Effect of real-time radiation data on radiation exposure of interventional surgical personnel / 中国辐射卫生

ABSTRACT

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 person-times 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 (88.80 μSv/h vs 188.40 μSv/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.
