“…The air bronchogram can be either static, where it is fixed within the consolidation, or dynamic, where it moves during the respiratory cycle. Dynamic air bronchograms indicate that the airways supplying the target lung tissue are clear and unobstructed 2–4 …”

“…Available evidence indicates a clear superiority of lung US as a screening tool over chest X-ray in terms of identifying various pulmonary conditions. The main indication of POCUS is the detection of pneumonia by visualizing focal B-lines, lung consolidation or hepatization, dynamic air bronchograms, subpleural abnormalities and/or irregular and thickened pleura [ 28 , 29 , 30 ]. A meta-analysis of 10 studies demonstrated that POCUS had a sensitivity of 95% and a specificity of 93% in diagnosing pneumonia, compared to chest X-ray which had a sensitivity of 69% and a specificity of 77% [ 31 ].…”

Sepsis and septic shock are life-threatening emergencies associated with increased morbidity and mortality. Hence, early diagnosis and management of both conditions is of paramount importance. Point-of-care ultrasound (POCUS) is a cost-effective and safe imaging modality performed at the bedside, which has rapidly emerged as an excellent multimodal tool and has been gradually incorporated as an adjunct to physical examination in order to facilitate evaluation, diagnosis and management. In sepsis, POCUS can assist in the evaluation of undifferentiated sepsis, while, in cases of shock, it can contribute to the differential diagnosis of other types of shock, thus facilitating the decision-making process. Other potential benefits of POCUS include prompt identification and control of the source of infection, as well as close haemodynamic and treatment monitoring. The aim of this review is to determine and highlight the role of POCUS in the evaluation, diagnosis, treatment and monitoring of the septic patient. Future research should focus on developing and implementing a well-defined algorithmic approach for the POCUS-guided management of sepsis in the emergency department setting given its unequivocal utility as a multimodal tool for the overall evaluation and management of the septic patient.

Context: Neonatal lung ultrasound is emerging as a useful clinical tool for the assessment of lung anatomy and management of various lung pathologies. In this review, we summarize normal lung ultrasound (LUS) findings and specific features of various lung morbidities. Evidence acquisition: A comprehensive literature search was conducted across multiple sources with relevant keywords with an additional filter of the age-group between 0 and 28 days. Findings: Apart from the description of normal newborn lungs, clinical and radiological features of a variety of lung pathologies were evaluated and incorporated in the review. Bedside LUS has evolved to be an important point-of-care imaging modality that can help in day-to-day clinical decision-making. It can be used in differentiating respiratory distress syndrome from transient tachypnea on the newborns, in the detection of pneumothorax, and in diagnosing pneumonia, pulmonary hemorrhage, and pleural effusion. Evidence supports the use of LUS scores to decide on the need for early rescue surfactant therapy with high sensitivity and specificity. Lung ultrasound scores obtained during the first 2 weeks after birth can help predict the likelihood of chronic lung disease/bronchopulmonary dysplasia. Once validated, it could be valuable for guiding early intervention and evaluation of new treatments. Conclusion: Neonatal lung ultrasound is emerging as a vital monitoring tool in critically ill infants with lung disease. It will be valuable in the early diagnosis, management, and prognosis of these patients.
