摘　　要：目的探讨超声在液气胸中应用的可行性。方法对213例临床不能除外气胸并具有同期(3h)胸部CT、X线胸片的患者行盲法超声检查,以CT结果为准,比较X线和超声的液气胸检出情况。结果超声、X线片诊断液气胸的特异性、阳性预测值均为100%,敏感性、阴性预测、准确性则分别为96.7%对73.3%、99.8%对98.0%和99.8对98.1%(P<0.05)。结论超声作为诊断液气胸的手段可弥补X线之不足。Objective To investigate the value of ultrasound diagnosing for hydropneumothorax. Methods In a prospective double-blind concurrent controlled trial. 213patients doubted pneumothorax were examed with CT,sonography and conventional radiography. Results In 213 cases ,hydropneumothorax diagnosed in 30 hemithoraces of 30 patients by CT, 29 hemithoraces by ultrasound and 22 hemithoraces by X-ray. The sensitivity, negative predictive value, accuracy by ultrasound and X-ray were 96.7% with 73.3%, 99.8% with 98.0%, 99.8 with 98.1% in order（P〈0.05）, the specificity and positive predictive value of both ultrasound and X-ray were 100%.Ultrasound surpassed the X-ray In detecting pneumothorax. Conclusion If ultrasound is served to detect pneumothorax ,that can make up the defects of the methods commonly used currently.
