【目的】探讨CT血管成像（CTA）及CT灌注成像（CTP）扫描检查患儿时对比剂外渗原因及干预措施。【方法】回顾性分析2012年1月至2014年12月在本院行C T A或C T P扫描检查的112例患儿的临床资料，记录对比剂的给药剂量和速度，观察对比剂外渗及不良反应发生情况，分析其原因并探讨其对策。【结果】CTA、CTP扫描检查扫描1次成功者82例（73．2％）；30例扫描失败，其中4例患儿配合不佳（3．6％），9例（8．0％）在注射对比剂过程中发生不良反应，17例发生造影剂的外渗（15．2％）。112例中有12例（10．7％）发生了不良反应，其中3例为变应性反应，经抗过敏和对症治疗后好转，9例为生理反应，经休息并大量饮水后好转。17例发生造影剂的外渗（15．2％，17／112），经止血、冰敷等处理后均好转。【结论】儿童行CTA或CTP扫描检查易发生对比外渗及不良反应，在护理中需严格控制对比剂注射的给药速度和剂量。

[Objective] To explore the causes and interventions of adverse reactions and contrast extravasa‐tion during computed tomography angiography or perfusion (CTA/CTP) scan in children .[Methods] A total of 112 children were examined by CTA/CTP and the speed and dose of contrast injection recorded .The causes and interventions of adverse reactions and contrast extravasation were analyzed retrospectively .[Results] The speeds of contrast injection were 0 .8~3 mL/s during CTA and 2~3 mL/s during CTP .And the dose of con‐trast was 0 .8 ml/kg .Adverse reactions occurred in 12 children (10 .7% ,12/112) ,including allergic responses improving after anti‐allergic and symptomatic measures ( n=3) and physiological responses responding well to rest and drinking ( n=9) .And contrast extravasation in 17 children (15 .2% ,17/112) improved after hemo‐stasis and ice compression .[Conclusion] Adverse reactions and contrast extravasation occur frequently during CTA/CTP scan .And it is necessary to control the speed and dose of contrast during nursing .
