基于CCTA指南探讨不同CT设备行冠脉造影受检者的护理

Nursing care of patients undergoing coronary angiography based on coronary computed tomography angiography guidebooks with different CT devices

目的:探讨不同计算机断层扫描(computed tomography,CT)设备行冠状动脉造影扫描时用不同的扫描方式及给药方法对受检者及护理的影响。方法:基于计算机冠状动脉造影断层扫描(coronary computed tomography angiography,CCTA)指南,将2016年四川大学华西医院西门子二代双源CT机行冠脉血管造影(computed tomography angiography,CTA)的扫描方案定为方案a,其给药方案为根据护士的经验给药,该组受检者为A组;2017年在本院通用电气(GE)公司宽体探测器CT机行冠脉CTA的扫描方案定为方案b,其给药方案根据碘流率给药,该组受检者为B组,观测2组受检者一次性检查成功率、对比剂外渗及不良反应发生率、受检者满意度。结果:GE宽体探测器CT机扫描方式及按碘流率给药方案对受检者配合要求、受检者个体因素、失败率、重复扫描率、对比剂外渗发生率低于西门子二代双源CT扫描方式及按经验给药方案,且受检者满意度更高,两组差异比较具有统计学意义(P<0.05);但对比剂不良反应发生率2组比较无统计学意义(P>0.05)。结论:GE宽体探测器按碘流率给药方案,对受检者配合度要求低,一次性成功率高,能有效提高受检者满意度,简化护理流程,值得临床医技科室推广应用。

Objective:To investigate the effects of different scanning methods and medication with different computed tomography(CT)devices on subjects and their nursing care during coronary angiography. Methods:Based on the coronary computed tomography angiography(CCTA)guidebooks,subjects were divided into the group A and group B. Group A had scanning scheme a of the computed tomography angiography(CTA)using the 2016 Siemens second-generation dual-source CT device in our hospital and medication in accordance with nurses’ experience;group B had scanning scheme b of coronary CTA using 2017 General Electrical(GE)wide detector CT device in our hospital and medication based on iodine flow rate. The one-time examination success rate,contrast agent extravasation,adverse reaction rate,and the satisfaction of the subjects were observed. The difference was considered statistically significant if P<0.05. Results:Requirements for subjects’ cooperation,subjects’ individual factors,failure rate,rescanning rate and the incidence of contrast agent extravasation in the group B were lower than those in the group A;satisfaction degree in the group B was higher than that in the group A;all differences had statistical significance(P<0.05). However,the incidence of adverse reactions in two groups had no statistically significant difference(P>0.05). Conclusion:GE wide detector device combined with the iodine flow rate has low requirement for subjects’ cooperation and high one-time success rate,which can effectively improve the patients’ satisfaction degree and simplify the nursing process,worthy of promotion and application in clinical medical laboratory.
