64排螺旋CT冠脉成像质量影响因素分析

Influence of the patient’s with coronary angiography by 64-slice spiral CT

目的探讨不同护理干预条件下影响64排螺旋CT冠脉成像质量的因素。方法 138例行CT冠状动脉成像的患者,双盲法随机分为研究组72例和对照组66例,研究组检查前、中进行护理干预,包括心理干预、健康卫生宣教、屏气呼吸训练;对照组按常规操作进行。观测并记录两组患者检查时心理精神状态、心率控制时间、呼吸配合训练时间、扫描过程中不良反应的发生率及冠脉成像的质量。结果研究组检查时焦虑与恐惧、服用药物的人数、心率控制时间及呼吸配合训练时间、检查中不良反应发生率、图像质量1～2级的比率及冠脉成像运动伪影的出现率均低于对照组(P<0.01,P<0.05)。结论严格有效细致的护理干预是64排螺旋CT冠状动脉成像检查成功的重要保障。

Objective To investigate the influence of nursing intervention on the patients with coronary angiography by 64-slice spiral CT and their image quality. Methods 138 patients with coronary angiography by 64-slice spiral CT were double-blind randomly divided into study group （n=72） and the control group（n= 66）. nursing interventions including psychological intervention, health hygiene education, breath-hold breath training was taken in before and during coronary angiography in the study group and conventional operations was applied in control group. Patients psychological mental state,the time of heart rate control and respiration training,incidence of adverse reactions and coronary imaging quality were observed and recorded.Results The number of anxiety,fear and drug PO, adverse reactions in examination, the time of heart rate control and respiration training, ratio of image quality from 1 to 2 and appearance rat of motion artifact were evidently lower in study group than that in control group （P0.01, P 0.05）. Conclusion The strict and effective nursing intervention is an important guarantee of success in patients with coronary angiography by 64-slice spiral CT.
