综合性放射防护措施在介入治疗防护中的应用

目的探讨综合性放射防护措施在介入治疗防护中的应用价值。方法在84例介入手术治疗中联合应用床下铅橡胶帘、铅玻璃防护屏、铅防护服、铅围脖、铅眼镜及距离等对介入操作人员进行综合性防护。利用FJ-2000个人剂量仪监测X射线辐射剂量,并对相关数据进行统计分析。结果床下铅橡胶帘防护效率为93.4%;铅玻璃防护屏防护效率为93.5%;铅防护服防护效率为88.4%这些放射防护器材前后X线辐射剂量差异均具有统计学意义(P<0.01)。距球管1 m处X线衰减量为58.6%,距球管3 m处的X线衰减量为86.4%。1 m与2 m之间,2 m与3 m之间的辐射剂量差异均具有统计学意义(P<0.01)。结论综合性防护措施在介入操作中可有效降低X射线辐射、减少对介入操作人员身体危害。

The clinical application of comprehensive radiation protection measures in interventional radiology

Objective To discuss the clinical application of comprehensive radiation protection measures in interventional radiology.Methods By a combination use of bed lead rubber curtain,moveable lead glass shield,protective clothing,lead collar,lead glasses and exposure distance,interventional procedures were performed in 84 patients.The X-ray radiation dose of the operators was monitored by FJ- 2000.The results were statistically analyzed.Results The radiation doses estimated before and after the use of lead rubber curtains,lead glass shield,and lead protective clothing were(67.91±73.45)μSv vs. (4.47±10.37)μSv,(56.46±41.23)μSv vs.(3.68±6.46)μSv and(5.2±8.81)μSv vs.(0.61±1.36) |xSv,respectively,and the protective efficiency were 93.4%,93.5%and 88.4%,respectively.The differences were statistically significant(P < 0.01).The radiation doses at the spots 1 m,2 m,and 3 m from the tube were(1.91±2.12)μSv,(0.79±1.92)μSv and(0.26±1.01)μSv,respectively.The attenuations of radiation dose at the spots 1 m and 3 m from the tube were 58.6%and 86.4%,respectively. The differences in radiation dose between the distance 1 m and 2 m,as well as between the distance 2 m and 3 m,were statistically significant(P < 0.01).Conclusion The use of comprehensive protective measures can effectively reduce the radiation dose to the operators attending the interventional procedures.
