Bedside pulmonary ultrasound has been established as an important tool for the evaluation of critically ill patients and has been proven to be helpful in the diagnosis of specific pathological features, such as interstitial oedema, consolidation and pleural effusion [Lung ultrasonographic examination allows for a rapid and reliable diagnosis of the lung water content and pulmonary ventilation status [The pathophysiological result of hydrostatic pulmonary oedema caused by VA-ECMO is increased left ventricular (LV) afterload due to reverse ECMO flow in the aorta [Because the PaOAn increased incidence of pulmonary oedema during VA-ECMO treatment is closely associated with mortality. Moreover, the LUS score was used to predict the prognosis of ARDS caused by COVID-19 and paediatric diseases, and indicated that the LUS score was associated with a higher risk of PICU mortality and longer PICU stay days after 72 h of VV-ECMO support [There are several limitations of our study. First, it is important to note the retrospective design and the single-centre setting as limitations and that the small sample size may have led to selection bias. For further research, the sample size should be expanded for a stratified analysis. Second, the evaluation of back partitioning requires the patient to be moved, which increases the difficulty of nursing and has the risk of catheter displacement, and multiple measurements are required to ensure the accuracy of the data.Third, left heart decompression procedures have been implemented by numerous medical centers to improve pulmonary edema and lung ultrasound scores. However, it should be noted that our study did not include patients undergoing left heart decompression, therefore, our findings cannot be generalized to this population.
