摘要： 目的探讨电子计算机断层扫描（CT）增强碘对比剂急性不良反应发生及影响因素分析。方法选取天津市肿瘤医院空港医院2020年10月—2023年10月收治的100例行CT增强出现碘对比剂急性不良反应的患者进行回顾性分析,将其分为观察组,另选取同期在我院行CT增强检查未发生不良反应的100例患者作为对照组。分析观察组患者碘对比剂急性不良反应情况,对比两组患者临床资料及碘对比剂注射情况,以急性不良反应作为因变量（发生急性不良反应=1,未发生急性不良反应=0）纳入Logistic回归模型,分析CT增强碘对比剂急性不良反应发生的独立影响因素。结果 100例发生碘对比剂急性不良反应的患者中轻度65例（65.00%）,中度34例（34.00%）,重度1例（1.00%）;观察组与对照组性别、年龄、体质指数（BMI）、高血压史、糖尿病史、心功能不全史、甲状腺功能亢进史、冠状动脉粥样硬化性心脏病史、碘对比剂使用史、食物过敏史对比差异无统计学意义（P>0.05）,观察组与对照组哮喘史（9.00% vs 2.00%）、肾功能不全史（13.00% vs 3.00%）、碘对比剂不良反应发生史（21.00 % vs 2.00%）、花粉过敏史（12.00% vs 4.00%）、药物过敏史（26.00% vs 7.00%）及其他过敏史（10.00 % vs 2.00%）,对比差异有统计学意义（χ²=4.710,P=0.030;χ²=6.790,P=0.009;χ²=17.740,P<0.001;χ²=4.350,P=0.037;χ²=13.100,P<0.001;χ²=5.670,P=0.017）;观察组与对照组碘对比剂剂量对比差异无统计学意义（P>0.05）,观察组与对照组碘对比剂注射速度（<3 mL/min为55.00% vs 69.00%;≥3 mL/min为45.00% vs 31.00%）、碘对比剂类型（碘克沙醇为34.00% vs 34.00%,碘佛醇为47.00% vs 30.00%,碘海醇为19.00% vs 36.00%）对比差异有统计学意义（χ²=4.160,P=0.041;χ²=9.010,P=0.011）;肾功能不全史、碘对比剂不良反应发生史、药物过敏史、其他过敏史、碘对比剂注射速度为发生碘对比剂急性不良反应的影响因素（P<0.05）。结论 CT增强碘对比剂急性不良反应多以轻度为主,且以往合并肾功能不全、碘对比剂不良反应发生史、药物过敏史、其他过敏史、碘对比剂注射速度过高可能为碘对比剂不良反应发生的影响因素。

Abstract: Objective To explore the occurrence and influencing factors of acute adverse reactions of iodine contrast agents in enhanced computed tomography（CT）. Methods A retrospective analysis was conducted on 100 patients admitted to our hospital from October 2020 to October 2023 who experienced acute adverse reactions to iodine contrast agents during CT enhancement．They were divided into an observation group and another 100 patients who underwent CT enhancement examination in our hospital during the same period without any adverse reactions were selected as the control group．The acute adverse reactions of iodine contrast agent in the observation group of patients were analyzed,the clinical data and injection of iodine contrast agent between the two groups of patients were compared,and include acute adverse reactions as the dependent variable（occurrence of acute adverse reactions=1,absence of acute adverse reactions=0）was used in the Logistic regression model to analyze the independent influencing factors of acute adverse reactions of CT enhanced iodine contrast agent．Results Among the 100 patients who experienced acute adverse reactions to iodine contrast agents,65 were mild reactions,accounting for 65.00%,34 cases had were moderate reactions,accounting for 34.00%,and one cases had severe reactions,accounting for 1.00%．There was no significant difference between the observation group and the control group in gender,age,body mass index（BMI）,history of hypertension,diabetes,heart dysfunction,hyperthyroidism,coronary heart disease,use of iodine contrast agent,and food allergy（P>0.05）．The history of asthma（9.00% vs 2.00%）,renal insufficiency（13.00% vs 3.00%）,adverse reactions of iodine contrast（21.00 % vs 2.00%）,pollen allergy（12.00% vs 4.00%）,drug allergy（26.00% vs 7.00%）and other allergies（10.00 % vs 2.00%）were significantly different（χ²=4.710,P=0.030;χ²=6.790,P=0.009;χ²=17.740,P<0.001;χ²=4.350,P=0.037;χ²=13.100,P<0.001;χ²=5.670,P=0.017）．There was no significant difference in the dosage of iodine contrast agent between the observation group and the control group（P>0.05）．The injection rate of iodine contrast agent between the observation group and the control group（< 3 mL/min was 55.00% vs 69.00%;≥3 mL/min was 45.00% vs 31.00%）,and the types of iodoxanol （iodoxanol[34.00% vs 34.00%],iodoxanol[47.00% vs 30.00%],iodohexanol[19.00% vs 36.00%]） were significantly different（χ²=4.160,P=0.041;χ²=9.010,P=0.011）．History of renal insufficiency,adverse reactions to iodine contrast agents,drug allergies,other allergies,and injection speed of iodine contrast agents were independent risk factors for the occurrence of acute adverse reactions to iodine contrast agents（P<0.05）．Conclusions Acute adverse reactions to iodinated contrast agents in CT enhancement are mostly mild．Previous history of renal insufficiency,history of adverse reactions to iodinated contrast agents,history of drug allergies,other allergic histories,and high injection speed of iodinated contrast agents may be influencing factors for the occurrence of adverse reactions to iodinated contrast agents．
