摘要

背景:超声测量膈肌运动已被应用于临床实践的不同方面。确定膈偏移的参考值对于鉴别膈运动异常是很重要的。本研究旨在通过Mmode超声确定正常人群膈肌运动的正常范围(参考值)。方法:以健康志愿者为研究对象。排除有合并症、骨骼畸形、急性或慢性呼吸系统疾病的患者。采用低频探头进行仰卧位横膈膜超声。采用b模式进行横膈膜识别,m模式记录静呼吸、深呼吸和嗅探时横膈膜收缩幅度。结果:本研究纳入757名健康受试者,其中男性478人(63.14%),女性279人(36.86%),肺量测定正常,既往或当前无呼吸道疾病史。平均年龄为45.17±14.84岁,BMI为29.36±19.68 (kg/m2)。静呼吸、深呼吸和嗅探的平均右半膈偏移分别为2.32±0.54、5.54±1.26和2.90±0.63 cm,静呼吸、深呼吸和嗅探的平均左半膈偏移分别为2.35±0.54、5.30±1.21和2.97±0.56 cm。在所有研究对象中,右膈肌和左膈肌漂移有统计学上的显著差异。安静呼吸时膈肌左右偏移比为(1.009±0.19);最大181%,最小28%。只有19例右左比小于50%(男性5例,女性14例)。男性膈肌偏移高于女性。不同年龄组间膈肌偏移有显著性差异。年龄、性别和BMI对膈肌运动有显著影响。结论:本研究得出的膈肌漂移值可作为临床诊断膈功能障碍的参考值。横膈膜运动受几个因素的影响,包括年龄、性别和体重指数。

Diaphragmatic excursion by ultrasound: reference values for the normal population; a cross-sectional study in Egypt.

Background: Measurement of diaphragmatic motion by ultrasound is being utilized in different aspects of clinical practice. Defining reference values of the diaphragmatic excursion is important to identify those with diaphragmatic motion abnormalities. This study aimed to define the normal range of diaphragmatic motion (reference values) by Mmode ultrasound for the normal population.

Methods: Healthy volunteers were included in this study. Those with comorbidities, skeletal deformity, acute or chronic respiratory illness were excluded. Diaphragmatic ultrasound in the supine position was performed using a lowfrequency probe. The B-mode was applied for diaphragmatic identification, and the M-mode was employed for the recording of the amplitude of diaphragm contraction during quiet breathing, deep breathing and sniffing.

Results: The study included 757 healthy subjects [478 men (63.14%) and 279 women (36.86%)] with normal spirometry and negative history of previous or current respiratory illness. Their mean age and BMI were 45.17 ±14.84 years and 29.36±19.68 (kg/m2). The mean right hemidiaphragmatic excursion was 2.32±0.54, 5.54±1.26 and 2.90±0.63 for quiet breathing, deep breathing and sniffing, respectively, while the left hemidiaphragmatic excursion was 2.35±0.54, 5.30±1.21 and 2.97±0.56 cm for quiet breathing, deep breathing and sniffing, respectively. There was a statistically significant difference between right and left diaphragmatic excursion among all studied subjects. The ratio of right to left diaphragmatic excursion during quiet breathing was (1.009±0.19); maximum 181% and minimum 28%. Only 19 cases showed a right to left ratio of less than 50% (5 men and 14 women). The diaphragmatic excursion was higher in males than females. There was a significant difference in diaphragmatic excursion among age groups. Age, sex and BMI significantly affected the diaphragmatic motion.

Conclusions: Diaphragmatic excursion values presented in this study can be used as reference values to detect diaphragmatic dysfunction in clinical practice. Diaphragmatic motion is affected by several factors including age, sex and body mass index.
