Background

Real-time dosimeters may create a relatively safer environment not only for the patient but also for the physician and the assistant as well. We propose the use of a real-time radiation measurement dosimeter having auditory feedback to reduce radiation exposure.

Methods

Radiation dose rates were measured for 30 fluoroscopy-guided puncturing procedures of femoral arteries in swine. Fifteen puncturing procedures were performed with real-time radiation measurement dosimeter having auditory feedback and other 15 were performed without auditory feedback dosimeter by an interventional cardiologist with 10 years of experience.

Results

The left body side of the operating physician (38%, p < 0.001) and assistant (25%, p < 0.001) was more exposed as compared to the right body side. Radiation dose rate to the left hand, left arm and left leg were reduced from 0.96 ± 0.10 to 0.79 ± 0.12 mSv/h (17% reduction, p < 0.001), from 0.11 ± 0.02 to 0.07 ± 0.01 mSv/h (36% reduction, p < 0.001) and from 0.22 ± 0.06 to 0.15 ± 0.02 mSv/h (31% reduction, p < 0.001) with the use of auditory feedback dosimeter, respectively. The mean fluoroscopic time was reduced from 4.8 ± 0.43 min to 4.2 ± 0.53 min (p < 0.001). The success rate of performing arterial puncturing was 100%.

Conclusions

The use of auditory feedback dosimeter resulted in reduction in effective dose. The sound beep alerted the physician from the danger of exposure, and this approach induced awareness and protective mindset to the operating physician and assistant.

在股动脉穿刺期间使用实时听觉反馈剂量计减少手术医生和助手的放射线暴露:猪模型研究。

背景

实时剂量计不仅可以为患者而且为医师和助手创建相对安全的环境。我们建议使用具有听觉反馈的实时辐射测量剂量计,以减少辐射暴露。

方法

在30部荧光镜引导下的猪股动脉穿刺程序中测量了辐射剂量率。由具有听觉反馈的实时辐射测量剂量计执行15例穿刺程序,由具有10年经验的介入性心脏病专家在不进行听觉反馈剂量计的情况下执行其他15例。

结果

与右侧相比,手术医师的左侧(38%,p  <0.001)和助手(25%,p  <0.001)更暴露。左手,左臂和左腿的辐射剂量率从0.96±0.10降低到0.79±0.12 mSv / h(降低17%,p  <0.001),从0.11±0.02降低到0.07±0.01 mSv / h(36% 使用听觉反馈剂量计分别将其降低(p  <0.001)和从0.22±0.06降低到0.15±0.02 mSv / h(降低31%,p <0.001)。平均透视时间从4.8±0.43分钟减少到4.2±0.53分钟(p  <0.001)。进行动脉穿刺的成功率为100%。

结论

听觉反馈剂量计的使用导致有效剂量的减少。蜂鸣声使医师警惕了暴露的危险,这种方法引起了操作医师和助手的意识和保护意识。
