Following the innovations and new discoveries of the last 10 years in the field of lung ultrasound (LUS), a multidisciplinary panel of international LUS experts from six countries and from different fields (clinical and technical) reviewed and updated the original international consensus for point‐of‐care LUS, dated 2012. As a result, a total of 20 statements have been produced. Each statement is complemented by guidelines and future developments proposals. The statements are furthermore classified based on their nature as technical (5), clinical (11), educational (3), and safety (1) statements.

New International Guidelines and Consensus on the Use of Lung Ultrasound

Respiratory tract infections (RTIs) are common complaints among patients presenting to the pediatric emergency department. In the diagnostic assessment of children with RTIs, many patients ultimately undergo imaging studies for further evaluation. Point-of-care lung ultrasound (LUS) can be used safely and with a high degree of accuracy in differentiating etiologies of RTIs in pediatric patients. Ultrasonographical features such as an irregular pleural line, subpleural consolidations, focal and lobar consolidation and signs of interstitial involvement can be used to distinguish between several pathologies. This work offers a comprehensive overview of pediatric LUS in cases of the most common pediatric RTIs including bacterial and viral pneumonia, bronchiolitis, and COVID-19.

Lung Ultrasound in Children with Respiratory Tract Infections: Viral, Bacterial or COVID-19? A Narrative Review

This evidence-based consensus aims to establish the role of point-of-care lung ultrasound in the management of pneumonia and bronchiolitis in paediatric patients. A panel of thirteen experts form five Polish tertiary pediatric centres was involved in the development of this document. The literature search was done in PubMed database. Statements were established based on a review of full-text articles published in English up to December 2019. The development of this consensus was conducted according to the GRADE (Grading of Recommendations, Assessment, Development and Evaluations)-adopted and Delphi method. Initially, 22 proposed statements were debated over 3 rounds of on-line discussion and anonymous voting sessions. A total of 17 statements were agreed upon, including four statements referring to general issues, nine referring to pneumonia and four to bronchiolitis. For five statements experts did not achieve an agreement. The evidence supporting each statement was evaluated to assess the strength of each statement. Overall, eight statements were rated strong, five statements moderate, and four statements weak. For each statement, experts provided their comments based on the literature review and their own experience. This consensus is the first to establish the role of lung ultrasound in the diagnosis and management of pneumonia and bronchiolitis in children as an evidence-based method of imaging.

Consensus on the Application of Lung Ultrasound in Pneumonia and Bronchiolitis in Children.

Introduction: Viral bronchiolitis is a common cause of lower respiratory tract infection in the first year of life, considered a health burden because of its morbidity and costs. Its diagnosis is based on history and physical examination and the role of radiographic examination is limited to atypical cases. Thus far, Lung Ultrasound (LUS) is not considered in the diagnostic algorithm for bronchiolitis. Methods: PubMed database was searched for trials reporting on lung ultrasound examination and involving infants with a diagnosis of bronchiolitis. Results: Eight studies were suitable. Conclusions: This review analyzed the current evidence about the potential usefulness of LUS in the clinical management of bronchiolitis. Literature supports a peculiar role of LUS in the evaluation of the affected children, considering it as a reliable imaging test that could benefit the clinical management of bronchiolitis.

Acute Bronchiolitis: Is There a Role for Lung Ultrasound?

Lung ultrasound has become increasingly used in both adult and pediatric populations, allowing the rapid evaluation of many lung and pleura diseases This popularity is due to several advantages of the method such as the low cost, rapidity, lack of ionizing radiation, availability of bedside and repeatability of the method These features are even more important after the outbreak of the SARS-CoV-2 pandemic, given the possibility of recognizing through ultrasound the signs of interstitial lung syndrome typical of pneumonia caused by the virus The purpose of this paper is to review the available evidence of lung ultrasound (LUS) in children and its main applications in pediatric diseases

Lung Ultrasound: Its Findings and New Applications in Neonatology and Pediatric Diseases

Respiratory syncytial virus is the main pathogen responsible for bronchiolitis. Usually, there is no indication to perform diagnostic imaging or run laboratory tests in patients with bronchiolitis since the diagnosis is based on the clinical presentation. Chest radiogram can be useful in severe cases. So far, lung ultrasound has not been considered as an alternative in guidelines for imaging diagnosis of bronchiolitis. The aim of the study was to compare lung ultrasound and chest X-ray findings in children with bronchiolitis. In our study we retrospectively compared diagnostic imaging findings in children with confirmed respiratory syncytial virus infection. The study included 23 children aged 2 weeks to 24 months and 3 children older than 24 months. Chest X-ray showed lesions in only 4 cases, whereas ultrasound abnormalities were found in 21 patients. Pathologies revealed by chest X-ray were the same for all 4 cases and consisted of an enlarged hilus and peribronchial cuffing. Sonographic lesions included inflammatory consolidations larger than 10 mm in 11 patients, small consolidations (<10 mm diameter) in 8 patients, interstitial syndromes in 6 patients, and alveolar-interstitial syndromes in 11 patients. A small amount of pleural effusion was detected in 3 patients. Considering safety, short time of examination, high sensitivity in finding pleural effusion, small consolidations and signs of interstitial infiltrations, transthoracic lung ultrasound may be useful in the diagnosis of bronchiolitis.

Comparison of lung ultrasound and chest X-ray findings in children with bronchiolitis.

The authors present a case of a 61-year-old female patient suffering from tracheobronchopathia osteochondroplastica (TBO). Etiology of this unit is uncertain. TBO is characterised by presence of multiple nodules of various size, situated in the submucosa of the trachea and major bronchi. The course is usually benign, until lesion obstructs the bronchial lumen. In the presented case, occluded middle lobe bronchi resulted in peripheral atelectasis of the lung.
