Circulation:研究称,介入医生防辐射还要护腿,否则导致DNA损伤

目前介入医生的铅大衣是不护腿的,而近期一项发表于Circulation的英国研究显示,不防护腿会导致急性DNA损伤,而进行防护能避免。

目前介入医生的铅大衣是不护腿的,而近期一项发表于Circulation的英国研究显示,不防护腿会导致急性DNA损伤,而进行防护能避免。

尽管这种急性损伤在术后24小时可修复。不过研究者指出,进一步明确这种DNA损伤与癌症风险之间的关系,或会避免长期低剂量辐射暴露的风险。

研究中,研究者通过对比对腿部防护或不防护,行主动脉腔内修复术的医生血样,发现标记未防护者的循环淋巴细胞中两种DNA损伤标记物明显增加。

目前关于介入医生职业危害的研究不少,2015年美国心血管造影和介入学会就报告,射线暴露导致的最常见并发症为白内障(5.5%),其次是皮肤相关问题(4.8%)以及血液系统疾病和癌症(4.8%)。

除此外还有研究显示,长期暴露射线的心脏介入医生动脉粥样硬化风险也较高。研究者发现,与对照者相比,心脏导管室工作者颈动脉内膜中层厚度明显增加,而且白细胞端粒长度缩短。

为患者服务很重要,为工作追求很重要,还是做好各种防护,因为你在家人心中更重要。

新华社2015年度感动人物提名奖:介入湘军用生命守护生命

“有时是治愈;常常是帮助;总是去安慰。”对于身穿几十斤铅衣为患者做手术的医护人员来说,他们是在用生命守护生命,用自己的健康换取患者的健康,他们为我们带来了正能量。 摘要:湖南省人民医院有一群医生,他们每次手术都必须头戴铅帽,身穿20多斤重的铅衣,脖子上还套上铅圈。即使这样,一台手术下来他们所“吃”的射线相当于普通放射科医生一年的量。为了守护病人的生命与健康,他们承受射线的辐射,奋战在
