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．

目的 探讨支气管镜灌洗用于儿童重症肺部感染合并肺实变的治疗效果及对CT特征、肺功能的影响。方法 选取2022年5月—2024年5月铜仁市人民医院收治的100例重症肺部感染合并肺实变患儿开展前瞻性研究,应用随机数表法分为对照组和观察组,每组各50例。对照组患儿采取常规治疗,观察组则采取常规治疗加支气管镜灌洗治疗。对比其临床疗效,治疗前后炎症因子、CT特征及肺功能变化。结果 观察组治疗总有效率高于对照组（P<0.05）;治疗后观察组患儿白细胞计数（10.36±2.52）×10⁹/L、白细胞介素-6（20.57±5.05）ng/L、C反应蛋白（13.12±2.64）mg/L、降钙素原（101.62±12.16）pg/L均低于对照组白细胞计数（13.25±3.32）×10⁹/L、白细胞介素-6（31.69±4.11）ng/L、C反应蛋白（16.16±4.44）mg/L、降钙素原（113.46±18.11）pg/L（P<0.05）;治疗后两组患儿胸腔积液、支气管壁增厚、空气支气管征、肺部实变、磨玻璃影等相关CT影像特征占比下降,且观察组低于对照组（P<0.05）;治疗后两组患儿呼气流量峰值水平均升高,观察组（90.67±18.45）L/s高于对照组（81.27±17.69）L/s,用力肺活量水平均更高,观察组（3.33±0.68）L高于对照组（2.68±0.25）L（P<0.05）。结论 针对儿童重症肺部感染合并肺实变,在常规治疗基础上增加支气管镜灌洗可提升临床疗效,减轻机体炎症反应,改善胸部CT各种表现及肺功能。

Objective To explore the therapeutic effects of bronchoalveolar lavage in children with severe pulmonary infection complicated by lung consolidation and its impact on CT features and pulmonary function．Methods A prospective study was conducted on 100 children with severe pulmonary infection complicated with pulmonary consolidation in a hospital from May 2022 to May 2024．They were randomly divided into observation group and control group using a random number table method,50 cases in each group．The control group of children received routine treatment,and the observation group received conventional treatment plus bronchoalveolar lavage．Clinical efficacy,inflammatory factors,CT features,and alterations in pulmonary function before and after therapy were compared．Results The total effective rate of the observation group was higher than that of the control group（P<0.05）．After treatment,the white blood cell count（10.36±2.52）×10⁹/L,interleukin-6（20.57±5.05）ng/L,C-reactive protein（13.12±2.64）mg/L,and procalcitonin（101.62±12.16）pg/L in the observation group were all lower than those in the control group（13.25±3.32）×10⁹/L,interleukin-6（31.69±4.11）ng/L,C-reactive protein（16.16±4.44）mg/L,and procalcitonin（113.46±18.11）pg/L（P<0.05）．After treatment,the proportion of CT imaging features such as pleural effusion,bronchial wall thickening,air bronchogram sign,lung consolidation,ground glass opacities,decreased in both groups of children,and the observation group was lower than the control group（P<0.05）．After treatment,the peak levels of expiratory flow in both groups of children increased,with the observation group（90.67±18.45）L/s higher than the control group（81.27±17.69）L/s．The forced vital capacity levels were also higher,with the observation group（3.33±0.68）L higher than the control group（2.68±0.25）L（P<0.05）．Conclusions Adding bronchoalveolar lavage to routine treatment for children with severe pulmonary infection complicated with pulmonary consolidation can improve their clinical efficacy,alleviate inflammatory reactions,and improve various chest CT manifestations and lung function．
