背景：尽管通过超声检查很容易研究膈肌运动，但该程序仍然缺乏规范。这项前瞻性研究的目的是确定 NI 模式超声检查记录的膈肌运动的参考值。方法：对 200 名健康成年受试者（150 名男性，60 名女性）进行了调查。识别后膈两侧，并使用M模式显示解剖结构的运动。检查是在安静呼吸、自主嗅觉和深呼吸时进行的。根据 NI 模式超声图像测量膈肌偏移。此外，还评估了可重复性（观察者之间和观察者内部）。结果：所有受试者在安静呼吸期间成功评估了左右膈肌运动。在自愿嗅觉期间，总是可以在右侧进行测量，而在 210 名志愿者中，有 208 名在左侧进行测量。在深呼吸期间，在具有明显膈肌偏移的受试者中注意到降肺对膈肌的空气遮蔽。因此，在 210 名受试者中，有 1.95 名受试者可以测量到右侧膈肌偏移，而只有 45 名受试者可以测量到左侧膈肌偏移。最后，两个膈肌偏移的正常值是由于男性的偏移量大于女性，因此应考虑性别，在安静呼吸时，女性的下限值接近 0.9 厘米，男性的下限值接近 1.8 厘米，在深呼吸时，女性的下限值为 1.6 厘米，男性的下限值为 4.7 厘米。结论：我们证明，M 型超声检查是一种可重复的评估方法。半膈运动。
Background: Although diaphragmatic motion is readily studied by ultrasonography, the procedure remains poorly codified. The aim of this prospective study was to determine the reference values for diaphragmatic motion as recorded by, NI-mode ultrasonography.Methods: Two hundred ten healthy adult subjects (150 men, 60 women) were investigated. Both sides of the posterior diaphragm were identified, and M-mode was used to display the movement of the anatomical structures. Examinations were performed during quiet breathing, voluntary sniffing, and deep breathing. Diaphragmatic excursions were measured from the NI-mode sonographic images. In addition, the reproducibility, (inter- and intra-observer) was assessed.Results: Right and left diaphragmatic motions were successfully assessed during quiet breathing in all subjects. During voluntary sniffing, the measurement was always possible on the right side, and in 208 of 210 volunteers, (in the left side. During deep breathing, air obscuration of the diaphragm by the descending lung was noted in subjects with marked diaphragmatic excursion. Consequently, right diaphragmatic excursion could be measured in 1.95 of 210 subjects, and left diaphragmatic excursion in only 45 subjects. Finally, normal values of both diaphragmatic excursions were determined. Since the excursions were larger in men than in women, the gender should be taken into account. The lower limit values were close to 0.9 cm for women and I cm for men during quiet breathing, 1.6 cm for women and 1.8 cm for men during voluntary sniffing,and 3.7 cm for won-ken and 4.7 cm for men during deep breathing.Conclusions: We demonstrated that M-mode ultrasonography is a reproducible method for assessing hemidiaphragmatic movement.
