Specification and guideline for technical aspects and scanning parameter settings of neonatal lung ultrasound examination.

Lung ultrasound (LUS) is now widely used in the diagnosis and monitor of neonatal lung diseases. Nevertheless, in the published literatures, the LUS images may display a significant variation in technical execution, while scanning parameters may influence diagnostic accuracy. The inter- and intra-observer reliabilities of ultrasound exam have been extensively studied in general and in LUS.

Wet lung leading to RDS: the lung ultrasound findings and possible mechanisms - a pilot study from an animal mode.

Background: Clinically, the lung ultrasound (LUS) showed wet lung could cause respiratory distress syndrome (RDS) in newborns. This work aimed to investigate LUS changes over time and its potential mechanism as alveolar fluid increase in a rabbit model.

Methods: A total of 35 New Zealand Rabbits were randomly assigned to seven groups.

Lung ultrasound to quantitatively evaluate extravascular lung water content and its clinical significance.

Background: As we all know, pulmonary edema can be diagnosed by lung ultrasound (LUS), but how to accurately and quantitatively evaluate lung water content by ultrasound is a difficult problem that needs to be solved urgently. B-line assessment with LUS has recently been proposed as a reliable, noninvasive semiquantitative tool for evaluating extravascular lung water (EVLW). To date, however, there has been no easy quantitative method to evaluate EVLW by LUS.

Using lung ultrasound to quantitatively evaluate pulmonary water content.

Background: Increases in extravascular lung water (EVLW) can lead to respiratory failure. This study aimed to investigate whether the B-line score (BLS) was correlated with the EVLW content determined by the lung wet/dry ratio in a rabbit model.

Methods: A total of 45 New Zealand rabbits were randomly assigned to nine groups.
