Analysis on leakage factors and their correlation of iodine contrast agent in CT enhanced scanning / 重庆医学

ABSTRACT

Objective To explore the related factors of contrast agent leakage in CT enhanced scanning and to find out its preventive measures.Methods The clinical data of 46 patients with iodine leakage in the CT enhanced scanning during 2015 were retrospectively analyzed.Results The leakage rate had statistically significant difference between different patient's genders(P＜0.05).The leakage rate was related to the age of the patients(P＜0.01).The leakage rate showed the increasing trend with the increase of injection rate(P＜0.05).The leakage rate was related to the concentration of the contrast agent(P＜0.05).The leakage rate had no increasing trend with the increase of injection dose(P=0.675).The leakage rate was related to the years of injection nurses engaging this working(P＜0.01).Conclusion The leakage rate of female patients was higher than that of male.The older the patients,the greater the contrast agent concentration,the faster the injection rate and the lower the working years of injection nurses,the greater the leakage rate.
