目的分析冠状动脉造影介入手术患者不同部位受到的辐射剂量。方法采用整群随机抽样法,选取广西4家三级甲等医院的60例分别行冠状动脉造影术(CAG)和冠状动脉造影术及支架植入术(PTCA)的患者为研究对象,采用热释光剂量监测方法分别于手术时对患者甲状腺、后胸部、会阴和左上臂4个部位表面受照剂量进行监测。结果 CAG和PTCA患者甲状腺、会阴和左上臂表面受照剂量均低于后胸部(P<0.05);PTCA患者甲状腺、后胸部和左上臂表面受照剂量均高于CAG患者相应部位(P<0.05)。D医院CAG手术患者甲状腺和左上臂表面受照剂量均高于其他3家医院(P<0.05),会阴表面受照剂量均低于其他3家医院(P<0.05)。结论冠状动脉造影介入手术患者的胸部和甲状腺表面受照剂量较高,应采取适当的辐射防护措施以减少患者的表面受照剂量。
Objective To analyze the dose of radiation received in different parts of coronary angiography interventional surgery. Methods A cluster random sampling method was used to select 60 patients who underwent coronary angiography (CAG) and coronary angiography (CAG) and stent implantation (PTCA) respectively in 4 tertiary hospitals in Guangxi. Luminous dose monitoring methods Surgical patients with thyroid, after the chest, perineum and left upper arm 4 parts of the surface dose monitoring. Results The doses of thyroid, perineum and upper left arm in CAG and PTCA patients were lower than those in the posterior thoracic area (P <0.05). The doses of thyroid, thoracic and upper left arm in PTCA patients were higher than those in CAG patients (P <0.05) ). The doses of thyroid and left upper arm in patients undergoing DAG surgery were higher than those in the other three hospitals (P <0.05). The doses of perineal surface were lower than those in the other three hospitals (P <0.05). Conclusion Patients undergoing coronary angiography have a higher dose of radiation on the surface of the chest and thyroid. Appropriate radiation protection measures should be taken to reduce the surface dose of the patients.
