Abstract

PURPOSE

To develop a practical method of estimating the volume of pleural effusions with sonography.

MATERIALS AND METHODS

Fifty-one patients underwent sonography of the pleural space while supine. Sonographic results and results of lateral decubitus radiography were compared with actual effusion volumes. The maximum thickness of the pleural fluid layer was measured with both modalities, while actual effusion volume was determined by means of complete drainage.

RESULTS

Sonographic measurements correlated statistically significantly better with actual effusion volume (r = .80) than did radiographic measurements (r = .58) (P < or = .05). With sonographic measurement, an effusion width of 20 mm had a mean volume of 380 mL +/- 130 (standard deviation), while one of 40 mm had a mean volume of 1,000 mL +/- 330. Prediction error with sonographic measurement (mean, 224 mL) was statistically significantly less (P < or = .002) than that with radiographic measurement (mean, 465 mL).

CONCLUSION

In quantification of pleural effusions, the sonographic measurement method presented is preferable to radiographic measurement.

摘要

目的

开发一种利用超声检查估计胸腔积液量的实用方法。

材料与方法

51例患者在仰卧位时接受胸腔超声检查。将超声检查结果和侧卧后前位X线摄影结果与实际胸腔积液量进行比较。两种检查方式均测量胸腔积液层的最大厚度，而实际胸腔积液量通过完全引流来确定。

结果

超声测量与实际胸腔积液量的统计学相关性（r = 0.80）显著优于X线摄影测量（r = 0.58）（P≤0.05）。采用超声测量时，积液宽度为20 mm的平均积液量为380 mL±130（标准差），而40 mm的平均积液量为1000 mL±330。超声测量的预测误差（平均224 mL）在统计学上显著小于X线摄影测量（平均465 mL）（P≤0.002）。
