Lung ultrasound is a technique that has rapidly developed in recent years. It is a low-cost, radiation-free, and easy-to-operate tool that can be repeatedly performed at the bedside. Compared to chest X-ray, lung ultrasound has high sensitivity and specificity in the diagnosis of neonatal respiratory distress syndrome, transient tachypnoea of newborns and pneumothorax. Lung ultrasound has been widely used in neonatal intensive care units. However, it has limitations in some other lung diseases and cannot fully substitute for chest X-ray or CT. This review describes these limitations in detail and highlights that if clinical symptoms are not effectively alleviated after medical treatment or the clinical presentation is not compatible with the ultrasound appearances, then chest X-ray or CT scanning should be performed to avoid misdiagnosis and mistreatment.

Review Study

Objective Pneumothorax (PTX) can be diagnosed using lung ultrasonography (LUS) in adult patients, but there are only a few reports of LUS in PTX diagnosis in neonates. The aim of the study was to assess the diagnostic accuracy for PTX. Study Design This was a retrospective review study performed in our neonatal intensive care unit (level III) between June 2015 and June 2018. All eligible patients underwent an LUS scan before undergoing a chest X-ray (CXR), which was considered the reference standard. When a diagnosis of PTX was inconsistent between LUS and CXR, a chest computed tomography (CT) scan or chest drain was considered the gold standard. Results Among 86 infants included in the study, 30 (34.9%) were diagnosed with PTX. In these 30 infants, 35 PTXs were detected by bedside LUS (five bilateral PTXs). Moreover, 11 infants with 14 PTXs were diagnosed only by LUS and were missed by CXR. Out of these 11 infants, 7 underwent a CT scan, whereas the remaining 4 underwent thoracentesis that confirmed PTX diagnosis. Conclusion In neonates with PTX, LUS was more sensitive and specific for the early detection of PTX compared with CXR.

AbstractFluid overload is a common complication of critical illness, associated with increased morbidity and mortality. Pulmonary fluid status is difficult to evaluate clinically and many clinicians utilize chest X-ray (CXR) to identify fluid overload. Adult data have shown lung ultrasound (LUS) to be a more sensitive modality. Our objective was to determine the performance of LUS for detecting fluid overload, with comparison to CXR, in critically ill children. We conducted a systematic review using multiple electronic databases and included studies from inception to November 15, 2020. The sensitivity and specificity of each test were evaluated. Out of 1,209 studies screened, 4 met eligibility criteria. Overall, CXR is reported to have low sensitivity (44–58%) and moderate specificity (52–94%) to detect fluid overload, while LUS is reported to have high sensitivity (90–100%) and specificity (94–100%). Overall, the quality of evidence was moderate, and the gold standard was different in each study. Our systematic review suggests LUS is more sensitive and specific than CXR to identify pulmonary fluid overload in critically ill children. Considering the clinical burden of fluid overload and the relative ease of obtaining LUS, further evaluation of LUS to diagnose volume overload is warranted.

Background: Lung ultrasound (LUS) has a good performance with a high sensitivity and specificity for the diagnosis of pneumonia compared with chest X-ray, and it has been extensively used to assess patients during the COVID-19 pandemic. This study aims to evaluate the potential advantages of the regular use of LUS for the assessment of the severity and prognosis of COVID-19 pneumonia and to propose an adapted protocol with its inclusion in current local validated and published guidelines.Methods: This is a single-center prospective study conducted during the first (April–May 2020) and second (October 2020–January 2021) waves of the SARS-CoV2 pandemic in Switzerland. All adult patients presenting to dedicated test centers with a suspicion of mild-to-moderate COVID-19 pneumonia and not requiring hospitalization at the time of diagnosis were included. Patients with confirmed COVID-19 pneumonia were referred to an ambulatory follow-up unit at our institution for reassessment, with the inclusion of the use of LUS in a random selection. Descriptive statistics were calculated for demographics using percentages, means, and standard deviations according to the distribution of variables.Results: Eighty-eight ambulatory patients with a confirmed COVID-19 pneumonia were included (men = 57 [59%]; mean age, 52.1 ± 13.5 years). Among these, 19 (21%) were hospitalized and none died. Twenty-five lung assessments by ultrasound were performed during the follow-up consultation. All were consistent with the clinical examination and confirmed the clinician's opinion.Conclusion: The use of a standardized pleuro-pulmonary ultrasound protocol for ambulatory patients with COVID-19 could help to reduce the use of chest X-rays and improve overall management at the time of referral and eventual follow-up. However, a specific study including LUS in a systematic approach should be performed to evaluate the outcome of patients according to findings.

Abstract Purpose To compare between lung ultrasound and chest X-ray in diagnosis of different lung pathologies in critically ill patients using lung CT as a gold standard. Methods Comparative prospective randomized single group observational study was conducted in the Critical Care unit (medical and surgical ICU). The study was conducted upon fifty patients (28 females &22 males) with a mean age of 58 years (SD ± 15.55; (19 - 82) presented to Kom Hamadah Hospital during a period of one year starting from July 2018 to July 2019, with acute dyspnea as the primary complaint or developed acute dyspnea and or tachypnea during their ICU stay were evaluated for the presence of pleural effusion, pneumothorax, alveolar-Interstitial Pathology and consolidation by LUS and CXR for detecting the sensitivity and specificity of each modality with CT chest done as a reference in cases of doubt. Results The comparison between Sensitivity and Specificity of US finding was (86.8% for parenchymal disease, 100.0% for pleural diseases) and (100.0% for parenchymal diseases, 94.7% for pleural diseases) respectively while CXR finding was (65.8% for parenchymal diseases, 75.0% for pleural diseases) and (58.3% for parenchymal diseases), (92.1% for pleural diseases) respectively among studied patients. Conclusion Transthoracic ultrasound is valuable for the evaluation of a wide variety of chest diseases, particularly mechanically ventilated patient. The advantages of low cost, bedside availability and no radiation exposure have made ultrasound an indispensable diagnostic tool in ICU. Lung ultrasound is more sensitive than chest x-ray in diagnosis and follow up chest diseases) PNX, alveolar-interstitial syndromes, parenchymal consolidations, and pleural effusion (LUS is an interesting medical method that is complementary to bedside CXR and reduces the need to use a CT scan.

Abstract Background Pneumonia is consistently among the leading causes of morbidity and mortality worldwide. Defined as acute infection of the lung parenchyma, it is caused by a wide variety of microorganisms, including bacteria, viruses, and fungi. However, pneumonia is often misdiagnosed even now. Early and effective antibiotic treatment is important. An adequate treatment is thus reliant on an early diagnosis of pneumonia, yet the diagnosis is not always clear at presentation to the emergency department (ED). In a retrospective chart review of patients admitted with pneumonia, 22% of patients presented some reason for diagnostic uncertainty that could result in delayed antibiotics delivery. Objective The aim of the study was to evaluate the efficacy of LUS in the diagnosis of pneumonia. Methods This is a prospective observational study which was conducted on 36 consecutive patients with suspected pneumonia. All patients were admitted to the Hospital, in the period from May 2019 to January 2020. Results Chest x-ray diagnosed pneumonia in 66.7% of patients, while lung U/S diagnosed pneumonia in 75% of patients. Lung ultrasound was more sensitive and highly specific for diagnosis of pneumonia as sensitivity and specificity of lung ultrasound was 96.3% and 88.9% respectively while for chest xray was 81.5% and 77.8% respectively. Accuracy of lung ultrasound was 94.4% and that of chest x-ray was 80.6% in relation to CT chest the gold standard with accuracy 100%. Superiority of lung US findings over CXR findings could be explained by high sensitivity & specificity of lung US in diagnosing pneumonia in comparison with chest x ray as high resolution CT is a gold standred for the study. Conclusion LUS is a sensitive and highly specific diagnostic tool in pneumonia. Therefore, we hypothesize that Lung US may be considered as the first imaging test inpatients with suspicion of pneumonia. It should be noted, however, that the ability of LUS to detect lung consolidations located in peri-hilar regions is limited. A diagnostic algorithm of pneumonia which includes Lung US should be validated in prospective studies. Monitoring there solution of pneumonia can be another application of Lung US inpatients with pneumonia.

Abstract lung ultrasound (LUS) was used traditionally in the assessment of pleural effusions and masses but LUS has moved towards the imaging of the pulmonary parenchyma, mainly as a point-of-care technique. Objective To assess the agreement between LUS and CXR for the diagnosis of RD in neonates. Methods This prospective cross sectional study was conducted on 100 neonates presents with RD in the first 24 hours of life in the neonatal intensive care unit (NICU) of the Ain Shams University. All enrolled neonates underwent LUS and CXR initially and on day 7. Neonatologists were blind to the LUS diagnosis and the clinical decisions were driven by CXR findings. Lung score was applied to describe lung aeration, interstitial, alveolar, or consolidation patterns for each lung area. Results 125 different diagnoses were reported in 100 patients. The total agreement between LUS and CXR diagnosis was 96% (95% CI 88–98%) with a κ statistic of 0.94 (95% CI 0.86– 1.00). The agreement for RDS, Pneumonia, TTN, MAS, CDH, PE, Pnumothorax and atelectasis were 99%, 96%,98%, 99%,100%,100%,98% and 98% consequently. Conclusion LUS is a safe, low coast, easy to operate and has high agreement with CXR for the diagnosis of RD in neonates in the first week of life.

Infective lung disease is a spectrum of pulmonary disorders with high prevalence in clinical practice. In the last decade, many studies focused on the clinical usefulness of lung ultrasound (LUS) in the management of patients presenting with dyspnea from infective lung disease. We report data on the methodological and standardized use of bedside LUS in the differential diagnosis of patients with acute dyspnea from infective lung diseases. We performed a cross-sectional study in 439 patients (160 women and 279 men, mean age 64.2 ± 11.5 years, age range 23–91 years) with infective lung diseases. A bedside LUS with a convex probe and chest X-ray were performed in all subjects. Chest CT was performed in a subgroup of patients, as clinically needed. We observed a statistically significant difference in the percentage of pleural effusion and pulmonary consolidation assessed by LUS, compared to X-ray (52.7 vs. 20%, respectively, p < 0.05; 93.6 vs. 48.2%, p < 0.001). The majority of the consolidations detected by LUS were mixed, hypo- and hyperechoic, lesions, with air bronchogram in 40% of cases. All findings assessed by LUS were confirmed by chest CT, when performed. We describe the actual role of LUS in the assessment of patients with infective lung disease. It has higher sensitivity compared to chest X-ray in the detection of pleural effusion. Consolidations from infective lung disease have mostly mixed echogenicity by LUS.
