摘要
目的探讨16层螺旋CT增强扫描中高压注射器应用的相关问题。方法对采用高压注射器注射造影剂行16层螺旋CT增强扫描的799例患者,进行回顾性分析、总结。结果高压注射器注射造影剂时774例注药顺利;20例造影剂外渗;2例由于长期化疗导致血管广泛受损或血管过细,穿刺不成功;3例误碰按钮导致高压注射器死机,不得不退出药物,卸掉针筒,重新安装。结论掌握高压注射器各环节应用方法,可减轻患者痛苦,获得满意的增强效果。
Objective To discuss the problems of using high pressure injector in the 16 - detector-row CT. Methods Reviewed and analyzed the courses of using high pressure injector in the 16-detector-row CT for 799 patients. Results 774 patients obtained successful infusion, contrast medium hydrops were occurred in 20 patients, 2 patients were infusion failure and 3 patients were redid for misoperation. Conclusion Master the details of operating high pressure injector can alleviate the pain of patients, and then obtain the satisfactory effect.
