肺脏超声在AECOPD气胸患者临床诊断中的价值

Values of Clinical Diagnosis in AECOPD with Pneumothorax by Lung Ultrasound

目的探讨肺脏超声在慢性阻塞性肺疾病急性加重期(Acute Exacerbation Chronic Obstructive Pulmonary Disease,AECOPD)气胸患者临床诊断中的价值。方法比较分析我院接诊的52例AECOPD气胸患者同时接受胸部CT检查、肺脏超声检查和X线检查的结果,分析肺脏超声与X线诊断AECOPD气胸的敏感性、特异性及准确率。结果 3种检查方式在气胸严重度评估方面图像结果基本一致;胸部CT、肺脏超声及X线诊断AECOPD合并轻度气胸、中重度气胸及液气胸比例基本一致,差异无统计学意义(P>0.05);肺脏超声漏诊率明显低于X线,差异有统计学意义(P<0.05);肺脏超声诊断AECOPD合并气胸敏感性、特异性、准确率优于X线,尤其在诊断轻度气胸中差异明显(P<0.05)。结论肺脏超声诊断AECOPD气胸操作简单,准确度好,值得临床推荐。

Objective To explore the values of clinical diagnosis in AECOPD with pneumothorax by lung ultrasound. Methods The test results of chest CT, lung ultrasound and X ray for 52 cases of AECOPD with pneumothorax were observed. The sensibility, specifcity and precision of lung ultrasound and X ray were analyzed. Results The image analysis results in different severity of pneumothorax assessment for three ways of checking were the same. There was no signifcant difference on the rate of AECOPD with mild pneumothorax, moderate-severe pneumothorax, hydropneumothorax by chest CT, lung ultrasound and X ray （P〉0.05）. The rate of missed diagnosis for lung ultrasound were lower than X ray （P〈0.05）. The sensibility, specifcity and precision for lung ultrasound were better than X ray, especially in mild pneumothorax checking （P〈0.05）. Conclusion The lung ultrasound is handled easily with well accuracy. It is worthwhile to be used.
