CT增强扫描药物应用分析

Analysis of CT enhanced scanning drugs

目的观察CT增强扫描中静脉注射造影剂导致药物渗出的因素，分析其应对措施。方法抽取2016年1月~2017年6月间在建德市第一人民医院行CT增强扫描中出现药物渗出的61例患者为研究对象，通过对本组患者静脉注射造影剂后药物渗出因素予以观察并记录，以此分析应对措施。结果本组患者药物外渗因素主要为：≥12岁者发生率为63.93%（39/61）；注射流速3.0~4.0mL/s发生率为70.49%（42/61）；注射血管中前臂小静脉80.33%（49/61）；渗透压≥300mOsm/kgH2O发生率为83.61%（51/61）。结论CT增强扫描中导致静脉注射造影剂药物渗出的因素呈多样化，需根据患者药物渗出特异性选择针对性措施干预，可有效改善患者肿胀、血瘀、疼痛等临床指征，具有重要实用价值。

Objective To investigate the factors causing exudation of drugs by intravenous contrast medium in CT enhanced scan,and toanalyze the corresponding measures.Methods From January2016to June2017in the First People’s Hospital of Jiande City61cases of drugextravasation enhanced CT scanning in patients as the research object,through the observation of the drug leakage factors to agents in this groupof patients with intravenous contrast and record,in order to find out measures.Results The statistics show,this group of patients with drugextravasation factors:12years of age,the incidence rate was63.93%(39/61)injection velocity;the incidence rate of3.0~4.0ml/s was70.49%(42/61);small vein injection of vascular forearm80.33%(49/61);osmotic pressure,the incidence rate of300mOsm/kgH2O was83.61%(51/61).ConclusionCT scan causes intravenous contrast agent oozing drugs are various,according to the specific selection of patients with drug exudation measures,caneffectively improve the patients clinicalcharacteristics of blood stasis,swelling,pain,and has important practical value.
