员类别每次手术的眼部剂量以及按患者剂量指数归一化的眼部剂量，并为电生理手术中的辐射防护提供了参考依据。
