Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that correlate with excessive risk.
The radiation exposure of all anesthesiology residents and the attending of Shiraz University of Medical Sciences during a 3-month period (from June to August 2016) was measured using a film badge with monthly readings. Physicians were divided into two groups: group 1 (the ones assigned to ORs with radiation exposure), and group 2 (the ones assigned to ORs with no or minimal radiation exposure).
A total number of 10744 procedures were performed in 3 major university hospitals including 353 cases of pediatric angiography, 251 cases of percutaneous nephrolithotomy, 43 cases of chronic pain palliation and 672 cases of orthopedic surgeries with C-arm application. In all 3 months, there were statistically significant differences in the amount of radiation exposure between the two groups.
Anesthesiologists working in the cardiac catheterization laboratory, pain treatment service, orthopedic and urologic ORs are exposed to statistically significantly higher radiation levels compared to their colleagues in other ORs. The radiation exposure to anesthesiologists can rise to high levels; therefore, they should get proper teaching, shielding and periodic evaluations.
关于麻醉医生的辐射暴露情况，目前可获取的信息较少，伊朗此前也未收集过此类数据。本前瞻性研究旨在确定麻醉医生的辐射暴露量，以评估是否达到危险的辐射暴露水平，并识别与过度风险相关的因素。
在为期3个月的时间（2016年6月至8月）内，使用每月读数的胶片剂量计对设拉子医科大学所有麻醉科住院医师和主治医师的辐射暴露情况进行测量。医生被分为两组：第1组（分配到有辐射暴露的手术室的人员）和第2组（分配到无辐射或辐射极小的手术室的人员）。
3家主要大学医院共进行了10744例手术，包括353例儿科血管造影、251例经皮肾镜取石术、43例慢性疼痛缓解治疗以及672例使用C型臂的骨科手术。在这3个月中，两组之间的辐射暴露量在统计学上存在显著差异。
与其他手术室的同事相比，在心脏导管实验室、疼痛治疗科室、骨科和泌尿外科手术室工作的麻醉医生所接触的辐射水平在统计学上显著更高。麻醉医生的辐射暴露可能会升至高水平；因此，他们应接受适当的培训、防护和定期评估。
