“…Literature suggests that lung ultrasonography (LUS) can have diagnostic accuracy better than CXR and comparable to CT scan in diagnosing lung pathologies (3,(5)(6)(7)(8)(9). Ultrasonography (USG) was conventionally performed by radiologists, but is now gaining popularity amongst intensivists as it can help in early diagnosis and quick therapeutic decision-making because of its easy bedside availability (10,11).…”

“…Ultrasonography (USG) was conventionally performed by radiologists, but is now gaining popularity amongst intensivists as it can help in early diagnosis and quick therapeutic decision-making because of its easy bedside availability (10,11). Most of the studies in the literature have targeted individual lung pathologies (3,6,8,9), but those comprehensively evaluating diagnostic accuracy of point of care LUS in detecting all lung pathologies together in comparison with CXR and CT scan are limited (4).…”

Objective: To evaluate the diagnostic performance of a rapid bedside 6-point lung ultrasonography (LUS) performed by an intensive care unit (ICU) physician for detection of four common pathological conditions of the lung, such as alveolar consolidation, pleural effusion, interstitial syndrome and pneumothorax, in critically ill patients and its comparison with bedside chest X-ray (CXR) and high-resolution computed tomography (CT) scan of the thorax. Volume of pleural effusion measured by LUS and CT thorax was also compared. Methods: This was a cross-sectional, observational study of 90 adult patients with an acute lung injury score of ≥1 admitted to the medical-surgical ICU. They were examined by CXR and 6-point LUS as per BLUE protocol at bedside, followed by CT thorax in the radiology department. Results: The sensitivity of 6-point LUS for detecting alveolar consolidation, pleural effusion, interstitial syndrome and pneumothorax was 76%, 88%, 83% and 89%, respectively, which was remarkably higher than that of CXR. The specificity of LUS was 100% for all pathologies, which was again notably higher than that of CXR except for interstitial syndrome for which it was 88.5%. Measurement of volume of pleural effusion by LUS was comparable and had a strong absolute agreement with CT thorax. Conclusion: 6-Point LUS can be a useful diagnostic tool and is better than CXR in diagnosing respiratory pathologies in critically ill patients. Owing to the comparable diagnostic performance of LUS and CT scan and with increasing evidence in favour of LUS, the requirement of CT thorax can be reduced. Radiation hazards associated with CXR and CT, as well as potentially risky transfer of patients to CT room, can also be minimised.

“…They showed that bedside ultrasound can be used to evaluate H7N9 avian influenza infection in patients with ARDS, providing a strong basis for adjusting the treatment plan for patients. Therefore, LUS could be useful for the timely monitoring of ARDS caused by the H7N9 virus in clinics,[ 23 ] especially in resource-scarce settings or situations such as future respiratory virus outbreaks or pandemics.

Lung ultrasound: Predictor of acute respiratory distress syndrome in intensive care unit patients

Purpose:The purpose of the study was to review and summarize current literature concerning the validation and application of lung ultrasound (LUS) in critically ill patients with acute respiratory distress syndrome (ARDS).Materials and Methods:An extensive literature search was conducted using PubMed, Cochrane Review, Google Scholar, and Ohio State University Link based on the question if LUS should be considered a reliable investigational technique for ARDS diagnosis, treatment, and prognosis in pediatric and adult population.Results:LUS has been successfully validated for facilitating early diagnosis and diagnosis of simultaneous lung conditions, predicting lung recruitment treatment effect, and evaluating the prognosis in ARDS patients. Whether lung US is a useful tool in the prediction of prone position and oxygenation response in patients with ARDS is conflicting.Conclusions:LUS is a noninvasive, radiation-free, cheap, and easy to perform tool for critically ill patients with ARDS and might be a promising technique used in the Intensive Care Unit for ARDS management.

“…However, LUS is unable to distinguish early COVID-19 from other viral pneumonitis such as RSV, H1N1 20 or H7N9. 21 In the coming months, if the pendulum swings away from COVID-19 and towards alternate causes of respiratory failure, a rethink of the diagnostic approach of COVID-19 using LUS will be necessary.…”

Combatting COVID-19: is ultrasound an important piece in the diagnostic puzzle?

The current COVID-19 pandemic is causing diagnostic and risk stratification difficulties in Emergency Departments (ED) worldwide. Molecular tests are not sufficiently sensitive, and results are usually not available in time for decision making in the ED. Chest x-ray (CXR) is a poor diagnostic test for COVID-19, and computed tomography (CT), while sensitive, is impractical as a diagnostic test for all patients. Lung ultrasound (LUS) has an established role in the evaluation of acute respiratory failure and has been used during the COVID-19 outbreak as a decision support tool. LUS shows characteristic changes in viral pneumonitis, and while these changes are not specific for COVID-19, it may be a useful adjunct during the diagnostic process. It is quick to perform and repeat and may be done at the bedside. The authors believe that LUS can help to mitigate uncertainty in undifferentiated patients with respiratory symptoms. This review aims to provide guidance regarding indications for LUS, describe the typical sonographic abnormalities seen in patients with COVID-19 and provide recommendations around the logistics of performing LUS on patients with COVID-19 and managing the infection control risk of the procedure. The risk of anchoring bias during a pandemic and the need to consider alternative pathologies are emphasised throughout this review. LUS may be a useful point-of-care test for emergency care providers during the current COVID-19 pandemic if used within a strict framework that governs education, quality assurance and proctored scanning protocols.
