摘　　要：目的探讨解剖M型超声测量双侧膈肌移动度和收缩速度的可行性,为膈肌运动功能障碍的诊断提供依据。方法选取健康成人118例为研究对象,由同一检查者应用解剖M型超声测量平静呼吸时双侧膈肌移动度和吸气时间两次,计算膈肌收缩速度;以第10和第90百分位对应数值确定膈肌运动参数正常参考值范围。应用组内相关系数(ICC)评价检查者自身超声测量参数的可重复性,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:膈肌移动度9~23 mm,吸气时间972~1482 ms,收缩速度0.82~1.87 cm/s,双侧膈肌运动参数比较差异均无统计学意义。解剖M型超声两次测量膈肌移动度和吸气时间的ICC均>0.9;膈肌运动与性别、年龄、吸烟史及BMI均无明显相关。结论解剖M型超声可以准确测量双侧膈肌移动度,且重复性较好,具有临床推广应用价值。Objective To explore the feasibility of measuring the mobility and contraction velocity of bilateral diaphragm by anatomical M-mode ultrasound,and to provide basis for the diagnosis of diaphragm motor dysfunction.Methods A total of 118 healthy adults were selected,the movement and inspiratory time of bilateral diaphragm were measured twice during quiet breathing with anatomical M-mode ultrasound by the same examiner,and the contraction velocity of diaphragm was calculated.The normal reference range of diaphragm movement parameters were determined by the corresponding values of the 10th and 90th percentiles.Intraclass correlation coefficient(ICC)was used to evaluate the repeatability of ultrasound parameters,and the relationship between diaphragm movement and sex,age,smoking history,body mass index(BMI)was analyzed.Results The normal reference range of diaphragm movement parameters:diaphragm mobility was 9~23mm,inspiratory time was 972~1482 ms,contraction velocity was 0.82~1.87 cm/s,there were no significant difference in bilateral diaphragm movement parameters.The ICC of diaphragm mobility and inspiratory time measured by anatomical M-mode ultrasound were more than 0.9.There was no significant correlation among diaphragm movement and sex,age,smoking history and BMI.Conclusion Anatomical M-mode ultrasound can accurately measure the mobility of bilateral diaphragm,and has good repeatability.It can be widely used in clinic for monitoring diaphragm movement.
