摘　　要：目的分析CT增强扫描后发生对比剂渗漏的影响因素。方法回顾性收集2019年1月至2021年5月于江苏省人民医院(以下简称“我院”)接受CT增强扫描后发生对比剂渗漏的51例患者的资料,纳入发生组;收集同期我院接受CT增强扫描后未发生对比剂渗漏的51例患者资料,纳入未发生组。记录并分析两组基线资料,统计两组扫描部位、注射部位及对比剂注射速率,采用logistic回归模型分析CT增强扫描后发生对比剂渗漏的影响因素。结果发生组合并高血压占比、合并糖尿病占比、合并恶性肿瘤占比、注射前臂小静脉占比及对比剂注射速率均高于未发生组,差异有统计学意义(P<0.05)。多因素分析结果显示,合并高血压、合并糖尿病、合并恶性肿瘤、注射前臂小静脉、注射速率快是CT增强扫描后发生对比剂渗漏的独立危险因素(OR>1,P<0.05)。结论CT增扫描后发生对比剂渗漏可能受多种因素的影响,临床应根据患者具体情况严格控制注射速率,对存在上述风险的患者应密切观察对比剂渗漏情况,及时处理,保证CT增强扫描的质量及患者生命安全。Objective To analyze the influencing factors of contrast medium leakage after CT enhanced scan.Methods Data of 51 patients with contrast medium leakage after CT enhanced scan in Jiangsu Provincial People’s Hospital(hereinafter referred to as“our hospital”)from January 2019 to May 2021 were retrospectively collected and included in the occurrence group.Data of 51 patients without contrast medium leakage after CT enhanced scan in our hospital during the same period were collected and included in the non-occurrence group.Baseline data of the two groups were recorded and analyzed,scanning sites,injection sites,and contrast medium injection rates of the two groups were statistically analyzed,and logistic regression model was used to analyze the influencing factors of contrast medium leakage after CT enhanced scan.Results The proportion of patients with combined hypertension or diabetes mellitus or malignant tumor,forearm vena injection,and contrast medium injection rate were higher than those in the non-occurrence group,and the differences were statistically significant(P<0.05).Multivariate analysis showed that hypertension,diabetes mellitus,malignant tumor,forearm vena injection and rapid injection rate were independent risk factors for contrast medium leakage after CT enhanced scan(OR>1,P<0.05).Conclusion The contrast medium leakage after CT enhanced scan may be affected by a variety of factors,and the injection rate should be strictly controlled according to the specific situation of patients.For patients with the above risks,the contrast medium leakage should be closely observed and treated in time to ensure the quality of CT enhanced scan and the safety of patients’lives.
