Study On The Dose Of Gonadal Radiation In Patients With Different Venous Coronary Sinus Electrodes

Objective:To compare the radiation dose of gonadal gland by placing the coronary sinus mapping electrode through femoral vein and internal jugular vein puncture,so as to provide a theoretical basis for optimizing operation and reducing radiation dose of patients.To record the X ray radiation dose of different types of arrhythmia patients during electrophysiological examination,compare the radiation dose in different types of arrhythmia operation and the factors that influence the radiation of gonad,so as to provide a theoretical basis for radiation protection of patients.The hazard of gonadal radiation in electrophysiologists and patients and the corresponding protective measures are analyzed,so as to maximize the protection and optimize the protection.Methods:(1)From June 1,2017 to December 31,2017,there were selected 121 patients with arrhythmia who received electrophysiological examination and radiofrequency ablation in the Department of Cardiology catheter room of the first hospital of Shanxi Medical University.Patients were randomly selected internal jugular vein and femoral vein puncture placement of coronary sinus electrode,the two groups were recorded in the process of placing the X-ray exposure time,the success rate of placement of coronary sinus vein puncture time,and with the same dose instrument records of patients with gonadal radiation cumulative dose between statistical method and comparison of 2 kinds of puncture X-ray exposure time,operation time,success rate and cumulative dose of gonadal radiation.(2)58 patients selected according to the type of arrhythmia were divided into double way(21 cases),right accessory pathways(6 cases),left accessory pathways(10 cases),atrial fibrillation(21 cases),and then analyze the operative X-ray exposure total time,total operative time,surgical success rate and the total cumulative dose of radiation gonad the use of statistical methods.Results:There was no significant difference in operative time and success rate between the two groups(P > 0.05).The radiation time and dose recorded by femoral vein puncture(1.25±0.44min)、(18.92 + 8.65 m Gy)were significantly lower than those of internal jugular vein puncture(1.6±0.26min)、(46.22 + 8.01 m Gy)(P<0.05).(2)Double Road,right side,left side,AF gonad total radiation dose respectively(71.82 + 12.87 m Gy),(118.21 + 23.53 m Gy)、(92.21 + 11.03 m Gy)、(531 + 63.50 m Gy).The gonadal radiation of the atrial fibrillation group was the largest,which was significantly higher than that of the other five groups(P<0.05),and the amount of double path ray was the smallest.Conclusion:According to the results of the study,we suggest that we should first choose transhepatic venocentesis when placing the coronary sinus mapping electrode,which can not only reduce the radiation damage of gonad in patients,but also be easy for the operator to operate.At present,the awareness of protection in domestic hospitals is still very weak,and no attention is paid to the use,maintenance and standardization of personal dose instruments.Therefore,it is necessary to strengthen the awareness of protection for medical personnel and patients,and to minimize the radiation injury of medical personnel and patients.
