Abstract
PURPOSE: To compare the diagnostic performance of lung ultrasound (LUS) and bedside chest radiography (CXR) for the detection of various pathologic abnormalities in critically ill patients. METHODS: Forty Critically-ill patients primarily or secondarily presented with respiratory manifestations, scheduled for CT chest were studied with a standard lung ultrasound protocol & Bedside CXR within ٢٤ hours. Four pathologic entities were evaluated: consolidation, acute interstitial syndromes, pneumothorax, and pleural effusion. RESULTS: Eighty hemithoracies were evaluated by the three imaging techniques. The sensitivity, specificity, and diagnostic accuracy of CXR were ٦٢،٨٩ and %٧٣{u٠٦٦ء} for consolidation٥{u٠٦ئ٠} ، ٧٣{u٠٦٦آ}٦ and٦{u٠٦ئ٠} for interstitial syndrome, ٢٥{u٠٦٦آ}١{u٠٦ئ٠}{u٠٦ئ٠}{u٠٦٦آ} and٧٨{u٠٦٦ء} for pneumothorax, and,٤٦{u٠٦٦آ}٩{u٠٦ئ٠} and٧٨{u٠٦٦ء} for pleural effusion, respectively. The corresponding values for lung ultrasound were {u06F1}{u06F0}{u06F0}{u066B}٨١{u٠٦٦آ}٤and ٩٣{u٠٦٦ء} for consolidation, {u06F1}{u06F0}{u06F0}{u066B}٥٨and %٧٨ for interstitial syndrome, {u06F1}{u06F0}{u06F0}{u066B}٨٦ and ٩{u٠٦ئ٠}{u٠٦٦ء} for pneumothorax, and {u06F1}{u06F0}{u06F0}{u066B}٩٧، and ٩٨{u٠٦٦ء} for pleural effusion, respectively. CONCLUSION: LUS has shown a considerably better diagnostic performance than Bedside CXR in diagnosing of common lung pathologic conditions among critically ill patients and may be used as an alternative to CT chest
