立体放射防护在介入治疗中的应用

目的:评价立体放射防护方法在介入治疗中的防护效果及其应用价值。方法:174例患者,介入治疗中分别采用床下铅橡胶帘、床边悬挂可活动式铅玻璃防护屏、医用铅防护服、铅防护围脖、铅防护眼镜及增加距离等X射线辐射防护措施,利用RAD60S个人报警剂量仪测量防护材料防护前后的X射线辐射剂量,并进行统计学分析。结果:铅玻璃防护屏、铅防护服、距离的增加可明显减少X射线辐射剂量,有显著性防护意义;X射线辐射剂量与透视和数字减影血管造影时间呈正相关,随着透视和减影造影时间的增加,医务人员和患者所接受的X射线辐射剂量明显增加。结论:立体防护在介入治疗中可有效减少X射线辐射剂量,保护医务人员和患者的身体健康。

Application of Three-dimensional Radiation Protection for Interventional Radiology

Objective:To evaluate the value of three-dimensional radiation protective measures for interventional radiology. Methods:Plumbous drapes below the operation table,pensile lead glass screen,exposure suit,lead scarf,lead-impregnated eye-glasses and distance protection were used for radiation protection.RADOS RAD-60 personal alarm dosimeter was used to detect the dose of X-ray radiation.Results:Plumbous drapes,pensile lead glass screen,exposure suit and distance protection can obviously reduce the dose of X-ray radiation exposure.Conclusion:The three-dimensional radiation protective measures for interventional radiology can reduce obviously the dose of radiation exposure to operators and patients.
