【摘要】：目的调查某医院介入放射工作人员(以下简称"介入人员")受照剂量。方法采用判断抽样法,以某医院的10名介入人员为研究对象,在其进行9种常见的介入放射操作时,采用热释光剂量计测量其左右手虎口处、左右足部、左眼及双眼中间的辐射剂量。记录不同介入放射类型操作过程中介入设备的工作条件和患者的剂量面积乘积(DAP),分析介入人员受照剂量和患者DAP值的关系。结果不同类型的介入操作中,冠状动脉(以下简称"冠脉")支架植入术时管电流最大,且曝光持续时间最长(P0.05)。冠脉支架植入术患者的DAP值高于其余8种介入术的患者(P0.05)。冠脉造影术、胆管造影术及冠脉支架植入术介入人员6个监测部位受照剂量均高于四肢血管造影术、起搏器植入术、肾脏介入操作、静脉造影术、肺栓塞及血管成形术者(P0.05)。冠脉造影术和冠脉支架植入术介入人员左手受照剂量分别高于其余5个监测部位(P0.05)。介入人员受照剂量与患者DAP值呈正相关(秩相关系数=0.381,P0.01)。结论几种常见介入术中,个体受照剂量水平最高的是冠脉支架植入术;对单一个体而言,介入术操作者左手受照剂量最大。
[Abstract]:Objective to investigate the radiation dose of interventional radiation workers (hereinafter referred to as interventional personnel) in a hospital. Methods Ten interventional personnel in a hospital were studied by the method of judging sampling. When they were undergoing 9 kinds of common interventional radiations, the left and right hand tiger's mouth, left and right foot were measured by thermoluminescence meter. The dose of radiation in the left eye and in the middle of the eye. The working conditions of interventional equipment and the product of patient dose area during the operation of different types of interventional radiation were recorded. The relationship between the exposure dose of interventional personnel and the DAP value of patients was analyzed by (DAP),. Results among the different types of interventional procedures, the maximum current and the longest exposure duration were observed in coronary artery stent implantation (P 0.05). The DAP value of the patients with coronary stent implantation was higher than that of the other 8 interventional procedures (P0.05). Coronary angiography, cholangiography and coronary stent implantation were higher than those in limb angiography, pacemaker implantation, renal interventional operation and intravenous angiography. Pulmonary embolism and angioplasty (P0.05). The left hand radiation dose of coronary angiography and coronary stent implantation was higher than that of the other 5 monitoring sites (P0.05). There was a positive correlation between the exposure dose of interventional personnel and the DAP value (rank correlation coefficient = 0.381g / P0.01). Conclusion in several common interventional procedures, the highest dose of individual irradiation is coronary stent implantation, and for a single individual, the maximal dose is received by the left hand of the interventional operation operator.
