【摘要】：背景超声评估膈肌功能的方法在国内仍未广泛开展,我们的研究拟对正常人群通过超声测量膈肌厚度以及膈肌移动度来评估膈肌功能,以期得出正常范围值,为临床评估患者膈肌功能提供方法学参考。方法选取150位志愿者(75名男性,75名女性)为研究对象,根据肺通气功能检查纳入受检者,M型二维超声测量不同呼吸时相(平静呼吸、深吸气)受检者膈肌的厚度和移动度,得出正常人膈肌厚度和移动度的正常范围值;分析性别、年龄、身高、体重以及BMI对膈肌厚度、移动度的影响,并结合最大吸气压,提出超声评估膈肌功能的临床价值。结果我们收集了138位正常人(男性61人,女性77人)的完整参考数据,发现正常人平静呼吸时膈肌厚度为0.19±0.04cm,膈肌移动度为1.4±0.4c m;用力吸气后,厚度分数为1.7 1±0.5 8,膈肌移动度为5.1±1.2c m。结果还显示膈肌厚度、膈肌移动度存在显著性别差异。我们还发现受检者身高、体重、BMI影响膈肌厚度,它们与膈肌厚度呈显著正相关;而受检者身高、体重、年龄影响膈肌移动度,膈肌移动度与受检者年龄呈负相关(r=-0.243,P0.05)。此外,结果还表明膈肌厚度分数、移动度均与最大吸气压存在显著正相关(r=0.484,r=0.489;P0.05),提示膈肌形态学参数与膈肌收缩功能有关。结论我们的研究主要提供了超声测量的正常人膈肌形态的正常参考范围值;性别、年龄、身高、体重会影响膈肌形态。另外,膈肌形态与膈肌收缩力有关,证实超声测量膈肌厚度、移动度能够评估膈肌功能,为临床提供有价值的方法学。
[Abstract]:Background ultrasound assessment of extensive method of diaphragm function in China has not yet, our study of normal population as measured by ultrasound, the thickness of the diaphragm and diaphragmatic excursion to assess diaphragmatic function, in order to obtain the normal range, to provide a methodological reference for the clinical evaluation of patients with diaphragmatic function. Methods 150 volunteers (75 women and 75 men), as the research object, according to the pulmonary function test in subjects, measuring two-dimensional ultrasound M in different respiratory phases (quiet breathing, deep breathing) thickness and mobility of the subjects of the diaphragm, the normal range of diaphragm thickness and mobility values; gender analysis age, height, weight, and BMI on the thickness of the diaphragm, the impact of mobile degree, combined with the maximum inspiratory pressure, the clinical value of ultrasound assessment of diaphragm function proposed. Results we collected 138 normal people (61 men, 77 women) full participation Test data, found that normal quiet breathing diaphragm thickness was 0.19 + 0.04cm, diaphragmatic excursion was 1.4 + 0.4C m; after sniffing, thickness fraction was 1.71 + 0.58, diaphragmatic excursion was 5.1 + 1.2C M. results also showed that the thickness of the diaphragm, the diaphragm movement there are significant gender differences. They also found that the subjects of height, weight, BMI effect of diaphragm thickness, and the thickness of the diaphragm was positively correlated; while the subjects of height, weight, age of diaphragmatic excursion, diaphragmatic excursion and patient age was negatively correlated (r=-0.243, P0.05). In addition, it is also shown the diaphragm thickness fraction, mobility and maximal inspiratory pressure had a significant positive correlation (r=0.484, r=0.489; P0.05), suggesting that diaphragmatic morphological parameters associated with contractile function of diaphragmatic muscle. Conclusion our study mainly provides reference ultrasound measurement of the normal diaphragm shape range value; gender, age, height body. In addition, diaphragm morphology is related to diaphragm contractility. It is confirmed that diaphragm thickness and mobility can be used to evaluate diaphragm function and provide valuable clinical methods for clinic.
