实时辐射数据对介入手术人员辐射暴露的影响

Effect of real-time radiation data on radiation exposure of interventional surgical personnel

目的了解医务人员辐射暴露情况,为介入手术医务人员,提供实时辐射剂量监测数据。方法选择2019年9月—2022年3月在介入手术室参与心脏手术的医务人员96人次作为研究对象。按时间进展进行分组,干预组43人次,对照组53人次。干预组研究对象在手术过程中,提供实时剂量监测数据;对照组研究对象按常规流程进行手术。比较2组研究对象的平均术中辐射剂量率。结果干预组研究对象的中位辐射剂量率为88.80μSv/h,对照组研究对象的中位辐射剂量率为188.40μSv/h。干预组较对照组研究对象,辐射剂量率明显降低,差异有统计学意义(U=637.000,P=0.000)。结论为介入手术医务人员提供实时剂量监测数据,可有效降低医务人员职业辐射暴露,改善医务人员的职业辐射防护。

Objective To analyze the radiation exposure of medical personnel,and to provide real-time radiation dose monitoring data for medical personnel in interventional surgeries.Methods A total of 96 person-times who participated in cardiac surgeries in interventional operating rooms from September 2019 to March 2022 were selected as subjects.The subjects were divided into two groups according to the time progress,with 43 person-times in intervention group and 53 persontimes in control group.The subjects in the intervention group were provided with radiation dose monitoring data during surgeries,while the subjects in the control group performed surgeries with routine procedures.The average intraoperative radiation dose rates of the two groups were compared.Results The median radiation dose rate was significantly lower in the intervention group than in the control group(88.80μSv/h vs 188.40μSv/h,U=637.000,P=0.000).Conclusion Providing real-time radiation dose monitoring data for medical personnel in interventional surgeries can effectively reduce their occupational radiation exposure and improve their occupational radiation protection.
