CT增强扫描检查中碘对比剂渗漏因素及相关性分析

摘要

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.%目的 探讨CT增强扫描检查中碘对比剂渗漏的相关因素及预防措施.方法 对2015年CT增强扫描检查中发生渗漏的46例患者的临床资料进行回顾性分析.结果 不同性别患者的渗漏率差异有统计学意义(P＜0.05);渗漏率与患者年龄有关(P＜0.01);渗漏率随注射速率增加有升高趋势(P＜0.05),渗漏率与对比剂浓度有关(P＜0.05);渗漏率没有随注射剂量增加而升高的趋势(P=0.675);渗漏率与注射护士从事该项工作年限长短有关(P＜0.01).结论 女性患者的渗漏率较男性高,年龄越大、对比剂浓度越大、注射速率越快、注射护士从事该项工作年限越短,渗漏率越大.
