Spine:含铅眼镜可降低脊柱术中C臂所致的眼睛辐射暴露!

2016-03-30 Seven L MedSci原创

脊柱微创手术中常会使用标准透视C臂X线定位,那么就会存在辐射暴露。近期有研究人员通过模拟人,证明三种不同类型的含铅眼镜可显著降低这种情况下的眼睛辐射暴露!研究成果发表在近期的Spine上。

脊柱微创手术中常会使用标准透视CX线定位,那么就会存在辐射暴露。近期有研究人员通过模拟人,证明三种不同类型的含铅眼镜可显著降低这种情况下的眼睛辐射暴露!研究成果发表在近期的Spine上。

该研究包含四组对象,每组15个模拟人。一组为没有戴眼镜的模拟人头,二组为含铅镜片边框不含铅 (WOLS),三组为镜片和边框都含铅(WLS),四组为运动环绕式铅眼睛(sport)

每组的对象都在正位(AP)和横位透视C臂的情况下,暴露20秒,模拟人头与荧光镜成0°、45°和90°。

研究数据显示,与没有眼镜的模拟人相比,三组含铅眼镜组眼睛的辐射暴露均显著减少!

此外,WOLS组和sport组的总眼睛辐射暴露低于WLS (P=0.003P= 0.009)WOLS组的总眼睛辐射暴露减少的比sport组更多,但是不具有统计学意义(91.4% vs. 90.9 %, P =0.6)WLS组只有当体位为90° AP时,暴露量低于sport组;当体位为45° AP时,暴露量低于WOLS组。
