目的探讨心理干预对64层螺旋CT冠状动脉成像的效果。方法样本为我科室2009年9月-2010年9月期间进行CT冠状动脉造影检查的100例患者,随机分为干预组和对照组。对照组检查前给予一般指导和口服美托洛尔,干预组在检查前给予系统的心理干预和口服美托洛尔,比较两组检查者心率控制速度、呼吸配合训练时间和检查过程心率波动>10bpm的发生率、检查成功率情况。结果干预组检查者心率控制速度及呼吸配合训练时间明显较对照组缩短,检查过程心率波动>10bpm的发生率较对照组低,检查成功率较对照组高,经统计学处理,t=8.91,11.78;χ2=18.97,17.83;P均<0.05,差异具有统计学意义。结论系统的心理干预能明显降低64层螺旋CT冠状动脉检查者控制心率和呼吸配合训练所消耗时间,降低检查过程心率波动幅度,提高检查成功率,使设备、人力资源得到最大程度的发挥。
Objective To investigate the effect of psychological intervention on 64-slice spiral CT coronary angiography. Methods One hundred patients with CT coronary angiography in our department from September 2009 to September 2010 were randomly divided into intervention group and control group. Before the test, the control group was given general guidance and oral metoprolol. The intervention group was given systematic psychological intervention and oral metoprolol before the test. The heart rate control rate, respiratory coordination training time and heart rate fluctuation during the examination were compared between two groups> 10bpm incidence, check the success rate. Results The rate of heart rate control and the training time of breathing cooperation in the intervention group were significantly shorter than those in the control group. The incidence of heart rate fluctuation> 10bpm during the examination was lower than that of the control group. The success rate of examination was higher than that of the control group. After statistical analysis, t = 8.91, 11.78; χ2 = 18.97,17.83; P <0.05, the difference was statistically significant. Conclusions Systemic psychological intervention can significantly reduce the time spent on controlling heart rate and respiratory coordination training by 64-slice spiral CT coronary artery examiners, reduce the amplitude of heart rate fluctuation during examination, and improve the success rate of examinations so that the equipment and human resources can be fully utilized.
