摘　　要：目的探讨超声检查在液气胸诊断中的可行性。方法对213例临床待排除气胸且已经或行将实施胸部CT扫描者行同期（311）双盲胸部X线摄片和超声检查，以CT结果作对照标准，对超声、x线胸片的检查结果行前瞻性比较。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％、73．3％、99．8％与98．0％、99．8与98．1％（P〈0．05）。超声与CT诊断气胸的一致性好于x线片（MeNemar检验，P〈0．025）。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 randomized concurrent controlled trial. 213 patients doubted pneumothorax were examined with CT, sonography and conventional radiography. Results In 213 eases, hydropneumothorax diagnosed in 30 hemithoraces of 30 patients by CT,29 hemithoraees by ultrasound and 22 hemithoraces by X-ray. The sensitivity, negative predictive value,accuracy by ultrasound and X-ray were 96. 7% vs 73. 3% ,99. 8% vs 98.0% ,99. 8 vs 98. 1% respectively（ 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 （ MeNemar test P 〈 0. 025 ）. Conclusion If ultrasound is served to detect pneumothorax,it can make up the defects of the methods commonly used currently.
