摘要
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。
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 （67.9l ± 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）μSv, 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）lxSv and （0.26 ± 1.01）txSv, 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. （J Intervent Radiol, 2012, 21：514-515）
