目的:探究M型超声法,B超直接法和B超间接法对慢阻肺患者病情判定的意义。
方法:以FEV1占预计值%=50为分界线,选取高风险COPD患者40例(高风险组与低风险COPD患者40例(低风险组)。记录两组患者的基本信息,肺功能,血气以及三种超声以及X线下膈肌的移动度的数据。利用单因素和多因素分析筛选影响慢阻肺患者病情严重程度的指标,分析三种超声的测量结果和X线下测量的相关性。采用ROC分析方法,评价3种超声测量方法预测COPD严重程度的价值。
结果:M型超声移动度、B超直接法移动度、B超间接法移动度,X线下的移动度是高风险COPD患者的独立影响因素。M型超声移动度,B超直接法移动度,B超间接超移动度与X线移动度呈显著正相关(r1=0.738,r2=0.667,r3=0.634,P<0.05)。M型和X线联合诊断的诊断COPD的AUC最大,为 0.781。B超间接法移动度AUC最小,为0.610。
结论:M型超声移动度,B超直接法和B超间接法均可以用于COPD病情判定,M超和X线联合诊断的效果更佳。 |

Abstract: |
Objective: To explore the significance of M-mode uhrasoud direct measurement method, B ultrasound direct method and B ultrasound indirect method in the diagnosis of COPD patients.
Methods: 40 patients with high risk COPD (high risk group and 40 low risk COPD patients (low risk group) were selected as the dividing line with the FEV1 account of the estimated value of%=50. The basic information of two groups of patients, lung function, blood gas, and the diaphragmatic muscles mobility of the three kinds of ultrasound and X - ray were recorded. Single factor and multiple factors analysis was used to screen indicators that affect the severity of chronic obstructive pulmonary disease (COPD). The correlation between the three ultrasonic measurements and X-ray measurement was analyzed. ROC analysis was used to evaluate the value of 3 kinds of ultrasonic measurement methods to predict the severity of COPD.
Results: The mobility of M—mode uhrasoud direct measurement method, the degree of mobility of B ultrasonic direct method, the degree of mobility of B ultrasonic indirect method, and the degree of mobility under X - ray were the independent factors of high risk COPD patients. M hyper mobility, B ultrasound direct method mobility, B ultrasonic indirect hyper mobility and X ray mobility have significant positive correlation (r1=0.738, r2=0.667, r3=0.634, P<0.05). The M and X - ray combined diagnosis of COPD was the largest AUC in the diagnosis of 0.781. The minimum mobility of AUC was 0.610. The best diagnosis point of M super mobility is 16.795mm. Its sensitivity is 90% and specificity is 40%. The best diagnosis point is 24.32mm, and its sensitivity is 95% and specificity is 47%. Conclusion: M—mode uhrasoud direct measurement method, B-mode ultrasonography and B-mode ultrasound can be used for the diagnosis of chronic obstructive pulmonary disease. The effect of M ultrasound and X-ray combined diagnosis is better, and it is worthy of clinical promotion. |
