“…Serial LUS video recordings were obtained using MyLab30, Esaote, Genova, Italy, with a 3-to 11-MHz linear transducer. As previously recommended [25,26], the chest wall was divided into 12 regions. We delineated the anterior and posterior axillary lines as practical landmarks that defined the anterior, lateral, and posterior areas of both lungs (6 regions per side, Figure 1).…”

Objectives. To comprehensively and quantitatively assess the process of lung liquid clearance using the lung ultrasound score. This study is to evaluate the whole healthy lungs of neonates during the first 24 h. Methods. Lung ultrasound was performed in neonates with no respiratory symptoms within 3 h after birth, and scans were then repeated at 6 hours and 24 hours, respectively. The entire chest wall was divided into 12 regions. The lung ultrasound scores of the anterior, posterior, upper, and lower regions and sum of all regions were calculated according to the ultrasound pattern of each region examined. Results. The total lung ultrasound score decreased gradually during the first 24 h, with the total lung ultrasound score at 6 h being significantly lower than that at <3 h (P<0.05). At <3 h, B-lines were more abundant in the posterior chest than in the anterior chest (P<0.001), and more B-lines were observed in the lower chest than in the upper chest (P<0.001). At 6 h and 24 h, there were no significant differences among the regions. Conclusion. Changes in the lung ultrasound score may quantitatively reflect the characteristics of different regions and processes of lung liquid clearance during the first 24 h.

“…Sixty-six neonates were enrolled, and we studied 2376 videos. e time of examinations was 144.5 (102-163) min, 363 (352-381) min, and 26 (25)(26)(27) hours after birth, respectively. B-lines were observed in most neonates (59/66) within 3 h after birth and in 39/66 at 6 h and 30/66 at 24 h after birth.…”

“…Lung ultrasound characteristics were classified into four categories (N, B1, B2, and C), and scored as 0 to 3 points (Fig 4). [27][28][29][30] The worst ultrasound characteristic was considered representative of a particular lung zone and given the corresponding score. 31,32 Scores of the 12 examined zones were summed to calculate the lung ultrasound score (LUS), ranging from 0 to 36.…”

BACKGROUND: Traditional methods for cardiopulmonary assessment of patients with coronavirus disease 2019 (COVID-19) pose risks to both patients and examiners. This necessitates a remote examination of such patients without sacrificing information quality. RESEARCH QUESTION: The goal of this study was to assess the feasibility of a 5G-based robotassisted remote ultrasound system in examining patients with COVID-19 and to establish an examination protocol for telerobotic ultrasound scanning. STUDY DESIGN AND METHODS: Twenty-three patients with COVID-19 were included and divided into two groups. Twelve were nonsevere cases, and 11 were severe cases. All patients underwent a 5G-based robot-assisted remote ultrasound system examination of the lungs and heart following an established protocol. Distribution characteristics and morphology of the lung and surrounding tissue lesions, left ventricular ejection fraction, ventricular area ratio, pericardial effusion, and examination-related complications were recorded. Bilateral lung lesions were evaluated by using a lung ultrasound score. RESULTS: The remote ultrasound system successfully and safely performed cardiopulmonary examinations of all patients. Peripheral lung lesions were clearly evaluated. Severe cases of COVID-19 had significantly more diseased regions (median [interquartile range], 6.0 [2.0-11.0] vs 1.0 [0.0-2.8]) and higher lung ultrasound scores (12.0 [4.0-24.0] vs 2.0 [0.0-4.0]) than nonsevere cases of COVID-19 (both, P < .05). One nonsevere case (8.3%; 95% CI, 1.5-35.4) and three severe cases (27.3%; 95% CI, 9.7-56.6) were complicated by pleural effusions. Four severe cases (36.4%; 95% CI, 15.2-64.6) were complicated by pericardial effusions (vs 0% of nonsevere cases, P < .05). No patients had significant examination-related complications. INTERPRETATION: Use of the 5G-based robot-assisted remote ultrasound system is feasible and effectively obtains ultrasound characteristics for cardiopulmonary assessment of patients with COVID-19. By following established protocols and considering medical history, clinical manifestations, and laboratory markers, this system might help to evaluate the severity of COVID-19 remotely.

“…By means of the same scores, lung ultrasound can detect changes in lung aeration occurring during a spontaneous breathing trial (SBT) and predict the risk of post-extubation failure. 30 To date, the available recommendations on weaning plan for ventilated COVID-19 patients follows standard protocols of the general population. 31 As suggested by current experience COVID-19 patients may require prolonged respiratory support with mechanical ventilation.…”

The role of lung ultrasonography in COVID‐19 disease management

Coronavirus disease 2019 (COVID‐19) has created unprecedented disruption for global healthcare systems. Offices and emergency departments (EDs) were the first responders to the pandemic, followed by medical wards and intensive care unit (ICUs). Worldwide efforts sprouted to coordinate proper response by increasing surge capacity and optimizing diagnosis and containment. Within the complex scenario of the outbreak, the medical community shared scientific research and implemented best‐guess imaging strategies in order to save time and additional staff exposures. Early publications showed agreement between chest computed tomography (CT) and lung sonography: widespread ground‐glass findings resembling acute respiratory distress syndrome (ARDS) on CT of COVID‐19 patients matched lung ultrasound signs and patterns. Well‐established accuracy of bedside sonography for lung conditions and its advantages (such as no ionizing radiation; low‐cost, real‐time bedside imaging; and easier disinfection steps) prompted a wider adoption of lung ultrasound for daily assessment and monitoring of COVID‐19 patients. Growing literature, webinars, online materials, and international networks are promoting lung ultrasound for the same purpose. We propose 11 lung ultrasound roles for different medical settings during the pandemic, starting from the out‐of‐hospital setting, where lung ultrasound has ergonomic and infection control advantages. Then we describe how medical wards and ICUs can safely integrate lung ultrasound into COVID‐19 care pathways. Finally, we present outpatient use of lung ultrasound to aid follow‐up of positive case contacts and of those discharged from the hospital.
