| 目的 探讨应用解剖M型超声测量双侧膈肌移动度及收缩速度的可行性,以期为膈肌运动功能障碍的诊断提供依据。方法 选取2020年1月至2020年6月健康体检的成年人118名,由同一位检查者前后两次应用解剖M型超声测量平静呼吸时双侧膈肌移动度及吸气时间,并计算膈肌收缩速度；应用组内相关系数来评价检查者自身超声测量参数的可重复性,并分析膈肌运动与性别、年龄、吸烟史、体质量指数(BMI)之间的关系。结果 膈肌运动参数正常参考值范围：移动度(9~23)mm,吸气时间(973~1483)ms,收缩速度(0.82~1.87)cm/s,两侧膈肌运动参数比较,差异无统计学意义；解剖M型超声测量膈肌移动度及吸气时间ICC值均大于0.9。膈肌运动与性别、年龄、吸烟史及BMI均无明显相关性。结论 应用解剖M型超声可以准确获得双侧膈肌移动度,而且重复性较好,克服了传统的M型超声只能获得右侧膈肌移动度的不足,可作为一种安全、无创、可靠的监测膈肌运动的影像学方法在临床推广应用。 |

| ABSTRACT Objective To explore the feasibility of measuring the mobility and contraction velocity of bilateral diaphragm by anatomical M-mode ultrasound, so as to provide basis for the diagnosis of diaphragm motor dysfunction. Methods A total of 118 healthy adults were selected to measure the movement and inspiratory time of bilateral diaphragm during quiet breathing with anatomical M-mode ultrasound by the same examiner, and the contraction velocity of diaphragm was calculated. Intraclass correlation coefficient（ICC) was used to evaluate the repeatability of ultrasound parameters, and to analyze the relationship between diaphragm movement and sex, age, smoking history, body mass index (BMI). Results The normal reference range of diaphragm movement parameters: mobility (9~23) mm, inspiratory time (973~1483) ms, systolic velocity (0.82-1.87) cm/s, there was no significant difference in diaphragm movement parameters; anatomical M-mode ultrasound measured diaphragm mobility and inspiratory time ICC values were more than 0.9. There was no significant correlation between diaphragm movement and sex, age, smoking history and BMI. Conclusions Anatomical M-mode ultrasound can accurately obtain the mobility of bilateral diaphragm, and has good repeatability, which overcomes the deficiency that the traditional M-mode ultrasound can only obtain the mobility of right diaphragm. It can be widely used in clinic as a non-invasive and non-radiation imaging method for monitoring diaphragm movement. |
