[摘要] 目的 探討分析精细化护理干预在冠状动脉CT成像检查患者中的应用效果。 方法 选择2014年3月～2016年3月四川大学华西医院放射科采用德国的Difinition FLASH，sinmens双源CT行冠状动脉CT成像患者158例，采用随机数字表法将其分为干预组80例和对照组78例，对照组给予常规检查流程，干预组给予精细化护理干预，比较两组图像质量、焦虑自评量表（SAS）评分、心率控制时间及呼吸配合训练时间、心率波动幅度>10 bpm发生率。 结果 干预组患者扫描图像质量明显优于对照组，差异有统计学意义（P < 0.05）；两组患者干预前SAS评分比较，差异无统计学意义（P > 0.05）。干预后干预组患者SAS评分较干预前显著降低（P < 0.05），而对照组干预前后SAS评分比较，差异无统计学意义（P > 0.05）。干预后干预组患者SAS评分显著低于对照组（P < 0.05）。干预组患者心率控制时间以及呼吸配合训练时间均明显短于对照组（P < 0.05），心率波动幅度>10 bpm的发生率显著低于对照组（P < 0.05）。 结论 在冠状动脉CT成像患者中运用精细化护理干预，能够有助于患者心率的平稳，减轻患者的心理焦虑情绪，从而提高成像质量，有助于临床诊断，值得推广运用。

[Abstract] Objective To investigate the effect of fine nursing intervention in patients with coronary artery CT imaging examination. Methods From March 2014 to March 2016， 158 patients who recieved coronary CT imaging by Difinition FLASH，sinmens CT angiographyin department of Radiology， West China Hospital， Sichuan University were selected， they were randomly divided into the intervention group （80 cases） and control group （78 cases） according to random number table. The control group was given to conventional nursing scheme， while the intervention group was given to intensive nursing based on the control group. The image quality， SAS score， heart rate control breathing time and cooperating with the incidence of training time， fluctuation of heart rate >10 bpm were compared. Results The quality of the images in the intervention group was significantly better than that of the control group， with statistically significant difference （P < 0.05）. Before intervention， the SAS scores in two groups were not significant difference （P > 0.05）； after intervention， the SAS score in the intervention group was significantly lower than that before intervention （P < 0.05）， while SAS score in the control group before and after intervention had no significant difference （P > 0.05）； after intervention， the SAS score in intervention group was significantly lower than that in the control group （P < 0.05）. The heart rate control time and breathing training time of the intervention group were significantly shorter than those of the control group （P < 0.05）， the incidence of heart rate fluctuation in >10 bpm of the intervention group was significantly lower than that of the control group （P < 0.05）. Conclusion Using intensive nursing intervention in patients with CT imaging of the coronary arteries， can reduce the patients psychological anxiety in patients with heart rate and stable， improve the quality of imaging， which is helpful to clinical diagnosis. It is worthy of clinical application

随着目前影像技术的不断发展和进步，多层螺旋CT在临床工作中广泛运用，其中双源CT诊断冠状动脉病变的特异性、敏感性可达到90%以上，目前已经成为冠状动脉病变无创性检查的首选方法[1-3]。在冠状动脉CT成像中，其图像伪影的产生主要包括心率变化、呼吸运动、造影剂浓度等因素，因此采取有效的干预方法控制患者的呼吸运动，降低心率对于检查尤为重要，可有效减少伪影的产生并提高诊断的准确率[4-5]。本研究探讨分析精细化护理干预在冠状动脉CT成像检查患者中的应用效果，现将结果报道如下：
