摘要
目的探讨使用直插型高压注射器进行64层螺旋CT冠状动脉CTA检查的护理要点和经验,以提高检查的成功率和图像质量。方法 98例怀疑冠心病的患者使用直插型高压注射器注射造影剂进行CT冠状动脉CTA检查,根据患者体质量选择高压注射器的注射方案,分析冠状动脉CTA检查的护理过程和图像质量。结果 1例出现过敏而终止检查,97例完成检查;其中因屏气不良导致伪影者3例,出现期前收缩或心律不齐者5例,高压注射器切换不成功2例,均未出现外渗的情况,增强效果均达到诊断要求。结论检查前的护理准备很重要,包括心率控制、呼吸训练、心理疏导;根据患者体质量选择不同的速率增强可以在保证图像质量的前提下,减少对比剂的注射总量和降低对比剂外渗的风险;直插型高压注射器的使用不同于针筒型高压注射器,对比剂和盐水的切换会影响检查过程。
Objective To discuss the key points and the nursing experience of coronary angiography with 64-slice spiral computed tomography applying direct-inserting high pressure injector and to improve success rate of examination and imaging quality. Methods A total of 98 patients suspected coronary heart disease were conducted coronary angiography with 64-slice spiral computed tomography applying direct-inserting high pressure injector. Meanwhile, the injection methods of high pressure injectorwere selected according to the weightof patients.Besides, the nursing process as well asimaging quality of coronary angiography were analyzed during the examination. Results There were 1 patient quitting the examination due to allergic reaction and 97 patients finishing the examination successfully.Adverse breath holding of 3 patients caused image artifacts and a total of 5patients occured premature beat or arrhythmia. In addition, there were 2 patients had high pressure injector shifting failure. However, none of the patients had exosmosis, and the enhancement effect all achieved diagnosis requirement.Conclusions The nursing preparationsof heart rate controlling,respiratory training and psychological counseling are significant before the examination.As the prerequisite of imaging quality, the enhancement of speed according to the diverse weight of patients could reduce the risk of exosmosis and injection amount of contrast agent. Meanwhile, it reveals that the application of direct-inserting high pressure injector differs from needle syringe,because the shifting of contrast agent and saline water influence could affect the procedure of examination.
