摘要
目的探究规范化呼吸训练应用于多层螺旋CT胸部检查的临床效果。方法选取2014年12月至2015年12月本院影像科接收的200例行胸部16层CT检查的患者作为研究对象,将患者随机均分为观察组与对照组,观察组患者检查前进行规范化呼吸训练,对照组仅在检查过程中随机告知注意事项。对比两组患者检查前准备时间、图像伪影评分以及检查时的心率变化。结果两组患者检查前准备时间相比差异无统计学意义(P〉0.05);观察组心率升高例数显著少于对照组,心率下降例数显著多于对照组(P〈0.05),而心率不变例数相比差异无统计学意义(P〉0.05);观察组中肺区、下肺区和总体的图像伪影评分均显著低于对照组(P〈0.05),而上肺区评分相比差异无统计学意义(P〉0.05)。结论规范化呼吸训练能够有效减少16层CT中的中、下肺区的图像伪影,缓解患者紧张情绪,改善图像质量,同时不会增加检查前的准备时间,具有在临床上推广的价值。
Objective To explore the clinical effect of standardized respiratory training applied in the chest examination of multi-slice spiral CT. Methods 200 patients scheduled for chest CT examination in medical imaging department of our hospital from December 2014 to December 2015 were selected as the object of study, and randomly divided into observation group and control group. Patients in the observation group received standardized respiratory training before the examination, while patients in the control group were randomly informed of the matters need attention during the process of examination. The examination preparation time, image artifact score, the change of heart rate (HR) during the examination of two groups were compared. Results There was no statistically significant difference in the examination preparation time between two groups (P〉0.05). The rate of increased HR in the observation group was significantly lower than that of the control group (P〈0.05), the rate of decreased HR was significantly higher than that of the control group (P〈0.05), there was no statistically significant difference in the rate of unchanged HR between two groups (P〉0.05). Middle lung zone, lower lung zone image artifact scores and the overall image artifact score in the observation group were lower than those of the control group (P〈0.05), there was no statistically significant difference in upper lung zone image artifact score (P〉0.05). Conclusion Standardized respiratory training can effectively reduce the middle and lower lung zone image artifact, ease tension of patients, improve image quality, does not increase the examination preparation time, has the value of popularization in clinic.
