To evaluate the radiation dose received by staff in spine surgeries, including those who are not considered occupationally exposed workers.
All spinal surgeries performed in the same department during a period of 12 months were evaluated with regard to the exposure of surgeons, scrub nurses, and auxiliary personnel working in the operating room to radiation from C-arm fluoroscopy. Radiation was measured by 15 film badge dosimeters placed on the professionals' lapels, gloves, and room standardized sites. The films were analyzed in the dosimetry laboratory by collections per period.
During the 12 months, 81 spinal surgeries were performed by the same team, with surgical times ranging from 1 to 6 hours. The total radiation dose ranged from 0.16 mSv to 2.29 mSv depending on the dosimetry site. The most exposed site was the wrist of the main surgeon.
The results showed that in the spinal surgeries in our setting, the radiation doses are low and within legal limits. Nevertheless, constant training of professionals is essential for radiation protection of medical staff and patients.
评估脊柱手术中工作人员所接受的辐射剂量，包括那些不被视为职业暴露人员的工作人员。
对同一科室在12个月期间进行的所有脊柱手术，评估手术医生、洗手护士和手术室辅助人员在C形臂荧光透视下所接受的辐射情况。通过将15个胶片剂量仪分别放置在专业人员的翻领、手套及手术室标准化位置来测量辐射量。胶片由剂量测定实验室按时间段进行收集分析。
在这12个月期间，同一团队共进行了81例脊柱手术，手术时间从1小时至6小时不等。根据剂量测定部位不同，总辐射剂量在0.16毫希沃特至2.29毫希沃特之间。暴露程度最高的部位是主刀医生的手腕。
结果表明，在我们医院的脊柱手术中，辐射剂量较低且在法定限值范围内。尽管如此，持续对专业人员进行培训对于医护人员和患者的辐射防护至关重要。
