An assessment using bedside thoracic ultrasound (TUS) improves diagnostic evaluation and therapeutic management in critically ill patients without undue risk. With changes in diagnosis occurring in 23% of cases and alterations in management in 39% of critically ill patients, TUS can improve length of stay, reduce complications, minimize delays in therapy, and lower hospitalization costs.1 Compared with its cardiac counterpart, attaining proficiency in lung ultrasound (LUS) is easier.2 Intensivists are at risk of forgoing mastering LUS in favor of developing more difficult skills. Proficiency in LUS is essential, as more than half of TUS evaluations are for respiratory complaints and most findings are pulmonary.1
A quick bedside assessment outperforms chest radiographs and available clinical scores in distinguishing pneumonia from atelectasis. The presence of dynamic air bronchograms within the consolidation is 45% sensitive and 99% specific for pneumonia over atelectasis.3 When air bronchograms are static, the presence of flow on color Doppler is 98% sensitive and 68% specific for pneumonia over atelectasis. Similarly, a closer look at the pleural lining shows more than the presence or absence of lung sliding. The presence of fragmentation, irregularity, or thickening of pleural lines provides 100% specificity in discriminating a noncardiogenic interstitial pathology from cardiogenic pulmonary edema.4
LUS is the workhorse and unsung hero of point-of-care ultrasound. In the last year, LUS has shown utility beyond evaluation for pneumothorax, pulmonary edema, and pleural effusion. Its potential impact on diagnosis and management is still growing. We just need to take a closer look.
