BACKGROUND: Lung auscultation and bedside chest radiography are routinely used to assess the respiratory condition of ventilated @entity1 with @entity649 ( @entity649 ). Clinical experience suggests that the diagnostic accuracy of these procedures is poor. METHODS: This prospective study of 32 @entity1 with @entity649 and 10 healthy volunteers was performed to compare the diagnostic accuracy of auscultation, bedside chest radiography, and lung ultrasonography with that of thoracic computed tomography. Three pathologic entities were evaluated in 384 lung regions (12 per @entity1 ): @entity1143 , and @entity1986 . RESULTS: Auscultation had a diagnostic accuracy of 61% for @entity1143 , 36% for @entity133 , and 55% for @entity1986 . Bedside chest radiography had a diagnostic accuracy of 47% for @entity1143 , 75% for @entity133 , and 72% for @entity1986 . Lung ultrasonography had a diagnostic accuracy of 93% for @entity1143 , 97% for @entity133 , and 95% for @entity1986 . Lung ultrasonography, in contrast to auscultation and chest radiography, could quantify the extent of @entity651 . Interobserver agreement for the ultrasound findings as assessed by the kappa statistic was satisfactory: 0.74, 0.77, and 0.73 for detection of @entity1986 , @entity133 , and @entity1143 , respectively. CONCLUSIONS: At the bedside, lung ultrasonography is highly sensitive, specific, and reproducible for diagnosing the main lung pathologic entities in @entity1 with @entity649 and can be considered an attractive alternative to bedside chest radiography and thoracic computed tomography.
