Background Advances in imaging techniques have led to increased utilization of imaging devices in catheterization laboratories. Invasive surgical procedures for cardiac disorders have been largely replaced by fluoroscopic cardiac catheterization. With this increase, concerns and risks associated with exposure to ionizing radiation among interventional cardiologists are growing. This study aims to measure and compare the occupational doses to the eye lens and thyroid of pediatric interventional cardiologists during different procedures in the catheterization laboratory and its significance. Methodology In this study, cardiologists wore bandanas with attached dosimeters to measure the absorbed doses to the eyes and thyroid gland. The dosimeters were collected for reading. The procedure types were also collected. In addition, the total fluoroscopy time and tube voltage of the biplane machine were measured. SPSS version 23 (IBM Corp., Armonk, NY, USA) was used to analyze the data. The characteristics of the study sample were described using simple counts and percentages, whereas means and standard deviations were used for continuous variables. Statistical significance was set at p-values <0.05. Results A total of 93 procedures were evaluated. The mean absorbed doses for all 93 procedures in both eyes and thyroid were 0.09 mGy and 0.08 mGy, respectively. A significant difference was found between the left and right eye measurements (p = 0.034), with higher doses administered to the left eye. However, no significant difference was observed between the right and left thyroid doses (p = 0.281). Significant correlations were found between the eye and thyroid doses and the procedure type (p = 0.02 and p = 0.009, respectively). Conclusions A significant amount of radiation was measured in the measurements of both organs. In addition, radiation dose measurements varied between different types of procedures. Our current results indicate the importance and necessity of applying the radiation protection concept of dose optimization.
背景 成像技术的进步导致了导管实验室中成像设备的使用增加。心脏疾病的侵入性外科手术在很大程度上已被荧光镜心脏导管插入术所取代。随着这种增加，介入心脏病专家暴露于电离辐射的相关担忧和风险也在增加。本研究旨在测量和比较儿科介入心脏病专家在导管实验室不同手术过程中眼晶状体和甲状腺的职业剂量及其意义。
方法 在本研究中，心脏病专家佩戴附有剂量计的头巾以测量眼睛和甲状腺的吸收剂量。收集剂量计进行读数。还收集了手术类型。此外，测量了双平面机器的总透视时间和管电压。使用SPSS 23版（美国纽约州阿蒙克市IBM公司）分析数据。研究样本的特征用简单计数和百分比描述，而连续变量用均值和标准差描述。统计学显著性设定为p值<0.05。
结果 共评估了93例手术。93例手术中双眼和甲状腺的平均吸收剂量分别为0.09 mGy和0.08 mGy。左眼和右眼测量值之间存在显著差异（p = 0.034），左眼接受的剂量更高。然而，左右甲状腺剂量之间未观察到显著差异（p = 0.281）。眼睛和甲状腺剂量与手术类型之间存在显著相关性（分别为p = 0.02和p = 0.009）。
结论 在两个器官的测量中都检测到了大量辐射。此外，不同类型手术的辐射剂量测量结果不同。我们目前的结果表明了应用剂量优化辐射防护概念的重要性和必要性。
