目的:探索呼吸完全不能配合的患者在CT冠状动脉成像检查中新方法,以期获得满意的图像质量。方法:分析58例CT冠状动脉造影检查过程中呼吸不能配合的特殊临床资料,通过技术人员对其进行呼吸训练,并配合捏鼻干预法,比较常规屏气法和捏鼻呼吸干预法基础心率和检查成功率。结果:常规屏气法患者平均基础心率为(77.10±5.56)次/min,捏鼻呼吸干预法患者平均基础心率为(64.04±4.50)次/min,两组数据比较,差异有统计学意义(t=8.68,P<0.05);常规屏气法患者检查成功率为0;捏鼻呼吸干预法患者检查成功率为100%,两组数据比较,差异有统计学意义(x~2=118.000,P<0.05)。结论:捏鼻呼吸干预法配合呼吸训练可提高冠状动脉成像检查的成功率,改善图像质量。
OBJECTIVE: To explore a new method of CT coronary angiography in patients with respiratory incompatibility with a view to obtaining satisfactory image quality. Methods: 58 cases of CT coronary angiography in the process of breathing can not cooperate with the special clinical data, through the training of technicians to their breathing, and with the method of pinching the nose, the traditional breath holding method and pinch nose breathing method to compare the basic heart rate and examination Success rate. Results: The average basal heart rate was (77.10 ± 5.56) times / min in patients with conventional breath hold method and (64.04 ± 4.50) times / min in pinching nasal breathing interventions, the difference was statistically significant (t = 8.68, P <0.05). The success rate of routine breath-hold test was 0, and the successful rate was 100% in sniffing nasal respiratory intervention patients. There was significant difference between the two groups (P < 0.05). Conclusion: Pinch-nose breathing intervention combined with respiratory training can improve the success rate of coronary angiography and improve the image quality.
